Servo motor has been used as a performance of the unit, as the robot servo motor is the main elements affecting the robot operation function. Servo motor is also needs to break the robot industry in China one of the key board. 'Made in China 2025' planning all the arrangement of the robot servo motor policy: by 2020, function, accuracy, reliability, reach the level of similar foreign products. See: '2017 -Servo motor industry in China market in 2022 outlook and investment value evaluation report robot industry in China in the age of great change, demand rapid vertical integration, the robot as a kind of new and high technology, is an important support of industry to carry out the method. And to vigorously carry out the robot industry, for the servo motor is one of the robots center parts of natural become many enterprises compete to the layout of the hot category. Servo motor as the performance of the element in control system, was one of the three big central parts of the robot. Robot servo system by the servo motor, servo drive, most instruction organization, servo motor is the performance of the organization, is to rely on it to complete the movement, the servo driver is the power of the servo motor power supply, instruction organization is send speed pulses may be used for servo drive of the normal operation of cooperation. From the point of market planning, servo motor used in all 2014 industry planning of up to 6. 8 billion yuan, growth of 8. 3%; Meantime robot growth as high as 50%, rapid growth for servo system using ranked sixth in the industry, with 4. 6 200 million, accounting for market share. 2%. Robot needs on a global scale expands unceasingly, but our country is now the world's fastest-growing robot mall. From 2013 to 2016, our country have three years to become the world's top big industrial robot consumer market. IDC speculation by 2020, the robot store planning will reach $59. 4 billion in our country, our country market will account for more than 30% of total global robot mall, market space is huge. The robot's the huge demand for high speed increase will drive servo motor. Servo motor is the main elements affecting the robot operation function, also is our country the robotics industry needs to break one of the key board. 'Made in China 2025' planning all the arrangement of the robot servo motor policy: by 2020, function, accuracy, reliability, reach the level of similar foreign products. To break the problem of spare parts for imported depend on, our country's policy in promoting robot parts industry development gradually increase. Two months ago, the ministry and the National Development and Reform Commission jointly issued by the 'notice for promoting the healthy development of the industrial robot, for industrial low level repeated construction, key parts production problems, put forward to promote rational robot industry to carry out, strengthen key parts such as short break, cultivate leading enterprises and so on. Although the proportion of domestic servo motor in the market is lower, with foreign brands have larger on the technology and the function of distance, and the product quality and stability nor with foreign brands, but in recent years, domestic brand servo motor development is very quick, can form a complete set of servo motor of autonomous has, obtained the store must be recognized. Many domestic products with technical department near, have sprung up, ace, guangzhou numerical control equipment, more than 20 large planning such as the British witten servo motor brand. At present domestic servo motor stores are still at the stage of lower, the full use of function and function not placed in the important position. Servo manufacturers in the long run, the key success factors should be the product price, reliability, technical content, as well as market share and brand influence. Looking to the future, tolerance with servo prices falling, servo market rising, mid-range mall has a very large increase in space. In general, the robot has enormous influence on the operation reflected by the servo motor, thus precision servo motor is always key function indicators of advanced nature is the primary elements. Foreign advanced servo motor has been well used most of the use demand, the development of resources have been gathered in a single, high-end use and all the function improvement in fine copy cut stage. Thus domestic servo motor manufacturers a long way to go.
