Shaded Pole Induction Motors – Working and Construction Shaded pole motor is a split-phase type single phase induction motor. The shaded pole motor is very popular for ratings below HP (~ 40 W) because of its extremely simple construction. It has salient poles on the stator excited by a single-phase supply and a squirrel cage rotor.  · Working Principle of a Single Phase Induction Motor A Single Phase Induction Motor consists of a single phase winding which is mounted on the stator of the motor and a cage winding placed on the rotor. A pulsating magnetic field is produced, when the stator winding of the single-phase induction motor shown below is energised by a single phase supply.  · Working of Shaded Pole Motor. In the core, when a single phase is applied an alternating flux is generated. This flux links with the shaded coil in fraction amounts. Then voltage gets induced in the coil due to the variation in the flux linking. Hence, the shaded portion is short-circuited due to which it produces the circulating current in it. In such a way, the direction is opposing the main flux.

Single Phase Motors

 · Working Principle of a Single Phase Induction Motor A Single Phase Induction Motor consists of a single phase winding which is mounted on the stator of the motor and a cage winding placed on the rotor. A pulsating magnetic field is produced, when the stator winding of the single-phase induction motor shown below is energised by a single phase supply.  · The shaded pole motor is simply a self-starting single-phase induction motor whose one of the pole is shaded by the copper ring. The copper ring is also called the shaded ring. This copper ring act as a secondary winding for the motor. The shaded pole motor rotates only in one particular direction, and the reverse movement of the motor is not possible.  · Working Principle of Shaded Pole Induction Motor: When a single-phase a.c. supply is given to the stator winding.
