摘要/Abstract

摘要： 异步电动机的无功需求与其所带负载时的工作状态有很大关系。通过分析异步电动机从空载到稳定负载时励磁电流的变化，反映出电动机不同工作方式所需的无功呈变化状态，应根据电动机的实际工作方式选择不同的无功补偿设备。

Abstract: The reactive power demand of asynchronous motor is mostly depended on the operation condition of its load. The exciting current variation of asynchronous motor from noload condition to stable onload condition was analyzed; and the analysis shows that the reactive power demand of the motor varies along with its operating mode. The reactive power compensation equipment for a motor must be selected according to its practical working mode.
