摘要： In a double-stator motor has a rotary shaft, an annular rotor is coupled with a rotary shaft. First and second three-phase stators are arranged inside and outside to the rotor in the radial direction and formed to generate first and second rotating magnetic fields in response to three-phase currents, respectively. The rotor has an even number of segment poles made of soft magnetic material and arranged mutually separately at positions of the rotor. The positions are equally distanced apart from the rotary shaft in the radial direction and in the circumferential direction. Each of the first and second three-phase stators has magnetic poles which are the same in the number of poles as the segment poles and the magnetic poles are positioned such that magnetomotive forces from the magnetic poles are faced to each other between the magnetic poles of the first and second three-phase stators.

摘要： A stator includes a stator-core having slots and teeth, and a back-yoke having convex and concave portions. The convex portions are partially inserted into the slots, and the concave portions receive the teeth. The teeth include tip portions whose circumferential widths become larger along a radial direction from the inside to the outside of the stator. The back-yoke includes convex portions whose circumferential widths become larger along the radial direction from the outside to the inside of the stator.

摘要： In a reluctance rotary electric machine, a movable part is arranged opposing part of an alignment of a plurality of stator poles to be movable in a predetermined direction. In the movable part, at least one pair of salient poles is configured to magnetically couple to the excited at least one first pair of the plurality of poles so as to form a first magnetic flux in loop thereamong. A segment magnetic-path portion is arranged to be magnetically separated from the at least one pair of salient poles. The segment magnetic-path portion works to magnetically couple therethrough between the at least one second pair of the plurality of stator poles so as to form a second magnetic flux in loop thereamong. The first magnetic flux and second magnetic flux create a reluctance force to move the movable part in the predetermined direction.

摘要： In a SPM synchronous motor has a rotor and a stator, a permanent magnet is divided to magnet parts magnetized in a diameter direction of the rotor and serve as rotor magnetic poles. The rotor magnetic poles are alternately arranged along a circumferential direction of the rotor. The rotor core has a plurality of salient poles made of soft magnetic material. Each salient pole projects from the circumferential surface of the rotor core toward a gap between the rotor and the stator, and is placed at a central part of the corresponding magnet part in the circumferential direction. This structure increases a magnitude of a d-axis inductance Ld and enhances the effects obtained by performing a weakening magnetic flux control using a negative d-axis current Id during a high speed rotation of the motor within a power source voltage limiting range.
