PURPOSE:To enable high torque and high speed to be obtained, by a method wherein a high DC power source accommodated to output torque and rotational frequency is used, and wherein the rise of exciting current is sharply performed, and wherein storage energy is circulated to the power source. CONSTITUTION:A rotor 1 has salient poles 1a, 1b..., and a rotor 2 has magnetic poles 3a, 3b, 4a, 4b.... On the magnetic poles 3a, 3b, 4a, 4b..., exciting coils 3c, 3d, 4c, 4d... are respectively fitted. On the side surface of the rotor 1, a magnet ring 14 is firmly fitted, and with the magnetic pole surface, Hall elements 14a, 14b are confronted. The scale of exciting current to the exciting coils 3c, 3d, 4c, 4d... is controlled by an inductance without energy loss, and its storage energy is circulated to a power source. |
