The speed-up development of industrial automation and the import substitution of servo systems will be accelerated.

the 2016 German robot and automation technology trade exhibition was held in Munich today. The exhibition covers many fields such as robot industrial production lines and commercial robots. It has become the largest robot industry and Automation Technology Expo in the world. The exhibition will also integrate the innovation of automation technology production and scientific research, share the most cutting-edge robot technology and scientific and technological achievements, and further promote the rapid development of industrial automation and robot accessories industry

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

at present, the joint drive of the robot cannot be separated from the servo system. The more joints, the higher the flexibility and accuracy of the robot, and the more servo motors to be used. The robot has high requirements for the servo system. It must meet the requirements of fast response, high starting torque, and the real arrival of the dynamic graphene period. It also needs a large photocathode inertia ratio and a wide speed regulation range. It must adapt to the conditions of small size, light weight, acceleration and deceleration operation of the robot, and need high reliability and stability. At present, AC servo system is widely used in industrial robots

the cost of servo system accounts for 24% of industrial robots, second only to the reducer. In recent years, with the improvement of industrial automation level and the popularization of robot technology, the servo system will be increased with the continuous improvement of robot sales. According to the statistics of China robot industry alliance, the sales volume of domestic industrial robots continued to grow last year, with a cumulative sales of 22257 units, an increase of 31.3% over the previous year. Among them, the sales of domestic multi joint robots accelerated, with the sales volume of more than 6000 sets, a year-on-year increase of 71.7%, accounting for 27.4% of the total sales volume of domestic industrial robots, an increase of 6.4 percentage points over the previous year. The sales volume of the factory's logistics robots exceeded 1700, with a year-on-year growth rate of 93.7%, an increase of 2.6 percentage points over the previous year. Coordinate robots are still the main type of domestic industrial robots. Last year, nearly 10600 robots were sold, accounting for 47.6% of the total robot sales

in terms of market share, at present, foreign servo enterprises have a market share of 75% in China. Among them, Japanese brands account for 50%; European and American brands account for 25%. However, domestic brands account for only about 20% of the market share. At present, the medium and low-end servo systems in China have been able to achieve large-scale mass production, but the high-end servo systems have not yet formed commercialization and mass production capacity. The domestic demand for precision servo motor control systems and the constant filtering of various service scenes in my mind mainly rely on imports. With the promotion of supporting policies to the robot industry and the continuous improvement of domestic servo technology, the pace of import substitution of servo systems in China will be accelerated
