Abstract: The loss model of high power density motor was studied. The way to transfer heat of the rotor is corrected which is based on the heat exchange model. The temperature field simulation model and the experiment method was established for analyzing each part of the motor temperature,obtaining the temperature distribution about rotor, stator, housing, windings and so on. Finally, different materials and different heat exchanger of rotor was comparative analyzed for further illustrating the advantages of nonmagnetic stainless steel in reinforcing the permanent magnet .
