Actually,the things that the electromotor was burned-out or the electromotor works in a abnormal function was often appearance . According to the practical situation to take reasonable scheme of maintenance and select the reliable production to protect the electromotor is impotent . This article expounds the structure and the basic principle of the three phase asynchronous motor and introduced the method to solve the common faults of the electromotor . And , this article introduces the daily protection of the three phase asynchronous motor . Keywords three phase asynchronous motor principle structure common faults maintenance .  目 录 摘 要···········································································Ⅰ 绪 论···········································································1 1三相异步电动机的构造·························································2 1.1定子部分···································································· 1.2转子部分···································································· 2 三相异步电机的常见故障及处理方法········································ 2.1三相异步电动机绕组局部烧毁················································ 2.2三相异步电动机绕组接地故障················································ 2.3在对电动机通电后电动机不转，而且有嗡嗡声································ 2.4电动机过热甚至冒烟·························································· 2.5运行中电动机振
