Abstract
A single phase permanent magnet motor includes a stator core, windings, and a permanent magnet rotor. The stator core includes an end portion and two spaced arm portions each including a connecting arm and a pole claw. Each pole claw has a long pole tip and a short pole tip, and forms a pole surface. The long pole tip of each pole claw corresponds to the short pole tip of the other pole claw with a slot opening formed there between. The slot opening causes the arc pole surface to be discontinued along a circumferential direction, and the arc pole surface is recessed inwardly to form a startup groove.
