DC motor is used in robot, aviation and other fields
Micromotor, abbreviated as small motor, is often used in the control system. It is an electromechanical component to realize the function of electromechanical signal solution, amplification, execution or electromechanical energy conversion, just like human joint muscle and nerve endings. Driven by the demand of downstream application industry, China's micro motor manufacturing industry develops rapidly. According to incomplete statistics, in 2014, there were more than 3600 Enterprises above the scale of China's micro motor industry, with annual sales of more than 140 billion yuan and a year-on-year growth rate of more than 10%. Fan Youshan, general manager of China Electronics Technology Group Corporation, told the Economic Daily that the average household ownership of micro motors in developed countries is between 80 and 130, while the average household ownership in big cities in China is only between 30 and 60. If the average usage of each household increases by 1 set per year, the demand of micro motor in China will increase by 300 million to 400 million sets per year, which has great market development potential.
Shi Jinhao, director of the micro motor and component branch of China Electronics Industry Association and director of 21 Institute of CETC, said that micro motors are widely used in household appliances, automobiles, robots, aerospace and automation fields. Industry 4.0 is the networked and information-based system control of intelligent manufacturing. Micro motors and components will play an irreplaceable role.
"China's manufacturing industry is facing a huge challenge of changing to high-end, undertaking international advanced manufacturing and participating in international division of labor." Gong Xiaofeng told the Economic Daily that with the upgrading of people's consumption demand, the traditional manufacturing industry has the requirements of intelligent manufacturing after China has become a big country of traditional manufacturing industry, and the micro motor, as the "actuator", will surely have a place in application due to the perfect integration of electronic technology.
Fan Youshan said that at present, the permanent magnet AC servo motor products of industrial robots and core components are still dominated by foreign companies. At present, there are thousands of kinds of micro motors independently developed by CETC, and the products are widely used in aerospace ships, industry, transportation, medical and other fields. The intelligent equipment state-owned capital project led by CETC plays an important role in helping China's small motor industry to improve its independent innovation ability and realize localization of key executive parts of intelligent equipment.
"Modern micromotor is developing towards miniaturization, high precision and intelligence, and its product grade is higher and higher. Its market is large, its application is wide, its development is fast, and its variety is attracting worldwide attention. It has become an advantageous industry suitable for the development of developing countries." Shi said that how to adjust the industrial structure, accelerate development, expand the international market share, and make China realize the transformation from the world's largest producer of small motors to a powerful country as soon as possible is a problem that China's micro motor industry needs to think about together.
