Single phase permanent magnet motor and stator core thereof
A single phase permanent magnet motor includes a stator core, windings wound around the stator core, and a permanent magnet rotor. The stator core includes an end portion and two spaced arm portions. Each arm portion includes a connecting arm connected to the end portion and a pole claw formed at a distal end of the connecting arm. The two pole claws define a space for receiving the rotor. The pole claws surround the space and form an arc pole surface. The arc pole surface is recessed to form a startup groove located at a central axis of the pole claw. The two pole claws are spaced apart to form two slot openings there between. A line connecting the two slot openings is orthogonal to the central axis of the pole claw.
