Abstract: This passage mainly discussed a low cost, low noise energy efficient about single-phase plastic motor, segmented core design and processing technology. The segmented core not only significantly reduced the enameled wire usage, but also increased the utilization of silicon steel sheet. Supported by reasonable positive / anti- nested high speed impact, automatically stack buckle, bulls winding, automatically into a round hoop innovation process, can greatly improve the production efficiency of the core and motor. Through the stator teeth on the virtual cogging design, the rotor “V” shaped chute innovation design, one end of the cover with the stator plastic molding process, also can effectively improve and reduce motor noise. Theory and actual production proved this kind of core design and manufacturing process can improve the quality and production efficiency reducing the material and manufacturing costs of the motor.
