Abstract
Description

[0002] The stator core group is wound with coils, and the wire ears are injection molded on the end face of the core group and distributed in a circular ring shape at the edge of the end face of the core group. Poor conductivity between the wire and the wire ears will cause abnormal motor power and reduced life. Therefore, good conductivity between the wire and the wire ears must be ensured during the stator processing. In the industry, the wire is wound around the wire ears, and then the wire ears are pressurized and heated to deform and weld them to the core group. At the same time, the high temperature vaporizes the paint on the coil and is squeezed out, achieving permanent connection and conduction between the wire and the wire ears.
