摘　　要：对异步电机附加损耗产生原因及分类进行了论述,重点分析了基频漏磁附加损耗、高频谐波附加损耗以及斜槽转子横向谐波电流的产生原因,最后提出了降低附加损耗的一些有效措施。Cause and classification of the additional loss of asynchronous motors are described,among which,analysis on the additional loss of the magnetic flux leakage under basic frequency and that of the high frequency harmonic are focused,as well as analysis onto the generation of transverse harmonic current of skewed slot rotor.Finally,some effective measures to reduce the additional loss are put forward.
