Shaded Pole Motors. A Shaded Pole motor is an AC single phase induction motor. The auxiliary winding, which is composed of a copper ring, is called a shading coil. The current in this coil delay the phase of magnetic flux in that part of the pole in order to provide a rotating magnetic field.The direction of rotation is from the unshaded side to the shaded ring.he auxiliary winding, which is composed of a copper ring, is called a shading coil.
