本文简述了三相异步电动机运行中的效率、功率因数、负载率和功率的关系及各种节电措施。
According to wear and energy-saving principle of three-phase asynchronous motor, relations between pressure of motor and load are researched herein that is pressure is restrained by the load to rate.
根据三相异步电动机损耗及节能原理，研究异步电动机端电压与负载大小之间的关系：电压将受负载对转速要求的制约。
It usually estimated to determinate power saving rate to see if the motor load set used a frequency conversion device due to difficulty of data collection and the results were not quiet correct.
由于采集数据的困难，电机负载组是否采用变频装置，往往通过估算来确定节电率，其结果不准确，而且因人而异。
