A motor has stator windings arranged on a circumference of a stator, a rotor with rotor magnetic poles provided by N- and S-poles, and rotor windings arranged in a circumferential direction of the rotor magnetic poles. Multiple-phase currents are supplied to the stator windings. A current is supplied to rotor windings. The multiple-phase currents include torque current components, which are arranged to be opposite in directions to torque current components of the current. By this mutually opposite-directional current arrangement, a magnetomotive force based on a sum of both torque current components becomes a local minimum. It is possible to reduce influence of the torque current components on the field magnetic fluxes of the motor. In the motor, circumferential magnetic flux components can be collected to an airgap and a portion therearound, so that a larger amount of torque can be obtained, and constant output control can be performed more easily.
