Analysis of Temperature Field and Water Cooling Heat Dissipation of Wheel Motor
Due to the high heating rate and poor heat dissipation performance of the wheel motor,too high motor temperature will reduce the working efficiency of the motor and affect the working stability of the motor.In this paper,the electromagnetic simulation model of wheel hub motor established by Maxwell software is used to get the corresponding heat source loss of motor.The heat generation rate of each part of the motor and the heat transfer coefficient of the important surface of the motor are calculated by the temperature field calculation model.A double helix cooling channel structure of cooling motor is designed.The temperature field and cooling structure of the motor are simulated by Ansys software,and the distribution of temperature field before and after cooling is analyzed.The results show that the cooling structure can greatly reduce the temperature rise of the motor,and the cooling effect of the two-channel structure is better than that of the traditional single-channel structure,which has a certain reference value for the research of the heat dissipation system of the wheel motor.
