快速错位无环流的直流电动机可逆调速系统的剖析

Analysis of Reversible Speed Regulation System of DC Motor with Characteristics of Fast Phase Stagger and Free Ring Current

本文讨论的晶闸管的错位无环流可逆直流调速系统，与常规的结构大不相同。系统主要以“软件”错位方式来实现无环流快速反向。系统的电路简单，调整方便，且性能良好，是一种工程实用系统，值得在适用的场合推广使用。

This paper presents a reversible DC speed regulation system that has great difference in constructions with the normal ones.The free ring current and fast reversal control for the motor is realized by the “software”stagger.The system has many advantages such as simple circuits,easy regulation and good performance.The system is worthy to be spreaded and used in the suitable situations.
