Thermal analysis of high speed permanent magnet brushless DC motor

  • 摘要: 为了解决高速永磁无刷直流电机温升过高带来的磁性能降低及绕组绝缘破坏等问题,对高速电机的温度分布及改进措施进行了一系列研究.采用集中参数法建立了电机热网络数学模型,推导出电机损耗、热导和温度之间的解析方程;建立了基于ANSYS/Workbench的电机三维有限元模型,对其进行稳态热分析,从而得到电机整体的温度分布,验证了电机热网络模型的正确性;提出了改变转子护套材料及电机轴打孔两种措施.分析结果表明:改进后的电机转子部分温度有了明显降低,其中护套温度降低了约34℃,永磁体约54℃,解决了电机的局部温度过高问题.
