摘 要: 鉴于电动机匝间短路故障与定子电阻、电流和槽内导体损耗之间的定量关系,提出了电动机匝间短路温度分析有限元计算模型,研究了匝间短路位置和故障程度与电机温升之间的关系。运用有限元分析软件FEPG对电动机空载、满载及匝间短路故障后的温度场进行了仿真计算,证明该模型是正确的。 Based on the quantitative relation between inter-turn short faults and stator resistance, current, conductor loss in slots, finite element model on temperature analysis of inter-turn short faults is provided. The relationship between inter-turn short circuit faults and temperature is studied. Using FEPG simulation on motor temperature under no-load, full load and inter-turn short circuit faults is done. The results show that this modeling is correct.
