1、伺服系统（servo mechanism）是使物体的位置、方位、状态等输出被控量能够跟随输入目标（或给定值）的任意变化的自动控制系统。伺服主要靠脉冲来定位，基本上可以这样理解，伺服电机接收到1个脉冲，就会旋转1个脉冲对应的角度，从而实现位移，因为，伺服电机本身具备发出脉冲的功能，所以伺服电机每旋转一个角度，都会发出对应数量的脉冲，这样，和伺服电机接受的脉冲形成了呼应，或者叫闭环，如此一来，系统就会知道发了多少脉冲给伺服电机，同时又收了多少脉冲回来，这样，就能够很精确的控制电机的转动，从而实现精确的定位，可以达到0.001mm。直流伺服电机分为有刷和无刷电机。有刷电机成本低，结构简单，启动转矩大，调速范围宽，控制容易，需要维护，但维护不方便（换碳刷），产生电磁干扰，对环境有要求。因此它可以用于对成本敏感的普通工业和民用场合。

无刷电机体积小，重量轻，出力大，响应快，速度高，惯量小，转动平滑，力矩稳定。控制复杂，容易实现智能化，其电子换相方式灵活，可以方波换相或正弦波换相。电机免维护，效率很高，运行温度低，电磁辐射很小，长寿命，可用于各种环境。

2、交流伺服电机也是无刷电机，分为同步和异步电机，运动控制中一般都用同步电机，它的功率范围大，可以做到很大的功率。大惯量，最高转动速度低，且随着功率增大而快速降低。因而适合做低速平稳运行的应用。

1, servo system (servo mechanism) is an automatic control system that enables the object's position, orientation, state and other output controlled quantity to follow any change of the input target (or given value). The servo mainly depends on the pulse to position, basically can be understood in this way, the servo motor receives a pulse, it will rotate the corresponding Angle of a pulse, so as to achieve displacement, because the servo motor itself has the function of pulse, so each rotation Angle of the servo motor, will emit the corresponding number of pulses, so that the pulse accepted by the servo motor echoes. Or closed loop, so that the system will know how many pulses are sent to the servo motor, and how many pulses are received back, so that the rotation of the motor can be controlled very accurately, so as to achieve accurate positioning, which can reach 0.001mm. Dc servo motors are divided into brushed and brushless motors. Brush motor has low cost, simple structure, large starting torque, wide speed regulation range, easy control, and needs maintenance, but the maintenance is not convenient (change the carbon brush), electromagnetic interference, and the environment is required. Therefore, it can be used in cost-sensitive general industrial and civil applications.

Brushless motor small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, torque stability. The control is complex, easy to achieve intelligence, its electronic commutation mode is flexible, can be square wave commutation or sine wave commutation. The motor is maintenance-free, high efficiency, low operating temperature, small electromagnetic radiation, long life, and can be used in a variety of environments.

2, AC servo motor is also a brushless motor, divided into synchronous and asynchronous motors, motion control is generally used synchronous motor, its power range is large, can achieve a lot of power. Large inertia, low maximum rotational speed, and rapidly reduced with the increase of power. Therefore, it is suitable for low speed and smooth operation applications.
