伺服系统的主要特点：(1)精确的检测装置：以组成速度和位置闭环控制(2)有多种反馈比较原理与方法:根据检测装置实现信息反馈的原理不同，伺服系统反馈比较的方法也不相同。目前常用的有脉冲比较、相位比较和幅值比较3种。(3)高性能的伺服电动机(简称伺服电机)：用于高效和复杂型面加工的数控机床，伺服系统将经常处于频繁的启动和制动过程中。要求电机的输出力矩与转动惯量的比值大，以产生足够大的加速或制动力矩。要求伺服电机在低速时有足够大的输出力矩且运转平稳，以便在与机械运动部分连接中尽量减少中间环节。(4)宽调速范围的速度调节系统，即速度伺服系统：从系统的控制结构看，数控机床的位置闭环系统可看作是位置调节为外环、速度调节为内环的双闭环自动控制系统，其内部的实际工作过程是把位置控制输入转换成相应的速度给定信号后，再通过调速系统驱动伺服电机，实现实际位移。数控机床的主运动要求调速性能也比较高，因此要求伺服系统为高性能的宽调速系统。
