| Abstract: | According to calorifics theory, a mathematical model of 3D transient temperature field for a direct driving low speed permanent magnet torque motor was established, where hypothetical and boundary conditions of the solved region were presented. Transient temperature field of the motor was calculated using 3D finite element method in the rated electromagnetic field condition. Comparison between calculation and measurement results proves that the established transient temperature field model is reasonable, which is a good reference to the temperature field calculation this kind motor. |
