The Working Principle and Uses of a Servo Drive System

A servo drive system works as a supplier of power to electric servomechanisms. It is a kind of electronic amplifier that monitors a servomechanism’s feedback signal and continuously works to adjust it if deviates from the required limit.

Uses of a Servo Drive System

The Industry Applications of a Servo Drive System

Servo drives have various industry uses including robotics, factory automation, and CNC machining among others. They feature motor feedback, which gives them an edge over the AC and DC motors. The motor feedback is efficient in detecting random motion and making sure that the commanded motion is accurate.

How Servo Drives Work

A servo drive system works for keeping the motion of a network proportional to the command signal. It amplifies the signal after receiving it from a control system and then channels electric current to a servo motor for producing the required motion.

The control system commands a velocity, torque, or position by sending signals. The servo drive receives the actual status of the servo motor through a sensor attached to the motor. The drive then ensures the correct flow of the desired motion by adjusting the voltage frequency or pulse width.

The primary function of a servo drive is to create a balance between the rotating velocity of the servo motor and the commanded velocity signal. The process of adjusting the parameters to achieve the desired result is called performance tuning.
