Temperature field analysis of motor with oil cooling based on CFD

Increasing the input current is an important way to increase the power density of the motor. However, the increase in current is limited by the heat dissipation capacity of the motor. In this paper, an in-slot direct oil cooling system is proposed, which enhances the heat dissipation capacity of the motor. With direct oil cooling the motor can work stably at high current density. Temperature field analysis of the motor with oil cooling is completed based on CFD.
