三相异步电动机的应用是十分广泛的，在工农业生产和军事、科技等方面处处离不开三相异步电动机。例如工厂里的机械设备绝大多数由三相异步电动机提供动力，煤矿的引风机、卷扬机、吊车，加工用的车床以及农村用的各种水泵、碾米机、制粉机等都是采用三相异步电动机来驱动的，它给我们的生产和生活带来了很大的方便,The application of three-phase asynchronous motor is very broad, and can not be separated from the three-phase asynchronous motors in industrial and agricultural production and military, science and technology everywhere. For example, the vast majority of the factory' s machinery and equipment by the three-phase asynchronous motor powered, induced draft fan coal mine hoist, crane, processing lathe as well as in rural areas with a variety of pumps, rice mills, milling machines and other three phase asynchronous motor driven, it brought a lot of convenience to our production and life
