As shown in FIG. 1, six permanent magnets 101, 102, 103, 104, 105, and 106 are installed so as to be rotatable together with the shaft, and the rotary shaft is rotatably attached to a bearing (not shown). Two electromagnets 201 and 202 are provided outside the permanent magnet, and the electromagnet is fixed by a fixing means not shown. Six coils 301, 302, 303, 304, 305, and 306 are provided around the permanent magnet, and the coils are fixed by unillustrated fixing means. Two rotary discs 401 and 402 are mounted on the shaft and two electromagnet actuating and non-actuating devices 501 and 502 using a photointerrupter and other electronic components are used to actuate and deactivate the electromagnets do. Two secondary batteries 601 and 602 are used to supply a direct current to the electromagnet.

Rotating discs 1, 2 (401, 402) are mounted on the shaft, each rotating disc repeating the process of passing light through 2.5 degree intervals and blocking for 7.5 degree intervals 6 times, . This 120-degree interval process is repeated as the rotating disc rotates. The rotating disk-1 (401) is used to connect and disconnect the electromagnet-1 (201) and the secondary battery-1 (601) 1 is set such that light of the photo interrupter-1 11 starts passing when the electromagnet-1 201 and the permanent magnet-1 101 face each other. The rotating disk-2 (402) is used to connect and disconnect the electromagnet-2 (202) and the secondary battery-2 (602) When the electromagnet-2 202 and the permanent magnet-1 101 face each other, the light of the photo-interrupter-2 31 starts to pass.

The electromagnet actuating / non-actuating apparatus-1 (501) activates and deactivates the electromagnet-1 (201). As shown in FIG. 3, when light of the photo interrupter-1 11 is passed, the N channel FET (Field Effect Transistor) -1 is turned on and the electromagnet-1 201 is turned on from the secondary battery- And the electromagnet-1 201 is operated. When the light of the photo interrupter-1 11 is interrupted, the N channel FET-1 12 is turned off, and electricity does not flow from the secondary battery-1 601 to the electromagnet- When the electricity is cut off from the secondary battery 1 (601) to the electromagnet-1 (201), a back-emf occurs in the electromagnet-1 (201). This counter electromotive force is blocked by the diode-1 13 from flowing to the anode of the secondary battery-1 601 and stored in the capacitor-1 17 after passing through the diode-2.

When the light of the photo interrupter-2 31 is interrupted, the N channel FET-2 32 is turned off, and electricity does not flow from the secondary battery-2 602 to the electromagnet- When the electricity is cut off from the secondary battery-2 602 to the electromagnet-2 202, a back-emf occurs in the electromagnet-2 202. This counter electromotive force is blocked by diode-5 (33) from flowing to the anode of secondary battery-2 (602) and stored in capacitor-2 (37) through diode-6 (34). When the voltage of the capacitor-2 37 becomes the breakdown voltage of the diode-7 35 which is the zener diode, the electric power stored in the capacitor-2 37 passes through the diode- And the secondary battery 2 (602) is charged.

When the permanent magnet -1 101 reaches the position facing the electromagnet-1 201 as shown in FIG. 1, the light of the photo interrupter-1 11 is passed by the rotary disk-1 401.
