摘　　要：电动机系统节能属十大节能工程之一。比较复杂的系统包括电动机的调速与控制装置、转动器、被拖动设备和介质的输送管网。一般用于风机、水泵传动的低压电动机数量多,采用变频调速节能效果显著;而高压电动机虽然数量少,但由于高压电动机单机容量大,一般都在数百、数千千瓦,故节能潜力更大。分析电动机节电政策、潜力及主要措施,以某钢铁厂变频调速节能改造为例,介绍变频调节的应用和效益分析。The electrical machinery system energy conserva- lion takes one of the ten big energy conservation projects. The complex system includes the electric motor velocity modulation and the control device, the electric motor, the rotation, the driven equipment and the medium transportation pipe network.Uses in the air blower, water pump transmission low tension motor quantity gc, uerally are many. The effect of using the frequency conversion velocity modulation for energy eonservation is remarkable; But high-tension nmtor although quantity are few. The paper analyzes the policies, potentials and main measures of motor energy saving. Taking iron and steel industries refonnation as example, the paper introduces the application and benefits of velocity modulation.
