Working Principle of Shaded Pole Motor

When power is supplied to the stator, magnetic flux is induced in the main part of the poles. This flux induces a voltage in the shielding coil. This acts as a secondary winding. According to Lenz's law, the direction of current should be opposite to the magnetic flux entering the coil. This acts as the secondary winding of the transformer.

In the core region, when a single phase is applied, alternating flux is generated. This flux is fractionally linked to the shadow coil. Then, a voltage is induced in the coil due to the change in flux linkage. Therefore, the shaded portion is short-circuited, thereby generating a circulating current therein. In this way, the direction is opposite to the main flux.

The main core flux is opposite to the flux produced by the circulating current in the ring. Therefore, magnetic flux is induced in the shaded and unshaded parts of the motor with a phase difference that lags behind the unshaded pole flux. There is also a spatial displacement of less than 90 degrees between the shadow ring magnetic flux and the main magnetic flux.

Motor flux. Due to this spatial displacement, a rotating magnetic field is generated, which generates torque on the cage motor. To obtain the reversal of the direction of rotation we have to provide two shading coils.

Definition of Shaded Pole Motor

A shaded pole induction motor is a simple single-phase induction motor that is self-starting with one pole shaded by a copper ring. Another name for the copper ring is the shadow ring, which acts as the secondary winding of the motor. It only rotates in one direction, and especially torsional torque is impossible. The power induction losses of this motor are very high and the power factor is also very low. The starting torque induced in the motor is very low. For these reasons, it is inefficient. At this point, it has a low power rating. It is also a salient pole split phase motor.
