交流异步电动机轻载降压节能分析

Research on Reducing Voltage and Saving Power for Asynchronous Motors Working in a Little Loading

基于近几年来全国范围内大量缺电,造成煤炭资源紧缺的现状,讨论了电动机降压节能原理及降压以后对电动机性能产生的影响,探讨了现有节能方法中的利与弊,并从理论上分析了降压节能的最佳系数。通过分析认证了降压节能具有合理性,具有很实用的价值。

In recent years, the whole country is in short of the electricily and coal badly. Based on the status, this paper discusses the stepping down-energy saving principle of the electric motor and the influences on the electric motor after they are stepped down. And it probes into the advantages and disadvanlages of the saving energy methods. Al the same time, the best stepping down energy saving coefficienl is analyzed. The rationality of this method is validated through all the results, so it is of high value.
