摘要： A torque generator includes a full-pitch winding reluctance motor provided with three-phase or more coils which are composed of full-pitch windings, and a control unit therefor. The control unit controls currents supplied to the respective phase coils such that the coil for a first phase designated among the phases is first started to be current-supplied and then the coil for a second phase designated among the phases is started to be current-supplied during the current supply to the coil for the first phase. The control unit decreases an amount of the current supplied to the first coil immediately before starting the current supply to the second coil and to reinstate the amount of the current supplied to the first coil in response to starting the current supply to the second coil.

摘要： In a motor, a stationary member is provided with a number M (M is a positive integer) of first poles within 360 electrical degrees at spaces therebetween. A plurality of windings are at least partly wound in the spaces, respectively. A movable member is movably arranged relative to the stationary member and provided with a number K (K is a positive integer) of second poles. The number K of second poles is different from the number M of first poles. A unidirectional current supply unit supplies a unidirectional current to at least one of the windings so as to create an attractive force between at least one of the first poles and a corresponding at least one of the second poles to thereby move the movable member relative to the stationary member.

摘要： An AC motor is provided. In the AC motor, there are M pieces (M is an integer of 3 or more) of stator pole groups SPG are arranged in a rotor axis direction, where each of the stator poles groups is composed of a plurality of stator poles which are for the same phase and arranged in a circumferential direction of the motor. Between the stator pole groups SPG, “M−1” pieces of annular windings WR are arranged which allow one-way current to flow therethrough. The windings WR are arranged such that the directions of current passing therethrough are reversed in turn in the rotor axis direction. The stator pole groups SPG are excited to generate magnetic fluxes φG directed in a one way. The excited directions of the magnetic fluxes φG are reversed in turn in the rotor axis direction.
