Abstract

See full text

A consequent-pole motor comprises a rotor and a stator sleeved outside the rotor. The rotor comprises a plurality of permanent magnetic poles evenly spaced along a circumferential direction of the rotor. A plurality of stator teeth is disposed on an inner periphery of the stator along a circumferential direction of the inner periphery. A permanent magnetic pole of the rotor comprises a first permanent magnet mounting groove and a second permanent magnet mounting groove disposed sequentially from outside to inside along a radial direction of the rotor. A first layer permanent magnet is disposed in the first permanent magnet mounting groove, and a second layer permanent magnet is disposed in the second permanent magnet mounting groove. According to the motor, permanent magnets distributed in multiple layers are used, so that the magnetic resistance torque of the motor can be improved, which may increase reluctance torque, thereby increasing electromagnetic torque.
