Alexa Controlled Blinds Manufacturers introduces that shaded pole motors are the simplest one of unidirectional AC motors, usually using cage-shaped chute cast aluminum rotors. It is divided into salient pole shaded pole motor, hidden pole shaded pole motor according to the different structure of stator.

The shape of the stator core of the salient-pole shaded pole motor 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, namely shaded pole windings. The concentrated winding on the salient poles serves as the main winding.

The stator core of the hidden pole shaded pole motor is the same as that of the ordinary single-phase motor. Its stator winding adopts distributed winding, and the main winding is distributed in the stator slot. The shaded pole winding does not need to short-circuit the copper ring, but is wound with thicker enameled wire Distributed windings (short-circuit after being connected in series) are embedded in the stator slots (approximately 2/3 of the total number of slots), acting as an auxiliary group. The main winding and the shaded pole winding are spaced at a certain angle.

When the main winding of the shaded pole motor is energized, the shaded pole winding will also generate an induced current, which causes the magnetic flux of the part of the stator pole covered by the shaded pole winding and the uncovered part to rotate in the direction of the covered part.
