A servo motor is a servo system used to control the rotation of a motor. In the past, servo systems were usually made up of several motors, drives and controllers. In industrial production, servo systems are widely used in automotive and mechanical engineering due to the high requirements for the accuracy, response speed, stability and reliability of the motor. Due to the problem of unstable rotational speed in mechanical drives, servo systems have high requirements for rotational speed. Generally speaking, when the speed exceeds a certain limit, it generates a strong torque on the motor, resulting in damage to the equipment; at the same time, over-torque problems occur, resulting in distortion of the torque waveform; and the instability of the speed also leads to accelerated wear of mechanical parts. The servo system must therefore be kept at a high level of accuracy in order to obtain good control, extend the service life of the machine and increase productivity.
Servo drives, also known as “servo controllers” and “servo amplifiers”, are used to control servo motors and are similar to inverters for ordinary AC motors. It is mainly used in high-precision positioning systems. Generally through the position, speed and torque of the three ways to control the servo motor, to achieve high precision drive system positioning, is the high-end products of transmission technology.

Servo drives are an important part of modern motion control and are widely used in industrial robots and CNC machining centres and other automation equipment. In particular, servo drives applied to control AC permanent magnet synchronous motors have become a research hotspot at home and abroad. The current AC servo drive design commonly uses a vector control-based current, speed and position 3 closed-loop control algorithm. The algorithm in the speed closed loop design is reasonable or not, for the entire servo control system, especially the speed control performance plays a key role.
