变极双速异步电动机在球磨机中的应用

Application of Pole-change Double-speed Asynchronous Motors into the Ball Mill

介绍了目前球磨机电动机的应用状况及相关问题,阐述了变极双速异步电动机特性及节能原理,并以某水泥厂球磨机的电动机的节能改造为例,显示其节能效果。

Present application and existed problem of the ball mill motor were introduced while features and energy-saving principle of the pole-change double-speed asynchronous motor were described,furthermore,the energy-saving by the ball mill motor rebuilding in a cement factory was taken as an example to show the effect of energy-saving.
