摘要
介绍了一种交流异步电动机的调速节能系统。该系统除对异步电动机进行闭环调速外，还具有节电功能，从而实现了调速节电运行的目的。
The paper introduces the speed modulation and energy_saving system of an induction motor.This system can not only modulate the speed of the closed circularity in an mduction motor but also saves energy.Hence it realizes the speed modulation and energy_saving operation.
