摘要: 研究一种混合充磁式磁齿轮复合电机的温度场，通过对磁齿轮复合电机仿真得到电机铜耗、铁耗以及涡流损耗. 将其结果设置为温度场仿真的热源，对简化的磁齿轮复合电机模型进行瞬态热分析，得到混合充磁式磁齿轮复合电机各部分温度场分布及温度随时间的变化情况. 搭建试验平台进行温度测试，由计算、仿真、试验得到电机各部分随时间变化的温升曲线可知：磁齿轮复合电机内最高温度点在定子绕组部分，温度在安全范围内，不会对电机造成影响.Abstract: The temperature field of a hybrid magnetizing magnetic gear compound motor, the copper, iron and eddy current losses of the motor were obtained by simulation of the magnetic gear compound motor, and the results were set as the heat source of temperature field simulation, and the transient thermal analysis of the simplified magnetic gear compound motor model was carried out. The temperature field distribution and temperature variation with time of the hybrid magnetizing magnetic gear composite motor were obtained. By setting up an experimental platform for temperature test, the temperature rise curve of each part of the motor with time change was obtained through calculation, simulation and test. It can be seen that the highest temperature point in the magnetic gear composite motor is in the stator winding part, and the temperature within the safe range, which will not affect the motor.or.
