中文摘要:
      为了准确模拟永磁轮毂电机的温度变化对电机运行性能的影响,课题组提出了一种有限元法与热网络法相结合的磁热双向耦合方法, 使用有限元法对电磁场进行仿真,用热网络法对温度场进行仿真,并将电磁场与温度场相耦合,反复循环迭代,直至生成稳定的电磁场及温度场。应用磁热双向 耦合法对轮毂电机样机进行分析,并与磁热单向耦合仿真结果进行对比。在电机额定工况下测得电机实际温升,仿真结果与实验结果相近,同时双向耦合的误差 率低于单向耦合。课题组提出的方法能较为准确地仿真永磁轮毂电机的温度变化。
英文摘要:
      In order to accurately simulate the effect of temperature change of permanent magnet in wheel motor on motor performance, a magneto thermal mutual coupling method combining finite element method and thermal network method was proposed. The electromagnetic field was simulated by the FEM, the temperature field was simulated by the thermal network method. The electromagnetic field was coupled to the temperature field and iterated repeatedly until the stable electromagnetic field and temperature field were generated. This magneto thermal two way coupling method was used to analyze the in wheel motor prototype and compared with the magneto thermal one way coupling simulation results. Under the rated condition of the motor, the actual temperature rise of the motor was measured, the simulation results show similarity to the experimental results. At the same time, two way coupling error rate is lower than the one way coupling. The results show that the proposed method can simulate the temperature change of the permanent magnet in wheel motor accurately.
