Abstract

Abstract

In order to solve the problems of heat dissipation difficulty and high temperature of end windings in the operation of electric vehicles, a new type of axial U-shaped water channel cooling structure design was proposed by taking an external rotor hub motor of electric vehicles as the research object. Firstly, the magnetothermal coupling simulation model of the hub motor was established, the temperature field distribution of the motor was obtained through the motor loss analysis, and the design and fluid-thermal coupling analysis of the axial U-shaped waterway were carried out. The results show that the use of U-shaped cooling channel could effectively improved the high temperature inside the motor, especially the high temperature problem of the end winding, and the temperature rise was reduced by 28.7%.
