Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a stator assembly, a motor and a method for manufacturing the stator assembly. Background technique [0002] Shaded pole motors are single-phase asynchronous motors. Because of their simple structure and low cost, they are widely used in small household appliances with low power, such as small desk fans, small fans, heaters, and low-power purifiers. However, when this kind of motor is running, the magnetic field generated by the fission of the short-circuit ring is relatively large in ellipticity, which leads to defects such as low performance efficiency, high noise, poor starting, and narrow speed regulation range of the motor. [0003] Single-phase capacitor-operated asynchronous motors are also widely used in small household appliances. Compared with shaded pole motors, single-phase capacitor-operated asynchronous motors are generally applied to small household app...

AI Technical Summary

Problems solved by technology

The stator of this motor mainly adopts the winding method of distributed winding, and the operating magnetic field is close to a circle, so that this motor is superior to the shaded pole motor in terms of performance efficiency, starting torque and noise, however, the material cost of this motor is high , the production process is complicated, and it is prone to problems such as disconnection, inter-turn short circuit, breakdown, etc.
