| Abstract: | FEA(Finite Element Analysis)model of a three-phase asynchronous traction motor has been established for temperature field analysis.The thermal source of the motor,the equivalent coefficient of heat conductivity for stator coil and coefficient of heat radiation in the air duct and airgap by forced air circulation are analyzed.With application of Ansoft FEM(Finite Element Method)software,the temperature field simulation of this motor is accomplished,then the distribution graphs of this motor under no-load operation and rated operation are presented.The temperature of some particular points are demonstrated.Simulation results are compared and studied. |
