Temperature Field Analysis of Traction Motor Based on Magnetic-thermal bidirectional Coupling
In order to explore the temperature rise of traction motor,this paper took a large mine electric wheel traction motor as the research object,and established a finite element model of three-dimensional flow and heat transfer coupling solution of the motor.The basic assumptions and corresponding boundary condi-tions were given.The magnetic-thermal bidirectional coupling method was used to simulate the electromag-netic field and temperature field of the motor.On this basis,the temperature field distribution characteristics of the motor under low-speed full-load conditions were analyzed.The accurate analysis of the temperature field characteristics of the motor can be realized by using this analysis method,which is helpful to the rea-sonable design of the cooling system of the motor,and provides a theoretical basis for the accurate calculation of the comprehensive physical field of the higher power motor.
