The design of cooling structure and the research of temperature rise for perma-nent magnet traction motor are of great significance to the safe and stable operation of trains.Taking a fully-enclosed permanent magnet traction motor for urban rail as an example,this pa-per researches the fluid-structure coupling heat transfer calculation of the motor by whole ma-chine model,and calculates the flow condition of cooling medium and the distribution of tem-perature field for whole motor.According to the simulation results,this paper optimizes and im-proves the cooling structure,carries out the verification and calculation by simulation,and fi-nally compares the simulation results with experiment results.The research results show that a-dopting the fluid-structure coupling heat transfer calculation can understand the complex flow condition of the cooling medium and accurately calculate the temperature field of the motor.The temperature rise of the motor with the optimized cooling structure is more reasonable.
