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： A full-pitch winding switched reluctance motor is provided. In this motor, one set of current components are estimated, which electromagnetically act on only one set of stator poles for one phase. Based on the estimated one set of current components, current components for respective three phases are controlled, resulting in accurate current control with no electromagnetic interactions with other phases. This current control allows a control circuit to be made compact, and a motor with effective field means can be provided.

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.

摘要： An A-phase brushless motor, where A is an integer greater than or equal to 2, includes a stator and a rotor. The stator has q stator poles, where q is an integer greater than or equal to A. The stator poles form S stator pole sets each consisting of A stator poles each of which corresponds to one of A phases, where S is an integer equal to (q/A). The rotor has p rotor poles, where p is an integer greater than or equal to 2, and is so arranged that the rotor poles face the stator poles. Further, in the brushless motor, p≧q, and the stator poles are arranged in a circumferential direction of the motor such that a difference in electrical angular position between any adjacent two of the A stator poles in each of the S stator pole sets is equal to (360°/A).
