伺服驱动系统的基本概念伺服系统是数控机床的重要组成部分，是连接数控装置（计算机）和机床之间的关键桥梁，伺服系统的性能在很大程度上决定了数控机床的性能，如数控机床的定位精度、跟踪精度、高移动速度等重要指标。建议我们先来学习一些基础概念，再学习各种进给伺服系统的控制方式。深刻理解掌握这部分知识，会对的学习后面的数控加工工艺有的帮助。

　　1、进给伺服系统（1）组成进给伺服系统是以机床移动部件（如工作台）的位置和速度作为控制量的自动控制系统，通常由伺服驱动装置、伺服电机、机械传动机构及执行部件组成。

　　（2） 作用接受数控装置发出的进给速度和位移指令信号，由伺服驱动装置作的转换和放大后，经伺服电机（直流、交流伺服电机、功率步进电机等）和机械传动机构，驱动机床的工作台等执行部件实现工作进给或快速运动。

　　（3） 基本技术要求　　① 精度高　　② 稳定性好　　③ 快速响应　　④ 调速范围宽（4）分类　　① 步进电机驱动系统　　② 直流伺服驱动系统：永磁直流伺服电动机　　③ 交流伺服驱动系统：永磁交流伺服电动机2、开环控制伺服系统开环进给伺服系统是数控机床中简单的伺服系统，执行元件一般为步进电机，其控制原理如图2所示。
