In the era of continuous innovation in automation technology, the servo system, as one of the core technologies of industrial automation, is like the "executor" of precision machinery. With its high-precision and high-response characteristics, it promotes various industries to move towards intelligence and high efficiency.

The servo system is a feedback control system that can accurately follow or reproduce a certain process. It mainly consists of four parts: servo motor, servo driver, encoder, and controller. The servo motor is the execution element, which outputs torque and speed according to the signal of the driver to achieve mechanical movement. The servo driver is equivalent to the "brain center" of the servo motor. It receives the command signal from the controller, modulates, converts, and amplifies it, and then drives the servo motor to operate. The encoder, as the "eyes" of the system, real-time detects information such as the position and speed of the motor and feeds the data back to the driver and the controller to form a closed-loop control. The controller is responsible for sending control commands and coordinating the work of each part.

Its working principle is based on the closed-loop control mechanism. When the controller sends a motion command, the servo driver drives the servo motor to operate, and the motor drives the load to move. During this process, the encoder monitors the actual operating status of the motor in real-time and feeds back information such as position and speed to the driver and the controller. The controller compares the feedback information with the command signal. If there is a deviation, it will adjust the output signal and correct the motor through the driver until the actual operating status is consistent with the command requirements, thus achieving precise control.

The servo system has many significant advantages. High precision is its outstanding feature. Through closed-loop control, the position error can be controlled within a very small range, meeting the application scenarios with extremely high precision requirements such as precision machining and semiconductor manufacturing. High responsiveness enables it to quickly respond to control commands and reach the target speed and position in a short time, greatly improving production efficiency. Good stability ensures that the system can operate continuously and reliably under complex working conditions, reducing the occurrence of failures. In addition, the servo system supports flexible speed regulation and torque control and can be accurately adjusted according to different working requirements.

Based on these excellent performances, the application of the servo system is very extensive. In the manufacturing industry, it is widely used in CNC machine tools to achieve precise positioning of the tool and high-speed cutting, ensuring machining accuracy and surface quality. In the field of robotics, the servo system provides power and precise control for the joints of the robot, enabling it to complete complex movements. In the automated production line, the servo system drives equipment such as conveyor belts and robotic arms to achieve precise handling and assembly of materials. In high-end fields such as aerospace and medical devices, the servo system also plays a key role, such as aircraft rudder surface control and precise positioning of medical imaging equipment.
