Stator Winding. A stator winding is simply the stationary winding in an electric motor, either for rotary or linear. The stator in an AC motor is a wire coil, called a stator winding, which is built into the motor. When this coil is energized by AC power, a rotating magnetic field is produced.The stator windings have a very low resistance and the winding is also insulated from the frame.tator Winding.
