串励直流电动机使用无触点可控硅斩波调速的研究

A STUDY ON SPEED CONTROL OF SERIES D. C.MOTOR WITH CONTACTLESS SCR CHOPPER

本文提出了串励直流电动机使用新型无触点斩波调速的新方法。通过两组二段式斩波电路,主电路完全无触点化成为可能,而且扩大了调速使用范围,也证明了可应用于双机车牵引同步自动化控制。

This paper presents a new method of speed control for series D. C. moter with contactless SCR chopper, It is possible to make the main circuit be totally contactless and to extend speed control range through two sets of double-step chopping circuits. It is also proved that the principle can be applied to double locomotive traction for synchronous automatic control.
