摘要
分析异步电动机能耗产生的原因及节能的途径，并介绍了一种自动节能控制装置．运行试验表明，这种自动节能控制装置在电机轻载的情况下，能有效地节约电能，具有较高的应用价值。
Discuss the causes of energy consumption of induction motors and the way of energy saving. In addition, introduce an automatic energy saving set. The running test indicates that this set can save electric energy efficiently in the lightly loaded state, and is of greater use value.
