China News Service, Zhuzhou, December 10th (Liu Man Wen Yizhou) 2021 China International Rail Transit and Equipment Manufacturing Industry Expo is being held in Zhuzhou, Hunan, at the "One Magnet Starts to Move My Heart" Permanent Magnet Power Technology and Market Application Forum, Chinese Academy of Engineering Academicians Liu Youmei, Wang Yaonan, Ding Rongjun, Huang Xiaowei and other experts discussed the way of permanent magnet power technology and discussed the development strategy of industrial application.
Permanent magnet power and transmission technology is a high and new technology that uses permanent magnet materials to generate magnetic force and realize non-contact transmission. It is known as the third revolution of power transmission technology and is widely used in rail transit, new energy vehicles, aerospace, Wind power and other fields are the core components of high-end manufacturing and intelligent manufacturing.
Zhuzhou started the development of permanent magnet power technology and products in 2003. In particular, CRRC Zhuzhou Electric and CRRC Zhuzhou Institute have trained a large number of industrial technical workers in permanent magnet motors and other fields after years of technical reserves. The city has more than 400 core technical talents engaged in permanent magnet application research, and an industrial chain integrating R&D, design, manufacturing, and after-sales service has been initially formed, and the output value has exceeded 10 billion yuan.
This forum focuses on permanent magnet power technology and market applications, and is oriented to serve the national manufacturing power strategy, the national energy-saving and consumption reduction strategy, and the major national and regional economic development strategies. It aims to jointly explore the new technological direction and market of the permanent magnet power industry Opportunities to promote the coordinated development of the entire industrial chain of permanent magnet power, and continuously improve the core competitiveness of China’s permanent magnet drive technology industry.
"Permanent magnet power system is an important technical way to achieve energy saving, emission reduction, and environmental protection. It is an important development direction of next-generation power system and has become the focus of global innovation." Research and analysis found that compared with traditional asynchronous motors, the average total energy saving rate of permanent magnet motors exceeds 30%.
In the industrial field, the power consumption of motors accounts for about 75% of the industrial power consumption. The permanent magnet power system is energy-saving and environmentally friendly, and it is the preferred energy-saving and efficiency-increasing method in the future.
Ding Rongjun also pointed out that vigorously promoting the high-quality development of the permanent magnet power industry can help achieve the goal of carbon peak and carbon neutrality.
He suggested focusing on the entire industrial chain of permanent magnet power, focusing on key common technologies, promoting collaborative innovation across the entire industrial chain, focusing on building a supporting system for the permanent magnet power industry, and cultivating permanent magnet power with a sound industrial chain, complete professional collaboration mechanisms, and strong competitiveness. Industrial clusters.
Liu Youmei believes that permanent magnet motors are currently widely used in wind power generation, electric vehicles, ship propulsion, metallurgical steel rolling, central air conditioning and other fields. They also have successful operation performance in the field of rail transit and have gradually entered the engineering promotion stage.
"With the development of digital technology, intelligent permanent magnet traction systems will be realized in the future, and information management will be carried out on the status monitoring, health management and life prediction of permanent magnet motors."
Chen Huiqing, Deputy Secretary of the Zhuzhou Municipal Party Committee and Acting Mayor, stated that Zhuzhou will insist on taking permanent magnet power as a key strategic emerging industry, build a permanent magnet application technology platform, build a permanent magnet product manufacturing base, and improve the permanent magnet power industry chain. Greatly form new industrial development advantages.
