技术说明：SAC-SW220EB ORMEC  伺服驱动器 控制模块

  直流伺服电机的工作原理与普通的直流电机工作原理基本相同。依靠电枢气流与气隙磁通的作用产生电磁转矩，使伺服电机转动。通常采用电枢控制方式，在保持励磁电压不变的条件下，通过改变电压来改变转速。电压越小转速越低，电压为零时，停止转动。因为电压为零时，电流也为零，所以电机不会产生电磁转矩，既不会出现自转现象。

直流伺服电机在数控系统中应用很多，但是直流伺服电机也有一定的缺点:它的电刷和换向器易磨损;电机最高转速的限制，应用环境的限制;结构复杂，制造困难，成本高。

二伺服驱动器

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。

Technical description: SAC-SW220EB ORMEC servo driver control module

The working principle of DC servo motor is basically the same as that of ordinary DC motor. Electromagnetic torque is generated by the action of armature air flow and air gap flux to make the servo motor rotate. The armature control method is usually used to change the speed by changing the voltage while keeping the excitation voltage unchanged. The smaller the voltage, the lower the speed. When the voltage is zero, stop rotating. Because when the voltage is zero, the current is also zero, so the motor will not produce electromagnetic torque, neither will there be rotation phenomenon.

Dc servo motor is widely used in numerical control system, but DC servo motor also has some disadvantages: its brush and commutator are easy to wear; The maximum speed limit of the motor, the application environment limit; The structure is complicated, the manufacture is difficult and the cost is high.

Two-servo driver

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 electric part, which includes two units, one is the power drive unit PM for the motor drive, and the other is the switching power supply unit to provide 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.
