异步电动机轻载节能的研究

Study on Energy-Saving in Asynchronous Motor at Light Load

异步电动机在轻载运行时，效率都较低。文章通过调节电机端电压的方法，使异步电动机轻载运行时，效率提高，并能降低异步电动机的起动电流，平稳起动，从而达到节约电能与延长电动机使用寿命的目的。

Almost asynchronous motors are not efficient whenrunning in the condition of light load. In this paper, the authorintroduces an effective method by regulating the terminalvoltage on the asynchronous motor which runs in thecondition of light load to raise the efficiency of the motor, toreduce the steding current, and to make the process of startingstable. As a result, the purpose of saving energy andprolonging the motor's life has been achieved.
