<p>The present invention provides a single phase brushless motor. The single phase brushless motor includes: a stator and a rotor which rotates about the stator. The rotor has a plurality of permanent magnets. The stator includes a stator core and a wire which is wound on the stator core. The stator core includes an external ring part, an internal ring part, and a connection part which is connected to the internal ring part and the external ring part. The wire is wound on the connection part. The rotor is contained inside the internal ring part. The internal ring part and the rotor form a uniform air gap. A recess is formed on the internal surface of the internal ring part between each pair of connecting parts which the recess is adjacent to. The center of each recess deviates from the center line symmetrical to the pair of the connection parts.</p> |
