摘要
针对企业电机运行效率低,电能浪费严重的问题,分析了电机节能的原理,介绍了电机常用的节能技术与方法。主要包括电机的选型、提高功率因数、调速节能、结构改造等,并着重介绍了目前比较先进的电机节能技术一变频调速节能的原理、方法及应用。
Against the phenomenon of low operational efficiency of electric motors and serious loss of electric power in the enterprises, the commonly used energy-saving technology including correct selection of motors, increasing power factor, speed-regulation and construction rebuilding was introduced. Among them, the principle, method and application of the advanced energy-saving method, frequency-conversion, was focused.
