1.概念

伺服驱动器又称为伺服放大器或放大器，是将从控制器输入的脉冲信号或模拟量信号经内部计算放大后输出给电机的装置。

⒉结构及原理

伺服驱动器主要有伺服股控制单元、功率驱动单元、通讯接口单元组成。其中伺服控制单元包括位置控制器、速度控制器、转矩和电流控制器等。

伺股驱动器大体可以划分为功能比较独立的功率板和控制板两个模块。功率板是强电部分，其中包括两个单元，

一是功率驱动单元PM用于电机的驱动，

二是开关电源单元为整个系统提供数字和模拟电源。控制板是弱电部分，是电机的控制核心也是伺服驱动器技术核心控制算法的运行载体。

控制板通过相应的算法输出PWM/PFM信号，作为驱动电路的驱动信号，来改变逆变器的输出功率，以达到控制交流伺服电机的目的。

1. Concept

The servo driver, also known as the servo amplifier or amplifier, is a device that outputs the pulse signal or analog signal input from the controller to the motor after internal calculation and amplification.

⒉ Structure and principle

The servo driver is mainly composed of servo control unit, power drive unit and communication interface unit. The servo control unit includes position controller, speed controller, torque controller and current controller.

The actuator can be divided into two modules, the power board and the control board, with relatively independent functions. The power board is the strong current part, which consists of two units,

First, the power drive unit PM is used to drive the motor.

Second, the switching power supply unit provides digital and analog power for the entire system. The control board is the weak current part, the control core of the motor and the operating carrier of the core control algorithm of servo drive technology.

The control board outputs PWM/PFM signal through the corresponding algorithm, which is used as the drive signal of the drive circuit to change the output power of the inverter, so as to achieve the purpose of controlling the AC servo motor.
