Description

Technical Field

[0002] A motor coil frame, also called a coil frame or a winding frame, is a structural component used to support and fix the coil in the motor. It is usually made of magnetic conductive material to facilitate magnetic conductivity and reduce iron loss. When the motor is stationary or working, the coil frame may vibrate due to external or other reasons, which may cause the copper wire wound on the coil frame to loosen, thereby reducing the power of the motor. Therefore, a motor coil frame that avoids loosening is proposed.

[0003] When the existing motor coil frame is in use, the motor coil frame may vibrate due to external vibration, which may cause the copper wire wrapped on the motor coil frame to loosen, resulting in poor connection or disconnection of the coil, thereby causing the performance of the motor to deteriorate, and the motor may be at risk of overload, overheating or damage. In addition, most of the existing motor coil frames have relatively poor corrosion resistance. When the motor is used in a relatively harsh environment for a long time, the motor coil frame may rust, thereby reducing the structural strength and stability of the coil frame. For this reason, technical improvements are urgently needed. Utility Model Content
