| Abstract: | The model of a three-phase asynchronous traction motor is established by finite element analysis of temperature field.The heat resource of the motor,the equivalent coefficient of heat conductivity for stator coil,and the coefficient of heat radiation in the air channels and air gap at the forced ventilation condition are analyzed.In application of Ansoft(finite element analysis software),the temperature field of this motor is simulated,then the distribution drawings of this motor(including stator and rotor) under no-load and full-load operation are presented.The temperature of some particular points is listed,and the simulation result is compared and analyzed. |
