摘　　要：应用高等数学知识,对三相异步电动机和单相异步电动机在脉振磁场中会产生"自转",而与单相异步电动机工作原理非常相似的交流伺服电动机却不会产生"自转"的原因进行了详尽的说明。Higher mathematics knowledge was applied to state why three-phase asynchronous motor and single-phase asynchronous motor was able to autorotate in the pulsating magnetic field while AC servo motor,operating principle of which was similar to that of single-phase asynchronous motor could not autorotate.

关 键 词：“自转” 脉振磁场 异步电动机 交流伺服电动机
