The control system and automation products of industrial robots mainly involve servo motors, reducers, controllers and sensors. As an important part of industrial automation, the servo system is mainly used to accurately follow or reproduce the feedback control system of a certain process. The servo system is an automatic control system that enables the output of the controlled quantity such as the position, orientation, and state of the object, and can follow the input target to change arbitrarily. The servo system is divided into hydraulic servo system, electrical servo system and pneumatic servo system according to the different actuators. Servo systems are widely used in the fields of machine tools, textiles, printing and packaging machinery. At the same time, with the rapid expansion of industries such as industrial robots and electronic manufacturing equipment in recent years, the application scale of servo systems in emerging industries will also accelerate.

At present, the joint drive of the robot is inseparable from the servo system. The more joints, the higher the flexibility and precision of the robot, and the more servo motors to use. The robot has high requirements for the servo system, which must meet the requirements of fast response, high starting torque, large dynamic moment of inertia ratio, and wide speed range. It must adapt to the shape of the robot to achieve small size, light weight, and acceleration and deceleration. And requires high reliability and stability. At present, industrial robots use more AC servo systems.

The cost of servo system accounts for as high as 24% in industrial robots, second only to the cost reduction of industrial robots.

Among them, the sales of domestic multi-joint robots accelerated, with sales exceeding 6,000 units, a year-on-year increase of 71.7%, accounting for 27.4% of the total sales of domestic industrial robots, an increase of 6.4 percentage points over the previous year. The sales of factory logistics robots exceeded 1,700 units, with a year-on-year growth rate of 93.7%, an increase of 2.6 percentage points from the previous year. Coordinate robots are still the main model of domestic industrial robots, with sales of nearly 10,600 units last year, accounting for 47.6% of total robot sales.

From the perspective of market share, the current market share of foreign servo companies in my country is as high as 75%. Among them, Japanese brands accounted for 50%; European and American brands accounted for 25%. The domestic brands only occupy about 20% of the market share. At present, my country's low-end servo systems have been able to achieve large-scale mass production, but high-end servo systems have not yet formed commercialization and mass production capabilities. The domestic demand for precision servo motor control systems mainly relies on imports. With the promotion of supporting policies for the robot industry and the continuous improvement of domestic servo technology, the pace of import substitution of servo systems in my country will accelerate.
