The shaded-pole induction motor is popular because of its simplicity and long life. This motor contains no start windings or centrifugal switch. It contains a squirrel-cage rotor and operates on the principle of a rotating magnetic field created by a shading coil wound on one side of each pole piece. Shaded-pole motors are generally fractional-horsepower motors used for low-torque applications such as operating fans and blowers.
