摘要
为了研究内置式永磁同步电机在不同工况及不同温度情况下永磁电机各部分的损耗,首先,基于运行参数及温度对永磁电机各损耗进行仿真,并建立基于运行参数及温度的损耗模型。在永磁电机定转子各部分预埋测温元件,采用变工况温度实验进行永磁电机温度及损耗实验。然后,结合电机导热特性及测温元件布置建立永磁电机等效热网络模型,通过永磁电机在不同工况下的温度及总损耗实验结果,采用扩展卡尔曼滤波算法对永磁电机进行各损耗的分离。最后,将分离出来的损耗与实测总损耗和计算损耗模型结果分析进行对比,验证损耗分离方法及基于工况和温度损耗模型的正确性。
In order to study the loss of each part of the permanent magnet synchronous motor(PMSM) under different working conditions and different temperatures, firstly, the losses of the PMSM are simulated based on the operating parameters and temperature, and the loss models are established.The temperature measuring components are embedded in each part of the stator and rotor of the PMSM,and the temperature and loss experiments of the PMSM are carried out by adopting the temperature test of variable working conditions. The equivalent thermal network model of the PMSM is established based on the heat conduction characteristics of the PMSM and the arrangement of the temperature measuring components. According to the results of temperature and total loss of the PMSM under different working conditions, the various losses of the thermal network model are calculated using the extended Kalman filter algorithm. Finally, the separated losses are analyzed and compared with the measured total loss and the calculated loss results to verify the correctness of the separation method and the loss model based on working conditions and temperature.
