电机的热分析方法与应用

Thermal Analysis Method and Application of Motor

着重介绍了3种电机热分析方法,包括类比法、等效热路法与数值解法。结合实例计算与试验数据,详细描述了每种计算方法的基本原理、计算过程、应用范围以及优缺点,提及的计算方法和内容对电机热设计具有重要的参考作用。

Three kinds of thermal analysis methods were proposed, including the analogy method, the equivalent ther-mal circuit method and the numerical method. The basic principle, calculation procedure, the application range of eachcalculation method as well as advantages and disadvantages were described in detail with the example calculation and testdata. The calculation methods and contents have important reference value for the thermal design of electrical machines.
