煤矿主扇电机采用双馈电机节能 ,节能效果显著 ,并能从根本上解决主扇工作效率低、大马拉小车现象 ,同时可以提高功率因数 ,减少谐波对电网的污染。
The main fan motor of coal mine saves energy by using doubly-fed motor, and has obvious energy-saving effect. It can fundamentally solve the problem of low efficiency of main fan and big car pulling phenomenon, meanwhile, it can increase power factor and reduce pollution of power grid.
