Motor Picture

The Classification of the Shaded Pole Motor

According to the shape and structure of the stator, shaded pole motors are divided into salient pole shaded pole motors and hidden pole shaded pole motors.

• Salient pole shaded pole motor: The stator core is a square, rectangular or circular magnetic field frame with protruding magnetic poles. Each magnetic pole has one or more auxiliary short-circuit copper rings, that is, shaded pole windings. The concentrated winding on the salient magnetic pole serves as the main winding.

• Hidden-pole shaded-pole motor: The stator core is the same as that of ordinary single-phase motors. The stator winding uses distributed winding. The main winding is distributed in the stator slot. The shaded-pole winding does not need short-circuiting copper rings, but is wound with thicker enameled wire. Distributed windings (short-circuit themselves after being connected in series) are embedded in the stator slots (about 1/3 of the total number of slots) and play the role of auxiliary groups. The main winding and the shaded pole winding are separated by a certain angle in space.

The Structure of Shaded Pole Motor 

• Rotor group: mainly composed of cast aluminum rotor, shaft, thrust washer to prevent the rotor from moving forward and backward, and gasket to adjust the amount of movement.

• Between stator groups: mainly composed of short-circuit ring and main stator core.

• Wire package assembly: mainly composed of coils, skeletons, lead wires or thermal protectors and related insulation wrapping materials.

• Bracket assembly: According to the different installation positions of the shaft extension end and non-shaft extension end, it is divided into front bracket assembly and rear bracket assembly.

The 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.
