Shaded Pole Motor is the simplest type of single-phase AC motors, usually using cage-shaped skew-slot cast aluminum rotor. It is divided into salient pole type shaded pole motor and hidden pole type shaded pole motor according to the different shape and structure of the 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, and each magnetic pole has one or more auxiliary short-circuit copper rings, that is, shaded pole windings. The concentrated winding on the salient pole pole 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 automatically after being connected in series) are embedded in the stator slots (about 1/3 of the total number of slots) and act 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.
The advantage of the shaded pole motor is that it has a simple structure and does not require additional windings and capacitors.
The drain pump used in the air conditioner embedded machine is a typical shaded pole motor with a low defect rate. The general fault is that the motor is dirty and blocked.
Features of shaded pole motor:
- Reasonable structure design, flexible lead-out direction, the terminal box of shaded pole motor can be installed in rotation
