Abstract

Magnetic circuits in rotation systems for generating electric and mechanical power such as machines in electric cars and ships. This rotation system is composed of three parts. One is a revolving field magnet (22) fixed at the axis (21). The second part is armatures with M type of magnetic circuits for generating the mechanical power. The third part is armatures with inverse Y type of eletromagnets for generating the electric power that generates the electromotive force by receiving the induced magnetic flux from the revolving field magnet (22) and the armatures for generating the mechanical power.

Description

TECHNICAL FIELD

This invention relates to a magnetic circuit in a rotation system.

More particularly, this invention relates to a magnetic circuit in the rotation system obtaining a mechanical rotation power by transforming the electric energy into magnetic energy, and at the same time necessary electric and mechanical energy by transforming the four magnetic flux summed in one magnetic circuit into electric energy and mechanical energy: the flux generated from an induction electromagnet for magnetic flux circulation in am armature for generating the mechanical power, the flux generated from an induction electromagnet for magnetic flux circulation in am armature for generating the mechanical power, and the flux generated from the field magnet.

BACKGROUND ART

The revolving devices that have been invented so far can be categorized into three types: motors that generate revolving force by using electrical energy, generators that generate electric power by using mechanical power, and dynamotor which are made by mechanically or electrically connecting generators and motors.

In the above-mentioned revolving devices most of the cases tried to simply change the device structure in order to maximize the efficiency of output power versus input power. This effort, however, has not provided many results besides the fact that it has only removed the ripple phenomenon.

As one can see, efforts to maximize efficiency have always been made. One of these is the patent (Korean patent No: 90-382. Title of the invention: magnetic circuit and magnetic induction method of rotator for generating mechanical and electric power, Issuing date: Jan., 12, 1995) issued to this inventor. As described in FIG. 1 , the invention is composed of revolving field magnet( 2 ) which rotates with the attractive and repulsive force of the magnetic field, the armatures for generating the mechanical power( 3 ) that are formed with the several coiled bolts which support rotation of the revolving field magnet( 2 ), the coiled armatures for generating the electric power( 4 ) which are made of conductors and are designed to receive the magnetic flux generated when the revolving field magnet( 2 ) rotates, the induction electromagnet for magnetic flux circulation( 5 ) which control the magnetic flux according to the rotational phase of the revolving field magnet( 2 ), and the induction means for magnetic flux circulation which include the circulation conductor(yoke)( 6 ) for circulating the magnetic flux induced on the induction electromagnet. Therefore, when the power source is connected to the input power lines (p 1 -p 18 ) in the armatures for generating the mechanical power( 3 ) and the induction electromagnet for magnetic flux circulation( 5 ), rotational force of the revolving field magnet( 2 ) is generated. At the same time, part of the flux induced at the induction electromagnet for magnetic flux circulation( 5 ) in the armatures for generating the electric power( 4 ) and the induction electromagnet for magnetic flux circulation( 5 ) in the armatures for generating the mechanical power is used to get the rotational force of the revolving field magnet( 2 ). Some of the remaining flux, the flux generated at the opposite side of the pole piece of the armatures for generating the mechanical power, first flows first through the induction electromagnet for magnetic flux circulation( 5 ) in armatures for generating the mechanical power and the circulation conductor(yoke)( 6 ), then flows through the induction electromagnet for magnetic flux circulation( 5 ) in armatures for generating the electric power, and finally summed with the flux from movement of the above mentioned revolving field magnet to generate the electromotive force. In the end, the amount of energy return is equal to the amount of energy that remains after the loss of energy experienced by the electromotive force. The reason why we call it “energy return” is because the remaining amount of energy in the electromotive force after the loss is applied to part of the power input.

The above-mentioned rotation system, however, generates too much heat the product due of intensive winding on the armatures for generating the electric power when the system is loaded, and is not able to fully utilize the magnetic flux from the cross area of the revolving field magnet. In addition, a partial concentration of magnetic force from the armatures for generating the mechanical power in this system prevents from obtaining a uniform torque. As the intensive wound areas of the armatures for generating the electric power and of the electromagnet for inducing magnetic flux circulation per same area increase vertically, the flux magnetic flux does not increase due to the small area of the field magnet as much as shrinked by them.

Also, in the motor, as the speed increases, the counter electromotive force becomes bigger and repulses the input power this lowers the current into the coil of the armatures for generating the mechanical power. Hence, the torque becomes small as the speed increases.

SUMMARY OF INVENTION

This invention is to solve the above problems and has four objectives. The first objective is to provide the magnetic circuit of the rotation system that provides high efficient electromotive force by constructing the system in such a way that the several armatures for generating the electric power correspond to the cross area of the revolving field magnet. Thus the system effectively induces the magnetic flux of the revolving field magnet on to the several armatures for generating the electric power.

The second objective of this invention is to provide a magnetic circuit for the rotation system that provides a uniform torque by splitting the single pole piece into several ones in the armatures for generating the mechanical power.

The third objective is to provide a magnetic circuit for the rotation system that provides a high degree of efficiency by maximizing the amount of the magnetic flux of the field magnet. This can be done by properly splitting, into highly balanced areas, the electromagnets for inducting magnetic flux circulation in the armatures for generating the electric power and in the armatures for generating the mechanical power, and at the same time by optimizing the coil wind-up area of the electromagnets.

By winding together and winding individually the electromagnets for inducting magnetic flux in armatures for generating the electric power and the electromagnets for inducting magnetic flux circulation in the armatures for generating the mechanical power with the two electromagnets separated by an air gap; and by applying power to the electromagnets for inducting magnetic flux circulation according to the rotational phase of the revolving field magnet, one of the magnetic fluxes generates the electromotive force and the rest magnetic fluxes provide the rotational force.

The fifth objective is to provide a magnetic circuit for the rotation system that maintains or increases the torque regardless of an increase in the counter electromotive force induced by increasing rotational speed. By the electric load produced in countering the electromotive force generated in armatures for generating the electric power, the polarity of the pole pieces in the armatures for generating the electric power changes to the same polarity as the pole pieces in the armatures for generating the mechanical power. This will increase the mechanical force regardless of an increase in the counter electromotive force that is induced by increasing rotational speed.

According to the present invention there are provided; a rotatory means which is fixed at an axis and rotates by the repulsive and attractive magnetic field forces; a means for generating mechanical power which is composed of several projecting parts or slots in a circular stator and generates the magnetic force to the revolving field magnet to increase revolving movement, when the input power is applied to;

Spaced with the air gap, with coil either in common or individually. Also, it provides a circulation conductor(yoke) for circulating the magnetic flux from the induction means for the magnetic flux circulation and from the means for generating electric power.

According to another aspect of the invention are provided; a rotatory means which is fixed at an axis and rotates by the repulsive and attractive forces of magnetic field; a means (armature) for generating the mechanical power that is composed of several projecting parts or slots in a circular stator and generates the magnetic force to the revolving field magnet to increase revolving movement, when the input power is applied to;

Also a transformative means is the means in which the electromotive force produced at the means armature for generating the electric power increases the torque of the mechanical power by changing the polarity of the pole piece in the armature for generating the electric power when the system is loaded.

Also, in order to control the magnetic flux according to the rotational phase of the revolving field magnet, a magnetic circuit in the rotation system for generating the electric power provides the induction means for magnetic flux circulation that part of the above-mentioned means for generation the mechanical power and part of the above-mentioned means for generating the electric power are wound, spaced with the air gap, with coil either in common or individually.

DETAILED DESCRIPTION

FIGS. 2A and 2B illustrate the magnetic circuits in the rotation system for generating the electric power and the mechanical power in the present invention.

As shown in FIG. 2A , a revolving field magnet ( 22 ) is rotatable around a fixed axis ( 21 ) and a circular stator ( 23 ) includes the electromagnets ( 27 ) for inducing magnetic flux circulation in a leg of an inverse type core. A circulation conductor (yoke) ( 26 ), of the circular stator forms a magnetic circuit. This magnetic circuit is composed of three parts. One is the inverse Y type magnetic circuit on which coils ( 20 ) are wound for inducing magnetic flux circulation in an armature ( 24 ) for generating the mechanical power. The second is the projecting part of an M type magnetic circuit that, is spaced with an air gap, ( 38 ) from yoke ( 26 ) and is next to the inverse Y core of the electromagnet ( 27 ) for inducing magnetic flux circulation. Coils are wound on the M type core for generating electromotive force by receiving the magnetic flux from the revolving field magnet ( 22 ) and from the electromagnet ( 27 ) for inducing magnetic flux circulation in the armature ( 25 ) for generating the electric power. This generates magnetic flux circulation in coils ( 29 ) wound together on the leg of the inverse Y core and induces the flow of the magnetic flux. In order to complete the magnetic circuit, the air gap ( 28 ) exists between the circulation conductor (yoke) ( 26 ) and electromagnet ( 27 ) for inducing magnetic flux circulation in the armature ( 28 ) for generating the electric power. Coils ( 29 ) in the slots of the armature ( 24 ) for generating the mechanical power are included in this circuit in order to acquire a higher torque.

FIG. 2B is different in that FIG. 2B has I type magnetic circuit ( 27 ′) rather than the inverse Y type described in FIG. 2 A. Because there is no difference except for the above-mentioned one, we skip the explanation.

With reference to FIGS. 3A and 3B , we will explain the magnetic polarity change of the magnetic circuit for the revolving movement of the revolving field magnet. For the explanation, we take. the double-pole single phase case.

As shown in FIG. 3A , when N pole and S pole of the revolving field magnet are at the vertical axis, switching power is applied as will be shown in FIG. 4A , according to the detected phase of the revolving field magnet by a sensor (not shown) for phase detection of the revolving field magnet fixed at the axis ( 21 ). This switching power causes the input line (pi) of the coil to induce N pole at the inverse Y type armature ( 24 B) for generating the mechanical power positioned at the front point of N pole of the revolving field magnet ( 22 ) when it rotates clock-wise; to induce S pole at the inverse Y type armature ( 24 A) for generating the mechanical power at the position of S pole of the revolving field magnet ( 22 ).

Also, the switching power induces N pole at the pole piece of the inverse Y type in the armature ( 24 C) for generating the mechanical power positioned at 15° under the 0° line and S pole at the pole piece of the inverse Y type in the armature ( 24 D) for generating the mechanical power positioned at 15° above the 180° line. In this way, we can get the initial rotational force.

As shown in FIG. 3B , the revolving field magnet( 22 ) which acquired the initial rotation force can get a constant rotational armature for generating power according to the detected phase by the phase detection sensor (not shown) at the axis. Since the same explanation can be applied to the I type projecting structure of the armature for generating the mechanical power in FIG. 2B , we skip the I type case.

The magnetic flux flow diagram FIGS. 4A and 4B of the magnetic circuit shows the magnetic flux produced from the armature for generating the mechanical power ( 24 E) when the power is applied to the armature. This magnetic flux follows the revolving field magnet ( 22 ) which travels past the armature for generating the mechanical power ( 24 F) (opposite site of 24 E), where power was transmitted from the switching circuit and forms a magnetic circuit along the path of circulation conductor (yoke) ( 26 ).

When power is applied to wound coils which are common to the leg ( 27 B) of the armature for generating the mechanical power ( 24 E) and the electromagnet ( 27 A) for inducing magnetic flux circulation in armature ( 25 ), electric power is produced.

On the other hand, magnetic flux is also formed in a rotation which produces the mechanical power. Air gap ( 28 ) forms a magnetic circuit between the electromagnet ( 27 ) for inducing magnetic flux circulation [( 27 )] and the circulation conductor (yoke) ( 26 ).

When power is applied to coils ( 29 ) wound in common on the leg ( 27 B) of the inverse Y type or I type armature for generating the mechanical power ( 24 E) and the electromagnet ( 27 A) for inducing magnetic flux circulation in the armature ( 25 ) for generating the electric power the intended magnetic flux is formed. Part of this magnetic flux is used to obtain the rotational force and the rest is used for generating the electric power. By cutting off the magnetic flux from the coils wound in the armature ( 25 ) for generating the electric power, the electromotive force is obtained. The magnetic flux from the revolving field magnet ( 22 ) also combines with the flux from the armature ( 25 ) for generating the electric power and the electromotive force increases.

FIG. 5 shows a diagram of an example of the switching power supply circuit which supplies the switching power to the rotator according the present invention.

As shown in FIG. 5 , the circuit changes the polarity for every phase of about 90 degrees of the revolving field magnet. For this switching, the revolving field magnet phase detector ( 50 ) for detecting the phase of the revolving field magnet is used. Although it can be realized in various ways such as with resolvers and encoders, in the present invention, the revolving field magnet phase detector comprises a photo-diode ( 51 ), a photo-transistor ( 52 ), and a phase-detecting plate ( 53 A, 53 B) which detects the rotated angle of the revolving field magnet ( 22 ) is located between the photo-diode ( 51 ) and the photo-transistor ( 52 ).

This revolving field magnet phase detector ( 50 ) is connected to the switching power supply circuit ( 60 ) through several NOT logic devices( 55 , 56 , 57 , 58 ). In this way, two different outputs from the switching power supply ( 60 ) can be applied to the motor.

The switching power supply circuit ( 60 ) comprises first, second, third and fourth switching parts ( 61 , 62 , 63 , 64 ) for providing the electric power to the rotation unit ( 80 ). Since each part ( 61 , 62 , 63 , 64 ) has the same configuration, we describe only the first switching part ( 61 ). The first switching part ( 61 ) comprises darlington transistors (Q 61 , Q 62 ), voltage-dividing resistors (R 61 , R 62 ), and diodes (D 61 , D 62 ) to prevent the switching voltage from reversing. And the transistors (Q 61 . Q 62 ) of the first switching part ( 61 ) and the transistors (Q 67 , Q 68 ) of the second switching part ( 62 ) are turned on at the same time. In the same way, the transistors (Q 63 and Q 64 ) in the third switching part ( 63 ) and the transistors (Q 65 , Q 66 ) in the fourth switching part ( 64 ) are also turned on at the same time so that the rotation unit ( 80 ) is supplied with a switching pulse voltage of which phase is 90 degrees. Thus, the switching power supply circuit ( 60 ) changes the direction of the current applied to the coil of the armature ( 24 ) for generating the mechanical power and the coil of the armature ( 25 ) for generating electric power whenever the phase of the revolving field magnet ( 22 ) changes by every 90 degrees. The comparator (CP) of the above-mentioned revolving field magnet phase detector ( 50 ) compares the reference voltage Vref . applied to an inverting input terminal (−) with an output voltage of the phototransistor ( 52 ) applied to a noninverting input terminal (+).

The output of the photo-transistor ( 52 ) is generated if the light of the photo-diode( 51 ) is transmitted caused by the phase angle detection from the phase-detecting plates ( 53 A, 53 B). In conclusion, the output of the above —mentioned switching power supply circuit, with alternatively changing its polarity, is supplied to the input line (pa′) of coils in the rotation unit ( 80 ).

FIGS. 6A and 6B are magnetic circuit diagrams of another embodiment of the rotation system for generating the electric and mechanical power in the present invention. As shown in FIG. 6A , the structural difference from the abovementioned embodiment is in the modification in the structure of the armature ( 74 A, 74 B) for generating the mechanical power. The modification includes the combination of 2 pairs or more of inverse Y type in order to induce the magnetic flux in the armature for generating the electric power and for the armature for generating the mechanical power when polarity change occurs, such as from S pole to N pole, from N pole to N pole, and from S pole to S pole and to smoothly rotate the revolving field magnet. Also, to increase the torque, a coil is wound at the neck of the armature ( 74 A, 74 B) for generating the mechanical power. If necessary, apparatuses on the armature may be added.

The difference in FIG. 6B from FIG. 6A is that the structure of the armature ( 75 A, 75 B) for generating the mechanical power is ‘H’ type. In these regards, ‘H’ type of the armature ( 75 A, 75 B) for generating the mechanical power may have an air gap vertically along the center so a different shape of armature i. e. a pair of symmetric ‘F’ type of armature can be formed and used for generating the mechanical power. With that one exception, the structure and the operation are the same. Also, the operation principle of FIG. 6A and 6B is the same as that of FIG. 3A and 3B . And, because the operation principles are almost the same and are self-evident to engineers in this field.

We skip the explanation of the operation.

FIG. 7A shows that when N pole is induced at the pole piece ( 75 ) of the armature ( 74 ) for generating the mechanical power by inducing N pole at the neck ( 71 ) of the armature ( 74 ) for generating the mechanical power and the leg( 72 ) of the electromagnet ( 72 ) for inducting magnetic flux circulation, a small S (Sa) pole is induced at the pole piece in the armature for generating the electric power which is not influenced by the mechanical rotational force.

FIG. 7B shows that in the present invention the electromotive force is generated when the induced magnetic flux from the electromagnets for inducting magnetic flux circulation and from the rotation of the revolving field magnet are interlinked to the coils wound at the armature for generating the electric power. When this electromotive force is connected to electric load, the polarity at the pole piece of the armature for generating the electric power changes from small S (Sa) pole to N (Nb) pole according to the amount of the electromotive force and load. This presents a phenomenon of maintaining or increasing the torque even when the revolving field magnet rotates at a high speed.

This phenomenon can be explained using the equation of the relationship between the relationship between the number of rotations and the torque of a motor, Eb=Ia·Ra+Ec, where Eb is input electric power, Ia input current, Ra coil resistance, and Ec counter electromotive force.

In previous technology, as the number of rotations is increased, the counter electromotive force (Ec) is increased but the input current (Ia) inversely reduced. As a result, the mechanical torque reduces. In the present invention, however, when the system is loaded, the polarity (Nb) change (see FIG. 7 ) at the pole piece of the armature for generating the electric power maintains and increases the torque even when the number of rotations of the revolving field magnet increases.

As explained, the magnetic circuit of the rotation system for generating the mechanical and electric power generates the magnetic flux at the armature for generating the mechanical power and the armature for generating the electric power with the switching power from a drive circuit. These fluxes increase the rotational force of the revolving field magnet. At the same time, the electromotive force is generated because the armature for generating the electric power cuts the flow of the magnetic flux as the magnetic flux from the electromagnet for inducting magnetic flux circulation and from the revolving field magnet flow through the armature for generating the electric power. Therefore, through this process, the electromotive force is re-used as a part of electric power consumption in the rotation system and the energy saving effect to reduce consumption of external electric power occurs.

The rotation system in the present invention is explained with the example of double pole and single-phase type but the same explanation can also be applied to double pole three phase or multi-pole multi-phase case.

We use the concept of the revolving field magnet and the stator armature but the same explanation can be applied to a system of revolving armatures and stationary field magnets.
