Abstract:  In application of the thermal function of ANSYS FEM software the 1250kW electrically excited synchronous motor was simulated. Upon that temperature distribution graphs of stator and rotor were showed. The relation of winding temperature to losses was analyzed and the method of detecting winding temperature without machine senior was provided. Simulation results prove that this method is valid. The works have the benefit for temperature detection of motors.
