The Polyphase Induction Motor

Fig. 1. Physical construction of the squirrel-cage induction motor: (a) cross section showing stator and rotor, (b) rotor construction. 1. Basic operation of the induction motor As previously shown, the phase displacement between the voltages applied to the stator windings produces a travelling MMF or rotating magnetic field in the uniform air gap.
