Abstract
The utility model provides a stator structure for a single-phase induction motor employing concentrated windings. The stator structure comprises a stator provided with stator teeth which are wound with concentrated main windings and concentrated auxiliary windings in an alternative manner. The tooth width Wm of the stator teeth wound with the concentrated main windings is unequal to the tooth width Wa of the stator teeth wound with the concentrated auxiliary windings.
