Title: MOTOR, MOTOR CONTROL METHOD AND MOTOR CONTROL DEVICE
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.
