当前国内外交流调速的迅速发展,有取代直流调速的趋势。为此,本文论述了近代交流调速拖动的特点,综述了国内外近代交流调速的发展动向。可作为厂矿技术人员,科研人员和教学人员,对各种交流调速和控制方式以及对电子元器件、变频装置、微机、电机试制和科研、教学更新及其节能的主要技术方向提供有价值的参考。
At present, the rapid development of AC speed regulation at home and abroad has the tendency of replacing DC speed regulation. To this end, this article discusses the characteristics of modern AC speed dragging, summarizes the recent development of AC speed regulation at home and abroad. It can be used as the technical staff, researchers and teaching staffs of factories, mines and mines to provide valuable information on various AC speed regulation and control methods as well as the main technical directions for the electronic components, frequency conversion devices, microcomputer, motor trial and research, teaching renewal and energy saving reference.
