伺服可作为交流或直流电动机。早期一般伺服直流电动机，因为只有类型的控制大电流是通过序列多年。随着晶体管成为能够控制大电流和开关的大电流在更高的频率，交流伺服电机成为更经常地使用。早期伺服是专为伺服放大器。今天，一类是电机设计的应用，筹措，可能使用伺服放大器或变频控制器，这意味着电动机可用于伺服系统在一个应用程序，并使用变频驱动器在另一应用程序。有些公司还要求任何闭环系统，不使用步进电机伺服系统，所以它是可能的一个简单的交流感应电机是连接到一个速度控制器，被称为伺服电机。

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。伺服电机可使控制速度，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，且具有机电时间常数小、线性度高、始动电压等特性，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。

准确讲，伺服电机是一种数字化控制的电机，能够将电能转换为机械能，用于定位控制。其位移是通过脉冲信号数量控制的，转速是通过脉冲频率控制的。伺服电机属于闭环控制的电机，必须采集电机旋转轴的编码器信号，才能够实现控制。与此相反的，是步进电机，这种电机能够实现开环控制。通常伺服电机，不是说“容量”，而是说功率。其功率能够做的很小，也可以做得非常大，甚至几十或者几百千瓦。

Servo can be used as AC or DC motor. Early general servo DC motor, because only the type of control large current is passed through the sequence for many years. As transistors became able to control high currents and switch high currents at higher frequencies, AC servo motors became more often used. Early servo amplifiers were designed for servo. Today, one class of motor design applications, financed, may use servo amplifiers or variable frequency controllers, meaning that the motor can be used in a servo system in one application and a variable frequency driver in another application. Some companies also require any closed-loop system that does not use a stepper motor servo system, so it is possible for a simple AC induction motor to be connected to a speed controller, known as a servo motor.

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 has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc., can convert the received electrical signal 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.

To be precise, a servo motor is a digitally controlled motor that can convert electrical energy into mechanical energy for positioning control. The displacement is controlled by the number of pulse signals, and the speed is controlled by the pulse frequency. The servo motor belongs to the closed-loop control motor, and the encoder signal of the motor rotation shaft must be collected to realize the control. In contrast, it is the stepper motor, which can achieve open-loop control. Usually the servo motor, not to say "capacity", but to say power. Its power can be done very small, can also be done very large, even tens or hundreds of kilowatts.
