| 摘 要： | 针对表面-内置式永磁转子同步电机(SIPMSM)具有结构紧凑和功率密度高的特点,准确计算SIPMSM各部件的温度分布非常重要。采用电磁场-温度场耦合分析的方法对SIPMSM的三维全域温度场进行计算。建立SIPMSM的电磁场和温度场有限元模型,分析在同步运行速度下负载和永磁体退磁对SIPMSM三维全域温度场的影响,也分析了在额定负载下运行速度对SIPMSM三维全域温度场的影响。通过仿真与实验结果的对比分析,验证了样机模型的合理性和计算结果的正确性。

| Abstract: | Aiming at the compact structure and high power density of surface-mounted and interior permanent magnet synchronous motor (SIPMSM),accurate calculation of 3-D full-domain temperature distribution for SIPMSM is very important.The coupling analysis of electromagnetic field and temperature field was adapted to calculate 3-D temperature field distribution of SIPMSM.Finite element models of electromagnetic field and temperature field were established to analyze the influences of load and permanent magnet demagnetization on 3-D full-domain temperature field of SIPMSM at synchronous speed,and the influences of various speed on 3-D full-domain temperature field of SIPMSM with rated load were also analyzed.The reasonability of prototype model and accuracy of results were verified by comparison of simulation and test. |
