As the core component of industrial robot, servo motor is the "heart" of industrial robot power system and motion system ". The joint drive of the robot is inseparable from the servo system. The more joints, the higher the flexibility and accuracy of the robot, and the more servo motors are used. The servo system is very demanding. It must meet the requirements of fast response, high starting torque, large torque-to-inertia ratio, and large speed range to adapt to the robot's small size, light weight, acceleration and deceleration operation conditions, and high reliability. and stability. Currently, most industrial robots use AC servo motor systems.
AC servo motor has good speed regulation performance, stable operation, almost no impact, low calorific value, fast speed regulation and high precision. In the rated working area, it can achieve constant torque, low inertia, low noise, brushless wear and maintenance-free (suitable for dust-free and corrosion-free environments).
Therefore, AC servo motors have also been widely used in industrial robots. At present, foreign servo motor brands have better advantages. Among them, the servo series represented by the Japanese series has stable quality and high quality, and has been occupying most of the servo market. Of course, we also believe that the domestic servo system will get better and better in the future. Whether it is a domestic brand or a Japanese brand servo, we are working hard for the rapid development of China's industrial automation. Now we also predict the future development direction of servo motors. I hope that this analysis will give us a clearer picture of the way forward.
1.Intelligent: The servo drive will be continuously updated to make it more intelligent.
2.Digitization: It is an inevitable trend of digital control technology to replace analog control circuits in servo systems.
3.Grid: build network and bus dedicated server systems. Bus is a kind of digital communication technology applied in production field. It realizes two-way, serial and multi-node communication between field devices and control devices and between field devices and control devices. The construction of bus servo system is an inevitable requirement of industrial Internet of things.
4.High efficiency: Servo motors will inevitably adopt high-precision encoders to improve their operating accuracy. It will also improve the product performance of the drive, continuous optimization and update
5.Simplification: In the future, we will try to form simple modular programming operations according to customer requirements to make users more convenient and faster to use.
What is shared above is the future application of servo motors in industrial robots and the role of servo motors.
