Shaded pole motors, also called shaded pole motors, are single-phase AC motors, usually using cage-shaped skew-slot cast aluminum rotors. 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.

How to classify shaded pole motors?
There are two classifications of shaded pole motors according to their appearance, namely, salient-pole shaded pole and hidden pole-type shaded pole.
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, that is, 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 motor 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 (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.
What are the characteristics of shaded pole motors?
1. Reasonable structure design, flexible lead-out direction, and the terminal box of shaded pole motor can be installed in rotation.
2. Superior shaded pole motor performance, low noise, low vibration, high-performance protection level.
3. Numerous options to meet the needs of various users to install thermistors.
4. The optimized design has high efficiency and can produce considerable energy-saving effects.
5. Add various requirements such as dust-proof sealing ring, heating belt, oil-proof sealing ring, oil injection, special shaft extension, special flange, and so on.
What is the structure of shaded pole motors?
Shaded pole motors are mainly composed of rotor components, stator components, wire package components, bracket components, and connecting fasteners. The rotor assembly is mainly composed of a cast aluminum rotor, a shaft, a thrust washer that prevents the rotor from moving back and forth, and a gasket to adjust the amount of movement; the stator assembly is mainly composed of a short-circuit ring and the main stator core; the wire package assembly is mainly composed of a coil, a skeleton, and a lead It is composed of wiring or thermal protector and related insulating wrapping materials; the bracket assembly is divided into front bracket assembly and rear bracket assembly according to the different installation positions of the shaft extension end and the non-shaft extension end.
