摘要:
A motor including a stator and a rotor is disclosed. The rotor includes a first unit and a second unit. The first unit includes an N-pole first magnet and an S-pole second magnet. The first and the second magnets are alternately arranged along a circumferential direction of the rotor at equal angular intervals to form magnetic pole portions. The second unit includes an N-pole or S-pole third magnet and a salient pole arranged in the rotor core. The salient pole functions as a magnetic pole that differs from the third magnet. The third magnet and the salient pole are alternately arranged along the circumferential direction of the rotor to form magnetic pole portions. The number of magnetic pole portions of the second unit is the same as the number of magnetic pole portions of the first unit. The third magnet and the magnet of the first unit having the same pole as the third magnet are aligned in the axial direction of the rotor.
