龙门刨直流可逆控制系统的研制与应用

Study and Application of DC Current Returnable Control System on Portal Planer

直流可逆系统用来控制直流电动机的转速和转向 ,从而实现执行机构 (如龙门刨 )的可逆运行。而可逆系统中正、反两组整流桥的工作切换方式有几种 ,可靠性较高的是无环流切换 ,笔者设计了逻辑无环流可逆系统。本文对该系统的逻辑无环流切换电路的组成和工作原理作了介绍 。

The rotating speed and rotating direction of DC.motor is controled by the DC.returnable system which carry out the returnable performing on actuator(for example:Portal Planer).In returnable system there are kinds of switch styles on positive and negative two group rectification bridger,the higher reliability is no cycle current switching,writer designed the logical no cycle current returnable system.This paper intrueluees the compsing and working principle of logical no cycle current switching circuit system,the schemes of funlction circuit are given.
