Abstract: A motor includes a first, second, and third motor unit. First, second and third rotors each including a first and second rotor core and a field magnet. The first and second rotor cores include respectively first and second rotor core bases and a plurality of first and second claw magnetic poles that are arranged alternately along a circumferential direction of the motor. The field magnet causes the plurality of first claw magnetic poles and the plurality of second claw magnetic poles to function as different magnetic poles. Each of first and second stators including pluralities of first claw magnetic poles and second claw magnetic poles alternately arranged along the circumferential direction of the motor. The second stator core having a coil section.

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.
