A poly phase induction motor consists of two major parts, the stator and rotor. When stator is excited with . a.c. voltage, rotating field is set up. This field produces an EMF in the rotor winding by mutual induction principle, which in turn circulates current when the rotor is short circuited. .. DC MACHINES.
