Abstract
A single phase motor includes a stator and a rotor. The stator includes a stator core. The stator core includes an outer yoke and a plurality of stator teeth. Each stator tooth includes a winding portion and a pole shoe coupled to the winding portion. The rotor includes a rotor core and a plurality of permanent magnets. The permanent magnets are evenly spaced and embedded in the rotor core. An outer circumferential wall of the rotor core is an irregular cylinder and includes a plurality of spaced circular arc surfaces and transition surfaces. The starting of the single phase motor is stable and reliable. The present invention also provides a rotor for the single phase motor.
