A single phase permanent magnet motor includes a stator core and a permanent magnet rotor rotatably disposed in the stator core. The stator core includes an end portion and a pole arm extending from the end portion. The pole arm includes two connecting arms connected to the end portion and two pole claws formed at distal ends of the connecting arms. The permanent magnet rotor is disposed between the two pole claws. The rotor comprises a rotor core and a plurality of permanent magnets embedded in the rotor core, and the rotor core is made of a magnetic material.
