stator coiling and pole pieces

摘要

Disclosed is a stator (600) of an induction motor, the induction motor comprising: a stator (600) provided with a main winding coil (620) and an auxiliary winding coil (630) at a plurality of slots (611) formed at a body (610) of the stator (600); an induction rotor (300) rotatably inserted into the stator (600); and a magnet rotor (300) rotatably inserted between the stator (600) and the induction rotor (300). Coil spans (P1,P2), are different thus have an increased counter electromotive force induced in the main winding coil (620), thereby enhancing efficiency of the motor. <IMAGE>
