AC Motors AC Induction SinglePhase & ThreePhase Motors

3Phase AC Induction Motor Construction. The AC motor consists of two main parts: the rotor and the stator. The stator is the outer shell and remains stationary. It has windings that transform the incoming electricity into a magnetic field. This causes the rotor to become magnetized in the opposite polarity and repel and rotate.
