Magnetic technology: China's next innovation hot spot

Abstract: at present, magnetic technology has been applied in a small range in aerospace, metallurgy, chemical industry, machinery and other fields. In the future, it will still have broad application prospects in emerging manufacturing fields such as generators, new energy vehicles, robots, CNC machine tools, clean energy and so on

no intermediate medium is required, and the brand popularity is further expanded. The rotating resistance is nearly zero; A spring system that can achieve shock absorption effect only by the combination of magnetic attraction and repulsion; Brake system that can be braked across the air without "hard friction" of brake pads...

at the first China Magnetic Technology Industry Development Summit Forum that ended recently, some companies exhibited and are developing magnetic technology products that are amazing. As a product with a wide range of uses, China is taking a joint approach of government, enterprises and research to develop more application scenarios for magnetic materials

China's rare earth reserves are also the world's most important component of the electronic universal testing machine. In the past 10 years, the rare earth permanent magnet industry has achieved an average annual growth rate of 30%. In contrast, the application research of magnetic materials in China is relatively backward, and the downstream industries have not grown at the same time, which restricts the greater value of rare earth resources

at the Summit Forum on the development of magnetic technology industry, the participants focused on the application of magnetic materials in the manufacturing industry, hoping to bring changes to "made in China"

Gan Yong, director of the national new material industry development expert advisory committee and academician of the Chinese Academy of engineering, said that the large-scale application of each new material will bring revolutionary changes to the manufacturing industry. "Magnetic materials realize the contactless conversion or transmission of energy through 'permanent magnetic field', which has the characteristics of connectionless, safe and efficient, and is expected to become the next innovation hotspot in China." Gan Yong said

at present, magnetic technology has been applied in a small range in the fields of aerospace, metallurgy, chemical industry and machinery proposed at the central city work conference. In the future, it will still be widely used in emerging manufacturing fields such as generators, new energy vehicles, robots, CNC machine tools, clean energy, etc. Gan Yong introduced that at present, the new robot only needs 24 ultra small and high-energy density rare earth permanent magnet servo motors to complete the function of facial expression. There are more than 100 rare earth new material components in high-end vehicles

the large-scale use of magnetic equipment will contribute to China's industry in energy conservation, emission reduction and green production. Take the transmission field as an example. At present, the power consumption of general equipment such as fans, pumps and compressors in China accounts for more than 40% of the industrial power consumption. According to Gan Yong's calculation, if magnetic drive is used, the motor and various loads can be driven to rotate without transmission shaft connection. The system operation efficiency of the equipment can be increased by 20%-40% on average, which can save the power generation equivalent to three Three Gorges power stations every year

at the same time, magnetic technology also has broad application space in the field of civil products. On the purchase platform, products like magnetic levitation globe and magnetic chip building blocks are not uncommon

the Chinese government has also realized the value of magnetic technology. In January this year, the Ministry of industry and information technology, the national development and Reform Commission, the Ministry of science and technology and the Ministry of Finance jointly issued the guidelines for the development of new materials industry, which clearly pointed out that the industrialization of rare earth magnetic materials and application devices should be accelerated, the rare earth permanent magnet energy-saving motors and supporting rare earth permanent magnet materials should be vigorously developed, and their application in key projects of energy conservation and environmental protection should be promoted

at present, magnetic drive equipment has been used in large industrial enterprises in China

how to make magnetic technology better integrate and change "made in China"? Yangwenhao, Secretary General of China Rare Earth Industry Association, advocates cross-border innovation, encourages exchange, discussion and cross cooperation between manufacturing talents and magnetic material technicians, and enables magnetic technology to solve more problems in the manufacturing industry

innovative exploration is under way. At this forum, CCID Research Institute of the Ministry of industry and information technology agreed that the load shall not be greater than 0.5% of the indicated value; Anshan Municipal Government of Liaoning Province has reached a strategic cooperation agreement. The two sides will organize domestic leading institutions in the field of magnetic technology to jointly establish Anshan magnetic application technology research institute, which is committed to the development of magnetic technology application and transformation

Anshan City is also preparing to set up a magnetic technology industry development fund, build a magnetic Valley Technology Town, actively promote the arrival of the "spring" of the magnetic industry, and provide a demonstration for the upgrading of the manufacturing industry in the old industrial base
