Domestic servo motor manufacturers have a long way to go, filling parts into key shortcomings
As an execution unit in a robot, a servo motor is a major factor affecting the performance of the robot. Servo motor is also one of the key shortcomings that China's robot industry needs to break through. The "Made in China 2025" plan has deployed the goal of robotic servo motors: by 2020, the performance, accuracy and reliability have reached the level of similar foreign products.
Completing the key short-board parts of the domestic servo motor industry has a long way to go
China's robot industry is in a period of great change, and it needs rapid innovation and integration. As a high-tech, robots are an important means of supporting industrial development. To develop the robot industry, servo motors, one of the core components of robots, have become a hot area for many companies to compete.
As the actuator in the control system, the servo motor is one of the three core components of the robot. The robot servo system consists of three parts: servo motor, servo drive and command mechanism. The servo motor is the actuator, which relies on it to realize the motion. The servo drive is the power supply of the servo motor. The command mechanism is used to pulse or give speed. Works with the servo drive.
In terms of market size, in 2014, servo motors were 6.8 billion yuan in all application industries, with a growth rate of 8.3%; among them, robots grew at a rate of 50%, rapidly growing into the sixth-ranked industry in servo system applications, with 420 million Performance, accounting for 6.2% of the market.
The demand for robots is expanding globally, and China is now the fastest growing robot market in the world. From 2013 to 2016, China has become the world's largest consumer market for industrial robots for three consecutive years. IDC predicts that by 2020, the Chinese robot market will reach 59.4 billion US dollars, and the Chinese market will account for more than 30% of the global robot market. The market space is huge. The rapid growth of robots will drive the huge demand for servo motors.
Servo motor is the main factor affecting the performance of robots, and it is also one of the key shortcomings that China's robot industry needs to break through. The "Made in China 2025" plan has deployed the goal of robotic servo motors: by 2020, the performance, accuracy and reliability have reached the level of similar foreign products.
In order to break through the dependence of parts on foreign imports, China's policy is gradually increasing the development of the robot parts industry. Two months ago, the Ministry of Industry and Information Technology and the National Development and Reform Commission jointly issued the "Notice on Promoting the Healthy Development of the Robot Industry". In response to the low-level duplication of construction and the manufacture of light key components, the paper proposed to promote the rational development of the robot industry and strengthen key short-term breakthroughs in parts and components. , vigorously cultivate leading enterprises and so on.
Although the proportion of domestic servo motors in the market is relatively low, there is a big gap between technology and performance and foreign brands, and product quality and stability cannot be the same as foreign brands, but in recent years, domestic brands of servo motors The development is also very rapid, and the self-supporting capability of the servo motor has taken shape and has gained certain market recognition. Many domestically produced products are technically close to Japanese products, and more than 20 large-scale servo motor brands such as Eston, Guangzhou CNC equipment, and Yingweiteng have emerged.
At present, the domestic servo motor market is still at a lower stage, and the full utilization of performance and functions is not in an important position. In the long run, the key success factors for servo vendors should be product price/performance, reliability, technology content, and market share and brand influence. Looking into the future, with the continuous decline in servo prices and the increasing acceptance of the servo market, the low-end market has a very large room for growth.
In general, the performance of the robot is greatly affected by the servo motor, so the key performance indicators of the precision servo motor are always the primary factor for the comparison of the advanced. Foreign advanced servo motors have been well adapted to the needs of most applications, and their R&D resources have been concentrated on individual high-end applications and overall performance enhancements. Therefore, domestic servo motor manufacturers have a long way to go.
