The servo motor is used to drive the joints of the robot. It is required to have the maximum power-to-mass ratio and torque-inertia ratio, high starting torque, low inertia, and a large and smooth speed adjustment scale. The growth of the robot industry requires breakthroughs in servo motors, integrated control, and other fields in order to make progress.
Now, it has a huge impact on the industrial robot industry. The general structure of the industrial robot electric servo system is three closed-loop controls, namely the current loop, the speed loop and the position loop. In general, for the communication servo driver, it can realize the position control, speed control, torque control and other functions by manually setting its internal function parameters.
The industrial automation process continues to drive, and the demand for automation software and hardware equipment remains high. The domestic industrial robot market has been steadily increasing. It is estimated that China will become the world's largest demand market in 2025.
At present, AC and DC servo motors with high starting torque, large torque, and low inertia are widely used in industrial robots. Other motors, such as communication servo motors and stepper motors, will also be used in industrial machines according to different usage needs.
