Abstract: A motor includes a rotor and a stator. The rotor includes a plurality of magnets, which function as first magnetic poles, and salient poles, which function as second magnetic poles. A ratio X1:X2 of a quantity X1 of magnetic pole portions of the rotor, which is the sum of the quantity of the magnets and the quantity of the salient poles, and the quantity X2 of slots is 2n:3n (n being a natural number). The sum of a magnetic pole occupying angle θ1 of the magnet and a magnetic pole occupying angle θ2 of the salient pole is 360°. The magnetic pole occupying angle θ1 is set in a range of 180°

Abstract: A rotor includes a first rotor core, a second rotor core, a field magnet, and an auxiliary magnet. The first rotor core includes a first core base and a plurality of first hook-shaped poles. The second rotor core includes a second core base and a plurality of second hook-shaped poles. The first and second hook-shaped poles are alternately arranged in a circumferential direction of the rotor. The field magnet is arranged between the first and second core bases in an axial direction. The field magnet cause the first hook-shaped poles to function as first poles and the second hook-shaped poles to function as second poles. The auxiliary magnet includes at least two interpolar magnet portions, which are integrally formed. Each interpolar magnet portion is arranged in a void between the first hook-shaped pole and the second hook-shaped pole and magnetized in the circumferential direction.

Abstract: This motor includes a two-layer rotor, a two-layer stator and a control unit. An A-phase rotor includes a pair of rotor cores and a field magnet. A B-phase rotor includes a pair of rotor cores and a field magnet. An A-phase stator includes a pair of stator cores and an A-phase winding. A B-phase stator includes a pair of stator cores and a B-phase winding. The control unit controls an A-phase input voltage applied to the A-phase winding, and a B-phase input voltage applied to the B-phase winding. The relative arrangement angle of the A-phase stator and the A-phase rotor relative to the B-phase stator and the B-phase rotor is set to an electrical angle of 90 degrees. The control unit applies a leading phase angle to the basic voltage waveforms of the A-phase input voltage and the B-phase input voltage, to set the energization width to at most 180 degrees.
