摘要:
本文首先分析了数控机床对进给伺服系统提出的各种要求,指出这些要求兼顾了控制电
机系统及驱动电机系统是极其苛刻的,因而,进给伺服系统成为活跃的研究领域.其次,评述
了区别于国外简易数控装置的某些简易进给伺服系统.本文还对三种比较流行的进给伺服系
统(步进电机系统,小惯量直流伺服电机系统,宽调速直流力矩电机系统)就数控机床的要求及
其本身的特点详细地进行了分析比较,并指出了其应用范围.本文还介绍了用计算机控制的
交流电机系统的基本概念.最后,对进一步研究数控机床进给伺服系统提出了建议.
Abstract:
First of all, in this article we'll discuss all kinds of demands on feeding servosystem
set by N. C. Machine-tool. These demands taking into consideration both the
system with control motor and driving motor rare indeed quite strict. There-fore the
feeding servo-system has become active in research sphere. Secondly, this article
makes comments on some simple feeding servo-systems, which are different from those
simple N.C. devices abroad. In this article, the three kinds of popular feeding servosystems
(system with stepping motor, system with low-inertia D. C. servo-motor, system
with wide bound speed-regulation D. C. torque motor) are analysed and compared
in details according to the above-mentioned demands and its characteristics.
The range of application of each kind is also pointed out. At the same time, a new
basic concept about the system with A.C. motor under the control, of a computer is
explained here. At the end of this article some suggestions have been put forward
to further study feeding servo-system for N.C. machine-tool.
