The slots on the periphery of stator core of the three phase induction motor carries three phase winding or Stator winding. This three phase winding is supplied by three phase AC supply. The three phases of the winding are connected either in star or delta depending upon which type of starting. This phenomenon is called as crawling of an induction motor. This action is due to the fact that, flux wave produced by a stator winding is not purely sine wave. Instead, it is a complex wave consisting a fundamental wave and odd harmonics like 3rd, 5th, 7th etc. course of learning the design procedure of induction motor.
