Micromotor next stop: high-tech products
In the past two years, the annual output of the world's micro-motors has exceeded 16 billion units, and the annual output of various types of micro-motors made in China is about 11 billion units, accounting for 70% of the global market share, becoming the absolute production and sales leader in the world micro-motor industry.
Since the emergence of micro-motors in Switzerland, it developed in Japan, although micro-motors gradually shifted to developing countries as technology spread. But there is no doubt that countries such as Japan still hold advanced technologies in the micro-motor industry, and developing countries represented by China are undertaking industrial transfer in developed countries such as Japan. In China, the micro-motor industry has defined its future direction since 2013. Last year's Shenzhen Motor Magnetics Exhibition, micro-motors with large torque, small size, high control precision, long life and low cost have received extensive attention.
However, in terms of technological innovation, some people in the industry believe that: "Many domestic motor companies in terms of research and development of new motor products, compared with foreign companies, the advantages of R & D technology will be less obvious." Therefore, how is it not in the traditional domestic advantages of the project The breakthrough in technology research and development in the motor industry and the breaking of foreign technology blockades are the second biggest problems that micro-motor R&D engineers have to face.
Micro-motors are a technology-intensive industry, and the development of new products for micro-motors has always been a matter of great concern in the industry. When it comes to micro-motor improvements that will lose some of the old performance, here is an example: For example, if you want to improve the cogging torque of a micro-motor, the rotor should have a chute, or the magnet should be eccentric. In this case, the torque of the motor is reduced compared to the straight groove or the magnetic watt is not eccentric, and the difficulty of the production process is also increased, which is a relatively large test for research and development.
The role of micro-motors is especially the No. 3, which was successfully launched last year. All of the micro-motors used are from domestic independent research and development, which to some extent represents the future research and development direction of micro-motors. It is foreseeable that with the development of aviation technology and weaponry automation, the micro-motor industry will be led by the market to a high-tech direction.
