Domestic servo motor import substitution acceleration! Break the monopoly between the United States and Japan
The high-end market for domestic robot servo motors has been occupied by famous companies such as Panasonic, Mitsubishi, Yaskawa, and Bosch in Japan and Europe and the United States. This has not only led to the long-term reliance on imports of robotics companies in China, but also affected the development of the industry. However, with the gradual acceleration of import substitution of domestic servo products, this situation has begun to change. Break the monopoly of the United States and Japan and realize import substitution Recently, a batch of servo motors in the production workshop of Lianyi Motor, Hengdian Town, Dongyang City, are undergoing final online commissioning, and then they will be exported to a Japanese robot company. Why is the famous Japanese robotics company "falling in love" with a domestic servo motor? According to reports, this self-developed servo motor lasted for four years not only passed 2 million tests, but also had the advantages of small size, light weight, and strong current overload capability. Its test life has reached an astonishing 20,000 hours, which is several times that of similar companies. The emergence of this domestic servo motor not only broke the monopoly of the American and Japanese companies in the industry, but also accelerated the entry of the robot manufacturing industry in China into the "servo era." It means that domestic manufacturers have not only overcome some of the challenges of industrial robot servo motors, but have also steadily advanced the localization of robot components. While reducing the cost of domestic robots, the proportion of domestically-manufactured robots in new installed capacity has been increased. Obviously, with the continuous increase in the output of industrial robots in China, industrial robot manufacturing continues to break through three critical core component technologies, such as speed reducers, servo controls, and servo motors, which have been criticized by the industry. This has accelerated China's manufacturing industry to high-end industrial value chains. A typical representative. In fact, whether the blockade of the servo motor or the steady development of the speed reducer or the controller entering the high-end market shows that China’s long-term control of key components of industrial robots by foreign companies is slowly changing. . Breaking through the technical blockade is significant As one of the three core components in the robot control system, the servo motor is not only the main factor that affects the work performance of the robot, but also one of the key shortcomings that our country's robot industry needs to break through. Unfortunately, despite its lower cost share than the reducer, this area is still very weak in terms of localization. In this regard, an insider of a well-known domestic robot system development company has also stated that due to the foreign country's high-power servo motors, Chinese enterprises have been completely blocked, and sales to domestic robot manufacturers are not open, which has seriously affected the development of China’s robot industry. . To this end, China has clearly deployed the robot servo motor in the “Made in China 2025†plan: By 2020, the performance, precision, and reliability have reached the level of similar foreign products. Thanks to changes in the market environment, domestic equipment manufacturers have begun to take the initiative to upgrade because of the large demand for high-performance, relatively affordable servo products in recent years. At present, the self-supporting capabilities of domestic brands of servo motors have begun to take shape and have gained certain market recognition. Domestic inverters that started relatively earlier have already achieved good results in the OEM market, and many domestic manufacturers such as Incheon Technologies, Eston, Guangzhou CNC, Infinova and other more than 20 large-scale servo motors have been technically and Japanese. The product is close. Faced with challenges still need to make up for the short board It is worth noting that despite the gradual localization of core components such as servo motors, the cost of industrial robots has been further reduced, and the innovation results have gradually emerged, but there is still a big gap between technology and performance and foreign brands. And stability is not the same thing. For example, for the reliability of signal connectors of servo motors, the current domestic servo motors still need to continue to improve. In order to make it easier to install, debug, and replace, plug-in miniaturization and high density are also the trend. In addition, high-precision encoders are also one of the core technologies of servo motors. In particular, multi-turn absolute encoders used in industrial robots are still heavily dependent on imports. In fact, high-precision encoders have become one of the important bottlenecks restricting the development of high-end servo systems in China. The lack of basic research on domestic servo systems is a difficult problem to be solved. Such as absolute encoder technology, industrial manufacturing technology of high-end motors, breakthroughs in production technology, practical verification of performance indicators, and development of assessment standards. All these need the core parts and components companies in the domestic robotics industry to gradually improve. Therefore, in the domestic R&D of robotics technology, China still needs to increase investment in key technologies and R&D to increase the self-sufficiency rate of components. At the same time, nurture independent intellectual property brand and enlarge the domestic industrial robot industry.
