摘　　要：在电压负反馈和电流正反调速控制系统中增设了自动限制电枢电流的电路,并能实现在正常运行时限制电枢电流电路与负反馈调速控制系统自动分离,当电流增大到一定程度时又能自动投入.既克服了由于电流负反馈使系统的静特性变软的不足,又能满足一般调速系统的要求.A automatic limit armature current circuit was added to the control system of the negative voltage feedback and the electric current forward and reverse speed regulation,which could realize the automatic separation within the limiting armature current circuit and the negative feedback speed regulation control system during normal operation,and could automatically be combined when the current increasing to a certain extent.The new system can be used not only to overcome the static properties softened deficiency due to the current negative feedback,it also better meet the requirements of the general speed control system.
