伺服电机(servo motor )是指在伺服系统中控制机械元件运转的发动机，是一种补助马达间接变速装置。

伺服电机可以控制速度，位置精度非常准确，可以将电压信号转化为转矩和转速以驱动控制对象。伺服电机转子转速受输入信号控制，并能快速反  应,在自动控制系统中，用作执行元件，且瞑有机电时间常数小、线性度等特性,可把所收到的电信号转换成电动机轴上的角位移或角速度输出。

分为直流和交流伺服电动机两大类,其主要特点是，当信号电压为零时无自转现象，转速随着转矩的增加而匀速下降。

servo motor (servo motor) refers to the engine that controls the operation of mechanical components in the servo system, which is a supplementary motor indirect transmission device.

The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. Servo motor rotor speed is controlled by the input signal, and can react quickly, in the automatic control system, used as an executive component, and close to the electromechanical time constant is small, linearity and other characteristics, the received electrical signal can be converted into the angular displacement or angular speed output on the motor shaft.

Divided into DC and AC servomotor two categories, its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases with the increase of torque.
