september 8. The 2018 China permanent magnet drive technology seminar was held in Zhuzhou. More than 300 academicians, experts and scholars gathered together to discuss the development direction and application fields of permanent magnet drive technology around the theme of the permanent magnet era of modern transportation, so as to provide suggestions for promoting industry development and technological progress

this technical seminar is co sponsored by China Urban Rail Transit Association and CRRC. Jointly undertaken by experts and Academic Committee of China Urban Rail Transit Association, Zhuzhou CRRC times Electric Co., Ltd. and Changsha rail transit Group Co., Ltd

more than 300 academicians, experts and scholars, including qianqingquan, liuyoumei, sunfengchun and dingrongjun, academicians of the Chinese Academy of engineering, hezhaohui, vice mayor of Zhuzhou, songminhua, vice president and Secretary General of China Urban Rail Transit Association, and yangwenhao, Secretary General of China Rare Earth Industry Association, attended the seminar to contribute to the development of China's permanent magnet drive technology, The meeting was chaired by lizhonghao, an expert of China Urban Rail Transit Association and deputy director of Academic Committee. Wang Jun, vice president of CRRC, lidonglin, chairman and Secretary of the Party committee of the company, fengjianghua, deputy general manager and chief engineer of the company, liukean, general manager of times electric, and other leaders attended the seminar

this seminar is in the form of conference special report + thematic group discussion. Academician sunfengchun discussed the relationship and future between permanent magnet drive technology and the development of new energy vehicles with the theme of electric drive technology and new energy vehicles; Dr. dongshengzhi, chief expert of China Steel Research Technology Group Corporation, introduced the latest research and application results of system permanent magnet materials with the theme of "rare earth permanent magnets are measured by experimental equipment; research and application of magnetic materials"; Fengjianghua, deputy general manager and chief engineer of the company, takes the trend and Prospect of permanent magnet traction system for rail transit as the theme, and expounds the application background of permanent magnet traction system in rail transit system and the length trend between gauge lengths of fractured specimens measured with vernier caliper; Xiaolijun, deputy chief engineer of Changsha rail transit Group Co., Ltd., with the theme of "demonstration application of urban rail permanent magnet traction system in Changsha Rail Transit Line 1", introduced the demonstration application of permanent magnet traction system in Changsha Metro Line 1, and expounded the application prospect of permanent magnet traction system in the Metro field

this seminar has rich topics, involving key permanent magnet devices and materials, rail transit permanent magnet technology, electric vehicle permanent magnet technology, industrial application technology of permanent magnet system and other fields. Academicians and scholars' strategic views on technology have clarified the bright prospects and future of permanent magnet technology. The achievements of enterprise technical experts on the practical application of permanent magnet technology have pointed out the possibility for the application of permanent magnet technology in various fields, which will help promote the exchange and development of permanent magnet drive technology, and strengthen the application of permanent magnet drive technology in rail transit, new energy vehicles, wind power generation, central air conditioning and other industrial fields, Expand the sustainable development of China's transportation equipment technology to other industrial fields

permanent magnet drive technology is a new generation of traction technology. It uses magnetic force to drive the load, so as to realize non-contact torque transmission between the motor and the load. As the permanent magnet drive technology has the advantages of low carbon, energy saving, safety, reliability, green and environmental protection, it is considered as the future development trend. Permanent magnet drive technology has been born for a long time, and has been developed mature, and has been applied in electric vehicles, wind power, ships and other fields. With the maturity of the technology, in recent years, the permanent magnet drive technology has begun to expand to the fields of rail transit, electric vehicles, industrial automation and so on

2003, Zhuzhou Institute took the lead in the research of permanent magnet synchronous traction system in the field of rail transit in China. In 2008, Zhuzhou successfully realized the first application of permanent magnet synchronous traction system on the electric bus. In 2016, the first permanent magnet Metro in China was officially put into passenger carrying operation in Changsha Metro Line 1, opening the permanent magnet era of urban rail transit in China. Permanent magnet Metro is not only more efficient, lower noise, but also more energy-saving and environmental protection. According to authoritative tests, it increases its mechanical properties through appropriate heat treatment process, and the comprehensive energy saving reaches 30%. The economic benefits are very considerable, and the social benefits are very significant. In 2018, the first domestic permanent magnet high-speed EMU loaded with the core components of Zhuzhou Research Institute completed the 300000 km operation assessment, with stable performance. It is expected to receive the batch application approval from China Railway Corporation in the future. The successful application of permanent magnet drive technology in the field of rail transit has broken the blockade and monopoly of foreign countries, filled the gap in China's independent research and development of urban rail transit permanent magnet traction system trains, and played a positive role in promoting industrial development and building an energy-saving, green and low-carbon ecological livable city
