1、伺服系统(伺服机构)是使物体的位置、方向、状态等输出被控量随输入目标(或给定值)的任何变化而变化的自动控制系统。伺服主要是靠脉冲来定位的，基本上可以这样理解，伺服电机接收到一个脉冲，它就会旋转相应角度的一个脉冲，从而实现位移，因为伺服电机本身具有脉冲的功能，所以伺服电机每旋转一个角度，就会发出相应数量的脉冲，从而使伺服电机接收到的脉冲产生回声。或者是闭环，这样系统就会知道发送了多少脉冲给伺服电机，又接收了多少脉冲回来，这样就可以非常精确地控制电机的旋转，从而实现精确定位，可以达到0.001mm。直流伺服电机分为有刷电机和无刷电机。有刷电机成本低，结构简单，起动转矩大，调速范围宽，控制方便，需要维护，但维护不方便(换碳刷)，有电磁干扰，对环境有要求。因此，它可以用于成本敏感的一般工业和民用应用。
无刷电机体积小、重量轻、输出大、响应快、转速高、惯性小、转动平稳、转矩稳定。控制复杂，易于实现智能化，其电子换相方式灵活，可进行方波换相或正弦波换相。该电机免维护，效率高，工作温度低，电磁辐射小，寿命长，可在多种环境下使用。
2、交流伺服电机也是一种无刷电机，分为同步电机和异步电机，运动控制一般采用同步电机，其功率范围大，可以实现很多功率。惯量大，最大转速低，并随着功率的增大而迅速减小。因此，它适用于低速和平稳运行的应用。
3、伺服电机内部转子为永磁体，驱动器控制U/V/W三相电场电磁场，转子在此磁场作用下旋转，同时电机自带编码器反馈信号给驱动器，驱动器根据反馈值与目标值进行比较，调整转子旋转角度。伺服电机的精度是由编码器的精度(行数)决定的。
交流伺服电机与无刷直流伺服电机在功能上的区别:交流伺服更好，因为它是正弦波控制，转矩脉动小。直流伺服是梯形波。但直流伺服更简单，更便宜。

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.
3, the rotor inside the servo motor is a permanent magnet, the driver control of U/V/W three-phase electric electromagnetic field, the rotor rotates under the action of this magnetic field, while the motor comes with the encoder feedback signal to the driver, the driver according to the feedback value and the target value to compare, adjust the rotor rotation Angle. The accuracy of the servo motor is determined by the accuracy of the encoder (number of lines).
The difference between AC servo motor and brushless DC servo motor in function: AC servo is better, because it is sine wave control and torque ripple is small. Dc servo is trapezoidal wave. But DC servo is simpler and cheaper.
