The present disclosure relates to a power generation apparatus using a permanent magnet.
In a driving source (i.e., a driving motor) of a conventional generator, driving capacity and a rotational speed are determined according to conditions of each manufacturer. Therefore, in order to generate a rated output of a generator, an output of a driving motor should be about three times an output of a motor generator. Therefore, the total efficiency of power generation is reduced and energy is severely wasted.
The present disclosure is directed to providing a power generation apparatus capable of achieving high energy efficiency.

First, referring to
The shaft 110 may be formed to pass through the first non-rotor 170, the second non-rotor 171, and the rotor 120. The rotor 120 is connected to the shaft 110 so that the rotor 120 may rotate along with the shaft 110 according to the rotation of the shaft 110. For example, the power supply 190 may supply power to the motor 192, and the rotor 120 may be rotated by the motor 192. The first non-rotor 170 and the second non-rotor 171 do not rotate regardless of the rotation of the shaft 110. Therefore, unlike in the drawings, the shaft 110 may pass through only the rotor 120, and may not pass through the first non-rotor 170 and the second non-rotor 171.
Further, the first non-rotor 170 and the second non-rotor 171 may be arranged at both sides of (i.e., above and below) the rotor 120. In

Meanwhile, a first dent portion 1120 may be formed in the second portion 122, and the second dent portion 1121 may be formed in the third portion 123. As shown in the drawing, the first dent portion 1120 may be formed on an entire surface of the second portion 122 or on a portion of the surface of the second portion 122. The second dent portion 1121 may be formed on the entire surface of the third portion 123 or on a portion of the surface of the third portion 123.
Further, the first dent portion 1120 may have a shape in which a depth thereof increases toward the shaft 110. The first dent portion 1120 may have an inclined shape. An angle formed by a surface S2 of the first dent portion 1120 and a virtual plane P2 of the second portion 122 may compose an acute angle 0. Here, the virtual plane P2 of the second portion 122 may be parallel to a central plane P1 of the rotor 120. In other words, the first dent portion 1120 may include a first region and a second region, wherein the first region may be closer to the shaft 110 than the second region and the depth of the first region may be greater than the depth of the second region.
The second dent portion 1121 may also have a shape in which the depth thereof increases toward the shaft 110. The second dent portion 1121 may have an inclined shape. Alternatively, the second dent portion 1121 may include a third region and a fourth region, wherein the third region may be closer to the shaft 110 than the fourth region and the depth of the third region may be greater than the depth of the fourth region.
Meanwhile, the first portion 121 may have a cylindrical shape as shown, or may have a polygonal prism shape unlike that shown.

The first protrusion 1170 may include a fifth region and a sixth region, wherein the fifth region may be closer to the shaft 110 than the sixth region and the height of the fifth region may be greater than the height of the sixth region.
The second non-rotor 171 is formed to face the third portion 123. The second non-rotor 171 may have a truncated conical shape. The second non-rotor 171 includes a second protrusion 1171 protruding toward the second dent portion 1121 (or the third portion 123). The second protrusion 1171 may be formed on the entire surface of the second non-rotor 171 or on a portion of the surface of the second non-rotor 171. The second protrusion 1171 may have a shape in which the height thereof increases toward the shaft 110. The second protrusion 1171 may include a seventh region and a eighth region, wherein the seventh region may be closer to the shaft 110 than the eighth region and the height of the seventh region may be greater than the height of the eighth region.
Alternatively, the first non-rotor 170 or the second non-rotor 171 may have a truncated polygonal pyramid shape unlike that shown.

The plurality of second magnet units 221, 222, and 225 are arranged on the rotor 120 (i.e., the second portion 122 or the first dent portion 1120). The plurality of second magnet units 221, 222, and 225 may form a plurality of columns (e.g., three columns) about the shaft 110. The second magnet units 221, 222, and 225 have the first polarity (e.g., the N pole).
The plurality of third magnet units 221a, 222a, and 225a are arranged on the rotor 120 (i.e., the third portion 123 or the second dent portion 1121). The plurality of third magnet units 221a, 222a, and 225a may form a plurality of columns (e.g., three columns) about the shaft 110. The third magnet units 221a, 222a, and 225a have a second polarity (e.g., an S pole).
The plurality of fourth magnet units 271a, 272a, and 275a are arranged on the second non-rotor 171 (i.e., the second protrusion 1171). The plurality of fourth magnet units 271a, 272a, and 275a may form a plurality of columns (e.g., three columns) about the shaft 110. The fourth magnet units 271a, 272a, and 275a have the second polarity (e.g., the S pole).
A repulsive force is generated between the plurality of first magnet units 271, 272, and 275 and the plurality of second magnet units 221, 222, and 225, and a repulsive force is generated between the plurality of third magnet units 221a, 222a, and 225a and the plurality of fourth magnet units 271a, 272a, and 275a.
An example of an arrangement of the plurality of first magnet units 271, 272, and 275 and the plurality of fourth magnet units 271a, 272a, and 275a will be described below with reference to
The plurality of fifth magnet units 321 are provided on the first portion 121. The fifth magnet units 321 may form one column or a plurality of columns. The fifth magnet units 321 may have the second polarity (e.g., the S pole). The plurality of fifth magnet units 321 may be provided on a surface of the first portion 121. Alternatively, a groove may be formed in the first portion 121 and the plurality of fifth magnet units 321 may be arranged in the groove.
The plurality of sixth magnet units 371 is provided on the supporter 370. The sixth magnet units 371 may form one column or a plurality of columns. The sixth magnet units 371 may have the first polarity (e.g., the N pole). A groove may be formed in the supporter 370 and the plurality of sixth magnet units 371 may be arranged in the groove. Alternatively, the plurality of sixth magnet units 371 may be arranged on a surface of the supporter 370.
At least some of the plurality of fifth magnet units 321 and at least some of the plurality of sixth magnet units 371 may face each other. An attractive force is generated between the plurality of fifth magnet units 321 and the plurality of sixth magnet units 371.
The plurality of conductor units 391 are arranged between the first portion 121 and the supporter 370. Particularly, the plurality of conductor units 391 may be arranged between the plurality of fifth magnet units 321 and the plurality of sixth magnet units 371. The conductor units 391 may include any material as long as it is a conductive material such as copper, aluminum, gold, silver, indium tin oxide (ITO), indium zinc oxide (IZO), or the like. Alternatively, the conductor units 391 may be, for example, in the form of a wire wound around a metal.
As the rotor 120 rotates, the plurality of fifth magnet units 321 also rotate, the plurality of conductor units 391 are arranged in the attractive force generated by the plurality of fifth magnet units 321 and the plurality of sixth magnet units 371, and thus an induced current may be generated in the plurality of conductor units 391. The plurality of conductor units 391 may be supported by or fixed to, for example, the supporter 370.
An example of an arrangement of the plurality of fifth magnet units 321, the plurality of sixth magnet units 371, and the plurality of conductor units 391 will be described below with reference to
Meanwhile, the first non-rotor 170 or the second non-rotor 171 is movable in an extending direction of the shaft 110 (see reference symbols D1 and D2). The first non-rotor 170 or the second non-rotor 171 may be moved using an actuator using, for example, electricity, hydraulic pressure, compressed air, or the like, or may be moved using a mechanical method using a gear or the like. The first non-rotor 170 or the second non-rotor 171 may be moved using any method as long as it may be moved using the method.
Particularly, a magnitude of the repulsive force generated between the plurality of first magnet units 271, 272, and 275 and the plurality of second magnet units 221, 222, and 225 may be adjusted by adjusting an interval between the first non-rotor 170 and the second portion 122. As mentioned above, the magnitude of the repulsive force generated between the plurality of third magnet units 221a, 222a, and 225a and the plurality of fourth magnet units 271a, 272a, and 275a may be adjusted by adjusting an interval between the second non-rotor 171 and the third portion 123.
The interval between the first non-rotor 170 and the second portion 122 and the interval between the second non-rotor 171 and the third portion 123 may be controlled to be the same or may be controlled to be different. A speed of the rotor 120 may be controlled to be set to a required value by a combination of the interval between the first non-rotor 170 and the second portion 122 and the interval between the second non-rotor 171 and the third portion 123.
Meanwhile, in the power generation apparatus according to some embodiments of the present disclosure, the first magnet units 271, 272, and 275, the second magnet units 221, 222, and 225, and the sixth magnet units 371 are described as having the first polarity (e.g., the N polarity), and the third magnet units 221a, 222a, and 225a, the fourth magnet units 271a, 272a, and 275a, and the fifth magnet units 321 are described as having the second polarity (e.g., the S polarity), but the present disclosure is not limited thereto. That is, the present disclosure is not limited to the polarity thereof as long as the repulsive force can be generated between the second portion 122 and the first non-rotor 170 (i.e., between the first magnet units 271, 272, and 275 and the second magnet units 221, 222, and 225) and a repulsive force can be generated between the third portion 123 and the second non-rotor 171 (i.e., between the third magnet units 221a, 222a, and 225a and the fourth magnet units 271a, 272a, and 275a). As mentioned above, the present disclosure is not limited to the polarity thereof as long as an attractive force can be generated between the fifth magnet units 321 and the sixth magnet units 371.
Although not shown separately, a magnetic shield is provided inside and/or outside the power generation apparatus and serves to shield a magnetic force generated inside the power generation apparatus from affecting the outside.
Meanwhile, the power supply 190 is electrically connected to the shaft 110. Further, the controller 199 for controlling the power supply 190 is connected to the shaft 110. For example, the power supply 190 supplies power to the motor 192, the shaft 110 rotates according to the rotation of the motor 192, and the rotor 120 rotates according to the rotation of the shaft 110. The power supply 190 may be a battery, but the present disclosure is not limited thereto. By using the battery, the power generation apparatus may be easily moved and provided and may be easily used at anyplace. Further, as will be described below, since the battery is not used much, it may be used for a long time even with a battery having small capacity.
Meanwhile, in the power generation apparatus according to some embodiments of the present disclosure, the power supply 190 supplies power to the motor 192, and the motor 192 supplies power to the rotor 120 while a period in which the rotor 120 rotates at a preset rotational speed, or for a preset time, for example, of 1,000 to 3,000 times. When the rotor 120 rotates at the preset rotational speed (after the rotor 120 rotates for the preset time), additional power may not be supplied to the rotor 120 for a predetermined time. A “preset interval” in which no power is supplied may be a fixed time, and may be a time varying according to the rotational speed of the rotor 120. During a period in which no additional power is supplied, the rotor 120 may continuously rotate using a magnetic field surfing operation. That is, the rotor 120 may rotate for a long time by magnetic field surfing (in comparison of the rotor which does not use magnetic field surfing). The period during which no power is supplied may be prolonged.
The magnetic field surfing is a concept similar to wind surfing using waves in the sea. When it is assumed that a magnetic force distribution wave of a magnet is regarded as a vector, the magnetic field surfing is to surf a stationary magnetic force vector wave with a rotating magnetic force vector wave. For example, the magnetic field surfing may be performed using a relative phase difference between a magnetic field generated between the plurality of first magnet units 271, 272, and 275 provided on the first non-rotor 170 and the magnetic field generated between the plurality of second magnet units 221, 222, and 225 provided on the rotor 120. As mentioned above, the magnetic field surfing may be performed using a relative phase difference between the magnetic field generated between the plurality of fourth magnet units 271a, 272a, and 275a provided on the second non-rotor 171 and the magnetic field generated between the plurality of third magnet units 221a, 222a, and 225a provided on the rotor 120.
Further, when the rotor 120 rotates slower than the preset speed or after the preset time has elapsed, the power supply 190 may supply power to the motor 192 again. Accordingly, the rotor 120 rotates at the preset speed again. As described above, while the rotor 120 rotates, the power supply 190 may repeat the supply and block of the power. For example, the supply and block of the power may be repeated at a specific period. Alternatively, the supply and block of the power may be aperiodically repeated on the basis of, for example, the speed of the rotor 120. For example, a degree of rotation of the rotor 120 may be checked using a speed sensor or the like, and the supply and block of the power may be repeated according to the checked result.
Meanwhile, when a surfing operation of the rotor 120 is not smoothly performed (or when a desired level of surfing is not achieved), the surfing operation may be reattempted by adjusting the intervals between the rotor 120 and the non-rotors 170 and 171. The intervals are important factors affecting the surfing operation of the rotor 120. As the intervals between the rotor 120 and the non-rotors 170 and 171 decrease, the repulsive force increases. When the intervals between the rotor 120 and the non-rotors 170 and 171 become specific values, a high speed may be achieved even with low power.
Meanwhile, an attractive force is generated between the plurality of fifth magnet units 321 and the plurality of sixth magnet units 371. However, as the rotor 120 rotates and the magnetic field surfing is performed, the plurality of conductor units 391 are arranged in the attractive force generated by the plurality of fifth magnet units 321 and the plurality of sixth magnet units 371, and thus an induced current may be generated in the plurality of conductor units 391. As a result, power may be generated. The generated power may be output to the outside. Alternatively, some of the generated power may be restored to the power supply 190.
Hereinafter, the magnetic field surfing operation will be described in more detail with reference to
First, the first non-rotor 170 will be described with reference to
First, referring to
The plurality of first magnet units 271, 272, and 275 spaced apart from each other are respectively arranged in the columns L1, L2, and L3. Particularly, the number of the plurality of first magnet units 271 arranged in the first column L1 and the number of the plurality of first magnet units 272 arranged in the second column L2 may be equal. For example, fourteen first magnet units 271, 272, and 275 may be respectively arranged in the columns L1, L2, and L3. The fourteen first magnet units 271, 272, and 275 are shown in the drawing, but the present disclosure is not limited thereto. For example, eleven to twenty-four first magnet units may be arranged.
Meanwhile, the same numbers of first magnet units 271, 272, and 275 are shown to be respectively arranged in the columns L1, L2, and L3, but the present disclosure is not limited thereto. According to the design, a different number of first magnet units 271, 272, and 275 may be arranged. For example, since the first column L1 is a column in direct contact with the shaft 110, the number of the first magnet units 271 may be smaller than that of each of the first magnet units 272 and 275 when there is a space limitation.
Further, as shown in
Further, a first distance P1 between the first column L1 and the second column L2 and a second distance P2 between the second column L2 and a third column L3 may be equal to each other, but the present disclosure is not limited thereto. According to the design, the first distance P1 and the second distance P2 may be different from each other.
Meanwhile, as shown in
Further, sizes of the first magnet units 271, 272, and 275 respectively arranged in the columns L1, L2, and L3 may be different from each other. The size of the first magnet unit 272 in the second column L2 may be greater than the size of the first magnet unit 271 in the first column L1. The size of the first magnet unit 275 in the third column L3 may be greater than the size of the first magnet unit 272 in the second column L2. Further, the sizes of the first magnet units 271 arranged in the respective columns (e.g., L1) may be equal to each other.
Further, when two straight lines a1 and a2 which point outward about the shaft 110 are drawn, the first magnet unit 271 in the first column L1, the second magnet unit 272 in the second column L2, and the first magnet unit 275 in the third column L3 may be in contact with both of the two straight lines a1 and a2. Here, the contact with the two straight lines a1 and a2 means that sidewalls of the first magnet units 271, 272 and 275 overlap the two straight lines a1 and a2. Meanwhile, according to the design, the straight lines a1 and a2 may not overlap entire sidewalls of the first magnet units 271, 272, and 275 (see
Meanwhile, the central axes CL of the first magnet units 271, 272, and 275 respectively arranged in the columns L1, L2, and L3 have a phase difference from magnetic field axes MC1, MC2, and MC5. As shown in the drawing, the central axes CL and the magnetic field axes MC1, MC2, and MC5 may not be parallel to each other.
For example, as shown in the drawing, there may be angular differences θ11, θ12, and θ13 between the corresponding central axes CL and magnetic field axes MC1, MC2, and MC5. The angular differences 011, 012, and 013 may compose acute angles in a first direction (e.g., counterclockwise) about the central axes CL. Meanwhile, the angular differences θ11, θ12, and θ13 between the corresponding central axes CL and magnetic field axes MC1, MC2, and MC5 may be completely equal to each other. Alternatively, the angular differences θ11, θ12, and θ13 may be different from each other. Alternatively, the angular differences θ11 and θ12 may be equal to each other, and the angular difference θ13 may be different from the angular differences θ11 and θ12. The angular differences may be changed according to the design.

As shown in
Next, the rotor 120 will be described with reference to
Referring to
The fourth column L4 of the rotor 120 rotates while facing the first column L1 of the first non-rotor 170, and the fifth column L5 of the rotor 120 rotates while facing the second column L2 of the first non-rotor 170. A sixth column L6 of the rotor 120 rotates while facing the third column L3 of the first non-rotor 170.
The plurality of second magnet units 221, 222, and 225 spaced apart from each other are respectively arranged in the columns L4, L5, and L6. Particularly, the number of the plurality of second magnet units 221 arranged in the fourth column L4 and the number of the plurality of second magnet units 222 arranged in the fifth column L5 may be equal. Thirteen second magnet units 221 are arranged in the fourth column L4, and thirteen second magnet units 222 are arranged in the fifth column L5. For example, eleven to twenty-four second magnet units 221, 222, and 225 may be respectively arranged in the fourth column L4 and the fifth column L5.
Meanwhile, the same numbers of second magnet units 221, 222, and 225 are shown to be respectively arranged in the columns L4, L5, and L6, but the present disclosure is not limited thereto. According to the design, different numbers of second magnet units 221, 222, and 225 may be arranged. For example, since the fourth column L4 is a column in direct contact with the shaft 110, the number of the second magnet units 221 may be smaller than that of each of the second magnet units 222 and 225 when there is a space limitation.
As described above, the fourth column L4, the fifth column L5, and the sixth column L6 rotate while facing the first column L1, the second column L2, and the third column L3, respectively. However, the number of the plurality of first magnet units 271 arranged in the first column L1 and the number of the plurality of second magnet units 221 arranged in the fourth column L4 are different from each other. As mentioned above, the number of the plurality of first magnet units 272 arranged in the second column L2 and the number of the plurality of second magnet units 222 arranged in the fifth column L5 may be different from each other.
Further, an interval W4 between the plurality of second magnet units 221 arranged in the fourth column L4 is smaller than an interval W5 between the plurality of second magnet units 222 arranged in the fifth column L5. As mentioned above, the interval W5 between the plurality of second magnet units 222 arranged in the fifth column L5 is smaller than an interval W6 between the plurality of second magnet units 225 arranged in the sixth column L6.
Further, a third distance P3 between the fourth column L4 and the fifth column L5 and a fourth distance P4 between the fifth column L5 and the sixth column L6 may be equal to each other, but the present disclosure is not limited thereto. According to the design, the third distance P3 and the fourth distance P4 may be different from each other.
A size of the second magnet unit 222 in the fifth column L5 may be greater than a size of the second magnet unit 221 in the fourth column L4. A size of the second magnet unit 225 in the sixth column L6 may be greater than a size of the second magnet unit 222 in the fifth column L5.
As shown in
The central axes CL3, CL4, and CL6 of the second magnet units 221, 222, and 225 respectively arranged in the columns L4, L5, and L6 are not parallel to corresponding magnetic field axes MC3, MC4, and MC6 (i.e., have a phase difference). For example, there may be angular differences θ21, θ22, and θ23 between the corresponding central axes CL3, CL4, and CL6 and magnetic field axes MC3, MC4, and MC6. The angular differences θ21, θ22, and θ23 may compose acute angles in a second direction (e.g., clockwise) about the central axes CL3, CL4, and CL6. Meanwhile, the angular differences θ21, θ22, and θ23 between the corresponding central axes CL3, CL4, and CL6 and magnetic field axes MC3, MC4, and MC6 may be completely equal to each other. Alternatively, the angular differences θ21, θ22, and θ23 may be different from each other. Alternatively, the angular differences θ21 and θ22 may be equal to each other, and the angular difference θ23 may be different from the angular differences θ21 and θ22. The angular differences may be changed according to the design.
The shapes of the unbalanced magnetic field vector waves are not limited to those in
Meanwhile, the third portion 123 of the rotor 120 (the magnet arrangement) is substantially the same as the second portion 122 of the rotor 120 (the magnet arrangement). The second non-rotor 171 (the magnet arrangement) is substantially the same as the first non-rotor 170 (the magnet arrangement). An arrangement relationship between the third portion 123 of the rotor 120 and the second non-rotor 171 is also substantially the same as an arrangement relationship between the second portion 122 of the rotor 120 and the first non-rotor 170.
In summary, the second non-rotor 171 and the third portion 123 of the rotor 120 are arranged to face each other. The plurality of fourth magnet units 271a, 272a, and 275a may be arranged on the second non-rotor 171 to form a plurality of columns (e.g., three columns). The plurality of third magnet units 221a, 222a, and 225a may be arranged on the third portion 123 of the rotor 120 in a plurality of columns (e.g., three columns).
Further, the third magnet units 221a, 222a, and 225a and the fourth magnet units 271a, 272a, and 275a may have unbalanced magnetic force vector waves. Central axes and magnetic field axes of the third magnet units 221a, 222a, and 225a are not parallel to each other (have a phase difference), and central axes and the magnetic field axes of the fourth magnet units 271a, 272a, and 275a are also not parallel to each other (have a phase difference).
Meanwhile, according to the design, the arrangement of the magnetic units 221, 222, 225, 221a, 222a, and 225a on the rotor 120 may be opposite of the arrangement of the magnetic units 271, 272, 275, 271a, 272a, and 275a on the non-rotors 170 and 171. That is, the magnetic units 221, 222, 225, 221a, 222a, and 225a on the rotor 120 may be arranged without a phase difference (e.g., similar to that in
Meanwhile, according to the design, the angular differences θ21, θ22, and θ23 of the magnetic units 221, 222, and 225 arranged on one surface of the rotor 120 may be different from angular differences of the magnetic units 221a, 222a, and 225a arranged on the other surface of the rotor 120. For example, in the magnetic unit 221, the angular difference θ21 between the central axis and the magnetic field axis may be 30°, and in the other magnetic unit 221a, the angular difference between the central axis and the magnetic field axis may be 40°.
Further, according to the design, an arrangement method of the magnetic units 221, 222, and 225 arranged on one surface of the rotor 120 and an arrangement method of the magnetic units 221a, 222a, and 225a arranged on the other surface may be different from each other. For example, as shown in
A relationship between the fifth magnet units 321, the sixth magnet units 371, and the conductor units 391 will be described with reference to
First, referring to
The plurality of sixth magnet units 371 are provided on the supporter 370. The sixth magnet units 371 may form one column or a plurality of columns. The sixth magnet units 371 may have a first polarity (e.g., an N pole). A groove 3701 may be formed in the supporter 370 and the plurality of sixth magnet units 371 may be arranged in the groove 3701.
A plurality of conductor units 3911 and 3912 are arranged between the first portion 121 and the supporter 370. The plurality of conductor units 3911 and 3912 may be arranged between the plurality of fifth magnet units 321 and the plurality of sixth magnet units 371. As shown in the drawings, the plurality of conductor units 3911 and 3912 may be fixedly provided on the supporter 370.
Meanwhile, the number of the plurality of fifth magnet units 321 and the number of the plurality of sixth magnet units 371 may be different from each other. The number of the plurality of fifth magnet units 321 and the number of the plurality of sixth magnet units 371 may be changed according to sizes of the rotor 120 and the supporter 370 and sizes of the fifth magnet units 321 and the sixth magnet units 371, respectively. For example, twenty-four fifth magnet units 321 may be provided on the first portion 121, and thirty sixth magnet units 371 may be provided on the supporter 370.
Further, the number of the plurality of conductor units 3911 and 3912 may also be different from the number of the plurality of fifth magnet units 321 and the number of the plurality of sixth magnet units 371. For example, since the plurality of conductor units 3911 and 3912 are fixed to the supporter 370, the number of the plurality of conductor units 3911 and 3912 may be related to the number of the plurality of sixth magnet units 371. For example, the number of the plurality of conductor units 3911 and 3912: the number of the plurality of sixth magnet units 371 may be n:1 (here, n is a natural number of 1 or more). For example, when thirty sixth magnet units 371 are provided, sixty conductor units 3911 and 3912 may be provided.
Here, referring to
For example, as shown in
As shown in
The sizes of the fifth magnet units 321 and the sixth magnet units 371 may vary according to a target production amount of power, sizes of the conductor units 3911 and 3912, and the like.
The shapes of the fifth magnet units 321 and the sixth magnet units 371 may be different from those shown in
According to the design, in the case in which the fifth magnet units 321 are parallelogramical and the sixth magnet units 371 are rectangular, power generation efficiency may be further improved in comparison to the case in which any of the fifth magnet units 321 and the sixth magnet units 371 may be parallelogramical or rectangular.
Further, referring to
Further, as shown in
Alternatively, as shown in
Similar to the fifth magnet unit 321, the seventh magnet unit 3321 may also have a trapezoidal shape.
As shown in
Next, referring to
As mentioned above, a distance from the shaft 110 to the second column L2 and a distance from the shaft 110 to the fifth column L5 may be different from each other. A distance from the shaft 110 to the third column L3 and a distance from the shaft 110 to the sixth column L6 may be different from each other.
Particularly, when the first magnet unit 271 and the second magnet unit 221 have S poles, the distance P12 may be shorter than the distance P11.
Similarly, a distance P11a from the shaft 110 to the fourth magnet units 271a and a distance P12a from the shaft 110 to the third magnet unit 221a may be different from each other. Further, a distance from the shaft 110 to the fourth magnet unit 272a and a distance from the shaft 110 to the third magnet unit 222a may be different from each other. A distance from the shaft 110 to the fourth magnet unit 275 a and a distance from the shaft 110 to the third magnet unit 225a may be different from each other.
Here, when the fourth magnet unit 271a and the third magnet unit 221a have N poles, the distance P11a from the shaft 110 to the fourth magnet unit 271a may be longer than the distance P12a from the shaft 110 to the third magnet units 221a.
Referring to
Due to the biased arrangement of the plurality of fourth magnet units 271a, 272a, and 275a and the plurality of third magnet units 221a, 222a, and 225a (i.e., some of the fourth magnet units 271a, 272a, and 275a face some of the third magnet units 221a, 222a, and 225a), a flow of the magnetic field is concentrated while rotating from the outside toward the central portion (see a reference symbol M2, and this is referred to herein as a magnetic field tornado).
Further, due to the biased arrangement of the plurality of first magnet units 271, 272, and 275 and the plurality of second magnet units 221, 222, and 225 (i.e., some of the first magnet units 271, 272, and 275 face some of the second magnet units 221, 222, and 225), a flow of the magnetic field is diffused to the outer side (outer peripheral portion) while rotating at the central portion (see a reference symbol Ml, and this is referred to herein as a magnetic field cyclone).
That is, due to the arrangement of the magnetic units in the rotor 120, the first non-rotor 170 and the second non-rotor 171, a rotation cycle is formed (induced) in a direction from the outside (outer circumference) to a center of rotation, a rising center, and the outside (outer peripheral portion) (by rotational diffusion). This is a Möbius cyclone phenomenon, resulting in a magnetic field induction.
A large magnetic field flow such as the magnetic field tornado or the magnetic field cyclone assists the stable rotation of the rotor 120. A continuous magnetic field Möbius rotation routine is formed and thus a rotation effect occurs.
Here, when the rotor 120 includes the first dent portion 1120 and the second dent portion 1121, the second magnet units 221, 222, and 225 are arranged in the first dent portion 1120, and the third magnet units 221a, 222a, and 225a are arranged in the second dent portion 1121, the magnetic field tornado and the magnetic field cyclone may be larger. The aforementioned results are because an interval A between the first dent portion 1120 and the second dent portion 1121 is reduced because there are the first dent portion 1120 and the second dent portion 1121. Therefore, this is because a process of changing from the magnetic field tornado to the magnetic field cyclone may be performed with minimizing the leakage of the magnetic field.
Further, the rotor 120 includes the first dent portion 1120 and the second dent portion 1121, and the first non-rotor 170 and the second non-rotor 171 include the first protrusion 1170 and the second protrusion 1171, respectively. Accordingly, intervals between the plurality of first magnet units 271, 272, and 275 and the plurality of second magnet units 221, 222, and 225 and intervals between the plurality of third magnet units 221a, 222a, and 225a and the plurality of fourth magnet units 271a, 272a, and 275a may be stably adjusted, and the repulsive force between the plurality of first magnet units 271, 272, and 275 and the plurality of second magnet units 221, 222, and 225 and the repulsive force between the plurality of third magnet units 221a, 222a, and 225a and the plurality of fourth magnet units 271a, 272a, and 275a may be maximized. Further, since the first dent portion 1120 faces the first protrusion 1170 and the second dent portion 1121 faces the second protrusion 1171, the rotor 120, the first non-rotor 170, and the second non-rotor 171 may be implemented in a minimized space.
Here, a method of driving the power generation apparatus according to some embodiments of the present disclosure will be described with reference to
First, the power supply 190 supplies power for a first period. The first period may be determined by the sizes of the rotor 120, the first non-rotor 170, and the second non-rotor 171, the sizes and the magnetic force of the first magnet units 271, 272, and 275, the sizes and the magnetic force of the second magnet units 221, 222, and 225, the sizes and the magnetic force of the third magnet units 221a, 222a, and 225a, the sizes and the magnetic force of the fourth magnet units 271a, 272a, and 275a, the sizes and the magnetic force of the fifth magnet units 321, the sizes and the magnetic force of the sixth magnet units 371, and the like.
The first period may be, for example, a period during which the rotor 120 may sufficiently rotate so that the rotor 120 may have inertia. For example, the power supply 190 may supply power only for a period during which the rotor 120 rotates 1,000 to 3,000 times.
Next, the power supply 190 does not supply the power for a second period after the first period. Even when the power supply 190 does not supply the power, the rotor 120 may continuously rotate using the magnetic field surfing operation.
After the second period, the power supply 190 may supply the power again. In this manner, the power supply 190 may periodically repeat operations of supplying and blocking of the power.
Meanwhile, when a surfing operation of the rotor 120 is not smoothly performed (or when a desired level of surfing is not achieved), the surfing operation may be retried by adjusting the interval between the first non-rotor 170 and the rotor 120 and the interval between the second non-rotor 171 and the rotor 120.
While the rotor 120 rotates in this way, a current may be induced in the plurality of conductor units 391, and as a result, power may be generated. The generated power may be output to the outside. Alternatively, some of the generated power may be restored to the power supply 190.
Meanwhile, to describe the magnetic field surfing operation in more detail with reference to
Since the first repulsive force RP1 increases as a crossing area (an overlapped area) of the first magnet unit 271 and the second magnet unit 221 increases, the first repulsive force RP1 increases while the rotor 120 rotates.
At a time t2, a second repulsive force RP2 begins to be generated while the first magnet unit 272 in the second column L2 and the second magnet unit 222 in the fifth column L5 cross each other (or overlap each other). This is because the second magnet unit 222 in the fifth column L5 is arranged behind the second magnet unit 221 in the fourth column L4 with a phase difference therebetween.
A total repulsive force RPt may be gradually increased over the time t1 and the time t2. That is, the rotor 120 may rotate more strongly after the time t1 and the time t2 have elapsed.
At a time t3, a third repulsive force RP3 begins to be generated while the first magnet unit 275 in the third column L3 and the second magnet unit 225 in the sixth column L6 cross each other (or overlap each other).
In summary, a time at which the second magnet unit 221 in the fourth column L4 begins to overlap the first magnet unit 271 in the first column L1 and a time at which the second magnet unit 222 in the fifth column L5 begins to overlap the first magnet unit 272 in the second column L2 are different from each other. Therefore, as described above, stationary magnetic force vector waves of the first non-rotor 170 and the second non-rotor 171 are surfed with the rotating magnetic force vector wave of the rotor 120. Further, the angular differences θ11, θ12, and θ13 may compose acute angles counterclockwise about the central axes CL, and the angular differences θ21, θ22, and θ23 may compose acute angles clockwise about the central axes CL3, CL4, and CL6. With this configuration, when the rotor 120 rotates, the rotating magnetic force vector wave of the rotor 120 and the stationary magnetic force vector waves of the first non-rotor 170 and the second non-rotor 171 are connected to each other by continuous rotation.
As described above, the rotor 120 may stably rotate between the first non-rotor 170 and the second non-rotor 171 on the basis of the low power of the power supply 190.
In the power generation apparatus according to some embodiments of the present disclosure, the conductor unit 391 capable of generating power is arranged on the supporter 370, and thus the size of the power generation apparatus may be significantly reduced. That is, the power generation apparatus does not include a rotary device and a separate device for generating power by receiving a rotational force from the rotary device, and is merged into a single device. That is, the power generation apparatus may be embedded in one device. Therefore, the size of the power generation apparatus may be significantly reduced.
Further, in
Referring to
Particularly, the first dent portion 1120 and the second dent portion 1121 may have a stepped shape rising from the shaft 110 toward the outside. The first protrusion 1170 and the second protrusion 1171 may have a stepped shape that is complementary to the first dent portion 1120 and the second dent portion 1121 and descending from the shaft 110 toward the outside.
Further, a groove may be formed in a first portion 121, and the plurality of fifth magnet units 321 may be arranged in the groove.
First, referring to
Referring to
As described above, at least a portion of the first column L1 and at least a portion of the fourth column L4 may face each other, at least a portion of the second column L2 and at least a portion of the fifth column L5 may face each other, and at least a portion of the third column L3 and at least a portion of the sixth column L6 may face each other.
In this case, the number of the second magnet units 221 arranged in any one column (e.g., L4) among the plurality of columns L4, L5, and L6 of the rotor 120 may be equal to the number of the first magnet units 271 arranged in the column (e.g., L1) facing the column.
Further, the numbers of the second magnet units 222 and 225 arranged in the remaining columns (e.g., L5 and L6) among the plurality of columns L4, L5, and L6 of the rotor 120 may be different from the numbers of the first magnet units 272 and 275 arranged in the columns (e.g., L2 and L3) facing the columns. Particularly, the number of the second magnet units 222 arranged in any one column (e.g., L5) among the remaining columns (e.g., L5 and L6) may be smaller than the number of the first magnet units 272 arranged in the column (e.g., L2) facing the column. On the other hand, the number of the second magnet units 225 arranged in any one column (e.g., L6) among the remaining columns (e.g., L5 and L6) may be greater than the number of the first magnet units 275 arranged in the column (e.g., L3) facing the column.
For example, eighteen first magnet units 271, 272, and 275 are respectively arranged in the columns L1, L2, and L3 of the first non-rotor 170. The number of the second magnet units 221 arranged in the fourth column L4 of the rotor 120 may be eighteen, the number of the second magnet units 222 arranged in the fifth column L5 may be sixteen, and the number of the second magnet units 225 arranged in the sixth column L6 may be twenty. Here, the specific numbers are only exemplary.
Meanwhile, in
For example, sizes (or widths) of the second magnet units 221 arranged in the fourth column L4 and an interval W4 between adjacent second magnet units 221 are constant. Sizes (or widths) of the second magnet units 222 arranged in the fifth column L5 and an interval W5 between adjacent second magnet units 222 are constant. Sizes (or widths) of the second magnet units 225 arranged in the sixth column L6 and an interval W6 between adjacent second magnet units 225 are constant. The numbers of the second magnet units 221, 222, and 225 respectively arranged in the columns are different from each other. When the above conditions are satisfied, the points PB1 and PB2 may vary according to a greatest common divisor of the numbers of the second magnet units 221, 222, and 225 respectively arranged in the columns L4, L5, and L6 of the rotor 120. Particularly, the numbers of the second magnet units 221, 222, and 225 respectively arranged in the columns L4, L5, and L6 may not be equal to each other, and may have a greatest common divisor of 2 or higher.

The guide shafts 2307 are arranged between the lower support 2310 and the upper support 2320. The guide shafts 2307 are arranged to separate the lower support 2310 from the upper support 2320. For example, four guide shafts 2307 may be provided, and may be arranged at corners of the lower support 2310 and corners of the upper support 2320. The leveling feet 2610 may adjust a height of the lower support 2310.
The clutch 2510 and the motor 2001 may be arranged on the upper support 2320. The motor 2001 may rotate or may not rotate by an on/off operation of the clutch 2510. A battery may be included inside the motor 2001, or may be arranged outside the motor 2001. Further, the motor 2001 may be a direct current (DC) motor, but the present disclosure is not limited thereto.
Components such as the first non-rotor 2170, the second non-rotor 2171, the rotor 2120, the shaft 2110, and the like may be arranged in a space between the lower support 2310 and the upper support 2320. The shaft 110 is connected to the motor 2001, and may rotate according to an operation of the motor 2001. As described with reference to
A position of the first non-rotor 2170 (i.e., an interval between the first non-rotor 2170 and the rotor 2120) may be adjusted by rotating the first handle 2410. As mentioned above, a position of the second non-rotor 2171 (i.e., an interval between the second non-rotor 2171 and the rotor 2120) may be adjusted by rotating the second handle 2420.
For example, when the second handle 2420 is rotated, the bevel shaft 2224 is rotated and the bevel gear 2226 is rotated. The bevel shaft 2228 is also rotated through the bevel gear 2226. The ball screws 2413 and 2414 change a rotational motion of the bevel shaft 2228 to a linear motion (up and down motion) of the second non-rotor 2171.
For convenience of description, in
The plurality of first magnet units 271, 272, and 275 may be arranged on the first non-rotor 170 to form a plurality of columns, as shown in
The plurality of second magnet units 221, 222, and 225 may be arranged on a second portion 122 (e.g., an upper surface) of the rotor 2120, as shown in
The plurality of fifth magnet units 321 may be arranged on a first portion 121 (e.g., a side surface) of the rotor 2120, as shown in
Meanwhile, it is possible to implement a rotating device excluding the fifth magnetic units 321, the sixth magnet units 371, and the conductor unit 391. When the fifth magnetic units 321, the sixth magnet units 371, and the conductor unit 391 are excluded, the rotating device cannot generate electricity. Therefore, the rotating device is connected to a separate generator so that the generator may generate power using the rotation of the rotating device. For example, the rotating device and the generator may be mechanically connected. For example, the rotating device and the generator may be connected by a belt or may be directly connected by a metal structure. For example, as a shaft 110 of the rotating device rotates, a pulley of the generator is rotated along therewith, and thus the generator may produce electricity. A commercialized product may be used as the generator. An example of the rotating device may be implemented to have a shape similar to the shape shown in

For example, the magnetic unit may have four different heights El, E11, E12, and E13. As shown in the drawing, E11<E13<E12<E1.
Alternatively, the magnetic unit may have three different heights among the heights E1, E11, E12, and E13. For example, E11=E13<E12<E1, E11<E13=E12<E1, and E11<E13<E12=E1.
Alternatively, the magnetic unit may have two different heights among the heights E1, E11, E12, and E13. For example, E11=E13<E12=E1, and E11<E13=E12<E1.
When the heights E1, E11, E12, and E13 of the magnetic unit are not constant, a direction of an upper surface of the magnetic unit having a hexahedral shape may be adjusted. Accordingly, a direction of a magnetic force emitted from the magnetic unit may be adjusted.
Further, a rotational direction F is shown to be a clockwise direction, but the present disclosure is not limited thereto.
