With the continuous development of industrial automation, robots have been widely used, and servo motors, one of the core components of robots, have also made great progress. Nowadays, the scale development of servo motors in China has been formed. However, due to the impact of technology and foreign companies, it is necessary to cooperate with government and enterprises in the future to accelerate the emergence of domestic substitution and brand rise.


In recent years, with the continuous upgrading of modern industrial technology, the level of automation has become an important indicator to measure the development of the national manufacturing industry. As the core equipment and hardware foundation for promoting the development of automation, industrial robots have been widely concerned and valued by various countries.


Under such a background, China is also actively deploying the development of the industrial robot industry. However, due to the lack of core technology, the core components of industrial robots in China can only rely on imports for a long time. Among them, the dependence of servo motors on imports is particularly serious, which greatly restricts the development of China's robot industry.


China's servo motor market development status


It is understood that the servo motor is an engine that controls the operation of the mechanical components in the servo system, and is an auxiliary motor indirect shifting device. In industrial robots, AC servo motors with high starting torque, high torque, and low inertia have great room for performance.


At present, under the demand of national automation development, the machine substitution trend has become more and more fierce. Industrial robots have been widely used. As a servo motor that assists the robot in achieving precise positioning and motion, it has also ushered in rapid development.


In 2014, the sales volume of servo motors in China's market has exceeded half of the global sales. At the same time, according to the "2015-2019 Global Industrial Robot Servo Motor Industry Report", the market size of China's servo motor reached 12.2 billion yuan in 2015. It has gradually become one of the major demand markets in the world. It is estimated that by 2019, the demand for servo motors in China will exceed 700,000 units.


However, it is a pity that the current domestic high-end market is mainly occupied by enterprises in Japan and Europe and the United States. Among them, Japanese brands account for more than 50% of the market share, Panasonic, Mitsubishi Electric, Yaskawa, Sanyo, Fuji and other brands monopolize China's small and medium-sized OEM market, and in the large servo market, Siemens, Bosch Rex and other European brands Also have the traditional advantages.


At the same time, in the low-end market where Chinese enterprises are living, they are also suffering from the invasion of Taiwanese brands. They are close to the performance of Japanese brands and the low prices of domestic brands, which have a strong impact on Chinese enterprises.


In the future, we must fully accelerate the domestic substitution.


In general, the development of the servo system is not too late in China. It has entered the third stage of development since 1955. The robot servo motor is the main product of this stage, and the ultimate goal is to complete the import of the brand. Complete replacement, to achieve the rise and development of domestic brands.


Nowadays, in the case that the high-end market is monopolized and the low-end market is facing fierce competition, the situation is not optimistic, but on the contrary, it can be said that the space for domestic substitution is very huge. In order to realize the potential of China's servo motor development, it is necessary for domestic enterprises to speed up technological breakthroughs, the national government to increase support, the industrial industry to accelerate the formation of standards, and the three parties to jointly create a development path to achieve the brand's breakthrough and rise.


It is gratifying that in recent years, domestic enterprises have made great breakthroughs in the related technologies of servo motors. Recently, Gree started from three aspects of power density, cogging torque and current loop design, and independently developed high-performance servo motors and drivers for industrial robots. However, companies such as Incheon Technology and Invitrogen also developed servo technology. From the field of inverters to the servo market, the international competitiveness of local companies has been strengthened.


At the same time, the government also issued the "Made in China 2025" and other related documents, the overall deployment of the robot servo motor development, the requirements of the domestic servo motor performance, accuracy, reliability to 2020, to the level of similar foreign products And accelerate the domestic substitution of imports to achieve self-reliance of servo motors in China.


Under the circumstance of the development of technology, the government policy guidance continues to strengthen, and the cohesiveness of local enterprises is increasing. Under the blessing of domestic enterprises, the domestic market share of the domestic brands has risen to about 20%, and the march for the mid-to-high-end market is also constantly trying. The industrial chain of the domestic servo industry is also increasingly optimized... I believe that in the near future, we will be able to achieve a complete replacement and strong rise of domestic brands.
