On December 26, 2019, the Jiangsu Provincial Joint Conference Office for the Promotion and Application of New Technologies and Products formally announced the provincial key promotion and application catalog (the 22nd batch). The permanent magnet direct drive electric drum technology independently developed by Jiangsu Jiaxuan has been selected and verified by experts in the industry, and has been successfully included in the catalogue.
Established in 2005, Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd. is mainly engaged in the maintenance of bulk material conveying systems and the development and application of intelligent industrial motor application technologies. In 2015, in response to the "Made in China 2025" policy, it began to invest in research and development of permanent magnet direct-drive electric drums, contributing to improving the country's manufacturing innovation capabilities, promoting green manufacturing, and promoting breakthrough development in key areas. After countless days and nights of struggle, Jiaxuan people have developed a permanent magnet direct drive electric drum with sweat and wisdom. The intelligent and energy-saving permanent magnet roller has won numerous praises from industry experts. In May 2018, it was called "the third revolution of the belt conveyor industry" by experts in the belt conveyor industry at the Beijing International Coal Exhibition in May 2018. The advantages of permanent magnet direct drive electric drums are high-power drive, wide application range, high energy saving rate, long life, high safety, simple structure, small size, small maintenance, and low operating costs.

In 2019, the General Department of the National Energy Administration issued the "Announcement of the Proposed Industry Standard Project in the Energy Field in 2019". Regarding the "Explosion-proof Three-phase Permanent Magnet Synchronous Electric Drum for Mines", JASUNG, as the author, officially operated with Shanghai The Coal Testing Center cooperated in the research and development and design of the country’s most advanced intelligent instrument test bench (the only test instrument in the country). In August 2019, JASUNG won the domestic leading technology appraisal; in December, it was entering the "National Industry Recommended Catalogue of Energy-saving Technology and Equipment (2019)" and "National Industrial Energy-saving Technology Application Guidelines and Cases (2019)".

After the continuous improvement of technology and process in the later stage of JASUNG permanent magnet drum, the permanent magnet direct drive electric drum technology has been continuously improved, and successfully entered this "provincial key promotion and application of new technology and new product catalog (the 22nd batch) )". The people of JASUNG will still be committed to the most cutting-edge scientific research and innovation with a tenacious will, and lead the operation and development of the company with "technological innovation" as the guide, making JASUNG the pride of the world's brand and clan.
