AI Technical Summary

Technical Problem

The existing motor stator has poor heat dissipation, which leads to a decrease in motor performance, especially due to the long heat transfer path and poor oil cooling effect.

Method used

A stator structure was designed in which the windings and the stator core are separated by insulating paper. The coolant flows between the inner wall of the core slot and the insulating paper. The coolant and the windings are in close contact with each other through the insulating paper. The flow path of the coolant is optimized by multi-stage flow channels and buffer structures, which reduces the heat transfer distance and impact and improves the cooling efficiency.

Benefits of technology

It effectively improves the heat dissipation of the stator, enhances the cooling capacity of the motor, and improves the working efficiency and stability of the motor.
