A single phase permanent magnet motor and a driving mechanism are provided. The motor includes a stator core, a rotor, and a winding. The rotor includes permanent magnetic poles. The stator core includes a stator yoke, n stator teeth and n auxiliary teeth. The n stator teeth and the n auxiliary teeth are alternatively spaced along a circumferential direction of the stator yoke. The winding is wound around the stator teeth. When the winding is energized, n main magnetic poles having the same polarity are produced respectively at the n stator teeth, and n auxiliary magnetic poles having a polarity opposite to the polarity of the main magnetic poles are produced respectively at the n auxiliary teeth, wherein n is a positive integer greater than 1. The motor has a greater power density and efficiency.
