Abstract: A rotor with four axially stacked rotor cores, and a plurality of field magnets interposed between them. Each rotor core includes a rotor-side claw-shaped magnetic pole. Each rotor-side claw-shaped magnetic poles are respectively extending from and formed on each rotor core at equal angle intervals. Tip end surfaces of the first and third rotor-side claw-shaped magnetic pole abut against or are closely opposed to each other axially. Tip end surfaces of the second and fourth rotor-side claw-shaped magnetic poles abut against or are closely opposed to each other in the axial direction. The plurality of field magnets are magnetized in the axial direction such that the field magnets causes the first and third rotor-side claw-shaped magnetic poles to function as first magnetic poles, and cause the second and fourth rotor-side claw-shaped magnetic poles to function as second magnetic poles.

Abstract: A motor includes a rotor and a stator. The rotor includes a first rotor core including a plurality of first claw-like magnetic poles, a second rotor core including a plurality of second claw-like magnetic poles, and a magnetic field magnet arranged between the first and second rotor cores. The first and second claw-like magnetic poles are alternately arranged in a circumferential direction. The magnetic field magnet causes the first and second claw-like magnetic poles to function as magnetic poles different from each other. The stator includes a first stator core including a plurality of first claw-like magnetic poles, a second stator core including a plurality of second claw-like magnetic poles, and a coil section arranged between the first and second stator cores. The stator is configured to cause the first and second claw-like magnetic poles of the stator to function as magnetic poles different from each other and switch polarities of the magnetic poles on the basis of energization to the coil section. At least ones of the claw-like magnetic poles of the rotor and the claw-like magnetic poles of the stator are formed in a shape in which circumferential centers of distal end portions are shifted in the circumferential direction with respect to circumferential centers of proximal end portions.

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 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.
