作为一种补贴马达间接变速装置，伺服电机是指在伺服体系中控制机器元件运转的发动机，将电压信号转化为转矩和转速以驱动控制工具。

As an indirect variable speed device for subsidizing motors, servo motors refer to engines that control the operation of machine components in a servo system, converting voltage signals into torque and speed to drive control tools.

伺服电机重要靠脉冲来定位，伺服电机吸收到1个脉冲，就会旋转1个脉冲对应的角度，从而实现位移。如许，和伺服电机担当的脉冲形成了呼应，体系便知道发了几多脉冲给伺服电机，同时又收了几多脉冲返来。因此，也就可以大概很准确的控制电机的转动，从而实现准确的定位。

Servo motors rely heavily on pulses for positioning. When a servo motor absorbs one pulse, it rotates the corresponding angle to achieve displacement. In this way, the pulse generated by the servo motor echoes, and the system knows how many pulses were sent to the servo motor and how many pulses were received back. Therefore, it is possible to accurately control the rotation of the motor and achieve precise positioning.

伺服电机实现了位置，速率和力矩的闭环控制，高速性能好，稳固并电机加减速的动态相合时间短，利用在火花机，机器手，准确的机器以及单片机控制等。

Servo motors achieve closed-loop control of position, speed, and torque, with good high-speed performance, stable and short dynamic matching time for motor acceleration and deceleration. They are used in spark machines, robotic arms, accurate machines, and microcontroller control.

在利用历程中必要细致：伺服电机油和水的掩护，伺服电机可以用在会受水或油滴侵袭的场合，但是它不是全防水或防油的。因此，伺服电机不该当安排或利用在水中或油侵的情况中。别的，在移动伺服电机的时，应把随电机设置装备部署的那根电缆牢固地牢固到一个静止的部门，而且应当用一个装在电缆支座里的附加电缆来延伸它，如许弯曲应力可以减到小。

In the process of utilization, it is necessary to be meticulous: the servo motor is protected by oil and water. The servo motor can be used in situations where it is susceptible to water or oil droplets, but it is not fully waterproof or oil proof. Therefore, servo motors should not be arranged or utilized in situations of water or oil invasion. In addition, when moving the servo motor, the cable deployed with the motor should be firmly secured to a stationary department, and an additional cable installed in the cable support should be used to extend it, so that bending stress can be minimized.
