变频器驱动电动机的节能

Energy-saving of the Motors Driven System Fed by the Inverter

介绍了将感应电动机或永磁电动机与变频器组合成可变速控制系统,主要用于驱动风机、水泵类负荷,以实现高效率化和节能。文章对有关变频驱动电动机节能的动向、节能的实例以及对已安装好的电动机改用变频驱动时的注意点予以了介绍。

The combined speed-regulation system consisted of induction or PM motors and inverters, which was mainly used in fan, pump and etc to realize the high efficiency and energy-saving, was introduced. The develop- ment tendency of the frequency-control energy-saving mo- tor system, practical example of energy-saving application of this kind of motor and precautions during rebuilding the traditional motor into inverter-fed one were presented.
