【摘要】 在工业生产中,尤其在机加工行业,一些电动机在多数情况下处于空、轻载运行,造成了能源的不必要浪费。本文论述了异步电动机空、轻载的运行状况,分析了通过自动检测电压与电流的相位差角的大小来适当降低异步电动机端电压来达到节约能源的可行性,并对采取的方案进行了总体设计。更多还原

【Abstract】 In industry production,some electric motors work in empty loading or light loading so that much power is wasted.This paper firstly discusses the working process of electric motors out of step;secondly it analyzes the feasibility of saving power by examining automatically phase difference of voltage, thirdly the adopted plans are designed.更多还原
