PURPOSE:To enable various rotational-frequency/torque characteristic to be obtained, by applying a shunt field coil group on a stator plate, and by composing a stator. CONSTITUTION:A fixedly magnetized rotor 13 is firmly fitted on a motor shaft 9, and they are integrally rotated. A stator 14 is set confronted with the rotor 13, and the rotor 13 is provided with a shunt field coil group applied on a stator plate 6. The shunt field coil group consists of six sector-like shunt field coils 7a and shunt field coils 7b arranged in the space of the inner peripheral sections of the coils 7a. Current is selectively supplied to the shunt field coils 7a, 7b. |
