Muhammad Mashood (05220) Khawaja Muhammad Abdul Rahman (04614) Mohammad Awais Zaheer (06706) Introduction • Single Phase induction motor is a type of induction motor which uses single phase AC supply to stator. • The single-phase motor stator has a laminated iron core with two windings arranged perpendicularly. Main and Auxiliary Windings.
Single Phase Induction Motor Double revolving field theory • The three-phase induction motor starting torque inversely depends on the slip • This implies that a small positive slip (0.01–0.03) generates larger torque than a larger negative slip (1.95–1.99) • This torque difference drives the motor continues to rotate in a forward direction without any external torque.

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.
