Hence, the rotor A (3), the rotor B (8), the rotor C1 (12-1) and the rotor C2 (12-2) can be connected with each other. Thus, when the rotating shaft (10) is rotating, all of the rotors will be rotated together along the same orientation through the first connection device (101) and the second connection device (102). In addition, in an embodiment of the present invention, metal material can be selected as material of the first connection device (101) and the second connection device (102) such as aluminum alloy, especially a kind of heat-treated aluminum alloy.

Likewise, the through hole (151) is corresponded to center opening region of one end (1011) of the first connection device (101) and the through hole (161) is corresponded to center opening region of the other end (1022) of the second connection device (102), so the rotating shaft (10) can be passed through the through hole (151) of the bearing (150) and the through hole (160) of the bearing (16). Thus, when the through hole (151) and/or the through hole (151) collided with or made friction to the rotating shaft (10) during the energy-saving brushless motor-kinetic generator working rapidly, the bearing (1510 and/or bearing (160) will be rotated by the rotating shaft (10), so to decrease problems such as energy loss or heat generating.

Therein, a fastening member can be used as the connecting method described above, such as a kind of screw. Thus, after the rotating shaft (10) is passed through center region of the third connection device (103) and connected to the third connection device (103), when the primary stator ferrite core A (2) is connected to an input power source, the rotor A (3) and the rotor B (8) are driven to rotate by the primary stator ferrite core A (2), so the rotor C1 (12-1), the rotor C2 (12-2) and the third connection device (103) will be rotated along the same orientation.
It is clear that the primary stator ferrite core (2), the first electric generator set (110) and the second electric generator set (130) can be combined by only one third connection device (103) as the energy-saving brushless motor-kinetic generator of the present invention. In addition, volume of the energy-saving brushless motor-kinetic generator of the present invention can be minimized and higher output power can be obtained in the embodiment. For example, distances between the rotor C1 (12-1), the rotor A (6) and the stator ferrite core C (11) of the first end (1031) of the third connection device (103) at left side in
Finally, a whole structure of the primary stator ferrite core (2), the first electric generator set (110) and the second electric generator set (130) is disposed inside the housing (1), and when the first side cover (15) and the second side cover (16) are connected to two sides of the rectangular housing (1), the energy-saving brushless motor-kinetic generator of the present invention can be obtained, such as shown in

According to the above description, in a preferred embodiment of the present invention, 18 is selected as the first turn number of the high counter-electromotive force A (4) disposed on the primary stator ferrite core A (4), which is used as a driving device of input end. On the other hand, 24 is selected as the second turn number of the high counter-electromotive force B (7) and the turn number of the high counter-electromotive force C (14), which are selected as output devices. It is clear that with respect to the stator ferrite cores, the turn number of the stator ferrite core of output end is larger than the turn number of the stator ferrite core of input end.
Furthermore, with respect to pole numbers of permanent magnets of the rotors, in a preferred embodiment of the present invention, the rotor of the left side first electric generator set (110) is symmetric to the rotor of the right side second electric generator set (130), and pole number of the rotors of the first electric generator set (110) is also the same as pole number of the rotors of the second electric generator set (130) at the same time. In a preferred embodiment of the present invention, pole number of the permanent magnets (5-2) of the rotor A (3) near one side of the primary stator ferrite core A (2) of the first electric generator set (110) is 12, and pole number of the permanent magnets (5-1) of the rotor A (3) near one side of the stator ferrite core C (11) is 16, in which configuration of the pole number (i.e., 16) of the permanent magnets (5-1) of the rotor A (3) is the same as pole number of the permanent magnets (13-1) of the rotor C1 (12-1) near left side of the rotor A (3), such that the pole number of the first permanent magnet (13-1) of the rotor C1 (12-1) is selected as 16. Similarly, pole number of the permanent magnet B (9-1) of the rotor B (8) near one side of the primary stator ferrite core A (2) in the second electric generator set (130) is 12, and pole number of the permanent magnet B (9-2) of the rotor B (8) near one side of the ferrite core B (6) is 16, in which configuration of the pole number (i.e., 16) of the permanent magnet B (9-2) at this side is the same as pole number (i.e., 16) of the permanent magnet C2 (13-2) of the rotor C2 (12-2) near right side of the rotor B (8). Apparently, total pole numbers of the permanent magnet (5-1) and the permanent magnet (5-2) of the rotor A (3) of the first electric generator (110) are the same as total pole numbers of the permanent magnet (9-1) and the permanent magnet (9-2) of the rotor B (8) of the second electric generator (130).

Thus, when the energy-saving brushless motor-kinetic generator of the present invention is working, the plurality of turn numbers of the winding sets (215) formed by the high counter-electromotive force winding set of the primary stator ferrite core A (2) is connected to the driving power supply. For example, the power supply can provide an input driving voltage ranged in 36 to 72 Volts (corresponded in 3 to 20 Amps). Each of winding sheaths of the winding sets (215) produces variation of counter-electromotive force by the input driving voltage, so the rotor A (3) and the rotor B (8) can rotate by the permanent magnets on the adjacent rotor A (3) and the rotor B (8) induced by magnetic field of counter-electromotive force of the winding sheaths. According to rotating of the rotor A (2) and the rotor B (8), the rotor C1 (12-1) and the rotor C2 (12-2) can be also rotated along the same orientation by the connection structure of the first connection device (101), the second connection device (102) and the rotating shaft (10).

In addition, the housing (1) of the energy-saving brushless motor-kinetic generator (100) of the present invention is formed by heatsinking material of aluminum. The heat produced by rotating the magnetic field due to hot-wired coil used by the of the stator ferrite core can be dispersed by the aluminum housing (1), so to decrease the heating value of the stator ferrite core and increase whole efficiency.
According to actual testing, after applying load on the output end of the energy-saving brushless motor-kinetic generator (100) of the present invention, the actual measuring result is shown in Table 1. Therein, in a preferred embodiment of the present invention, a 20 ohm load is used as the loader, a 44 turns copper coil with diameter of 0.8 mm is used as each of the coil of each of the stator ferrite core, and magnetic strength of each of the permanent magnets is N45.
The structure of the first electric generator (110) in the energy-saving brushless motor-kinetic generator (100) of the present invention is the same as the second electric generator (130), and the difference of the actual testing output powers of structure 1 (used with the first connection device (101) and the second connection device (102)) is due to differences of magnetic field strengths of the permanent magnets or the gaps between the permanent magnets. The actual testing output power of structure 2 (used with the third connection device (103)) is larger than the output power of structure 1. It is clear that according to the arrangement of the energy-saving brushless motor-kinetic generator of the present invention can earn 1.8 times of output power, so the energy-saving effectiveness can be realized.
