This article will introduce what a servo drive is, its working principle, application fields and future development trends.
What is a servo drive:
Servo drive is a control system that achieves precise control of the load by controlling the speed, position and torque of the motor. It usually consists of several key components, including servo motors, encoders, controllers and power amplifiers. Servo drive systems use feedback mechanisms to monitor and adjust output for precise control.

Working principle of servo drive:
The core of the servo drive system is the close cooperation between the controller and the motor. The controller obtains the encoder feedback information, calculates the output according to the preset control signal, and sends the result to the power amplifier. The power amplifier controls the driving voltage and current of the motor according to the control signal, thereby adjusting the movement of the motor. Through real-time feedback and adjustment, the servo drive system can enable the motor to accurately achieve the predetermined position, speed and torque at any point in time.
Application areas of servo drives:
Servo drive technology is widely used in various fields, including industrial machinery, robots, automated assembly lines, medical equipment, and aerospace. In industrial machinery, servo drives can achieve high-speed, high-precision position control, improving production efficiency and product quality. In the field of robotics, servo drives can precisely control the movement of joints and achieve complex actions and tasks. In medical equipment, servo drives can ensure the precise positioning and operation of surgical tools, improving the safety and success rate of surgery.
