Abstract
A single phase motor includes an excitation part and an armature part. The excitation part includes N magnets that result in 2N magnetic poles being formed on the excitation part, and the armature part includes 2N tooth portions forming 2N pole portions, where N is an integer greater than one. The present invention further provides a rotor for the single phase motor. The present invention allows each magnet to be fully used, reduces the number of the magnets used in the single phase phase and the workload during motor assembly, as well as reduces the motor fabriction cost.
Claims19
