摘要： A single phase permanent magnet motor includes a stator and a rotor. The stator includes a stator core with windings. The stator core includes a yoke and claw-poles. Each claw-pole forms an arc pole face which is an involute curved face. All arc pole faces cooperatively define a space for receiving the rotor. A gradually changing uneven air gap is defined between the arc pole faces and the rotor. When the motor powers off and stops, the pole axis of the rotor is offset from the central axis of the claw-poles by a certain angle to avoid the rotor to stop at a dead point position, thus facilitating next startup of the motor.
