As an extension of the world-renowned construction machinery exhibition, Bauma, Germany, Bauma CHINA has become a competitive stage for global construction machinery companies. On this stage, many high-quality companies gathered, exhibited tens of thousands of innovative products and technologies, and witnessed the inheritance of the wisdom of construction machinery.

At Bauma Exhibition in 2020, the world's first 630KW permanent magnet electric drum was unveiled. This product was developed and manufactured by JASUNG Intelligent Industry. The 630KW series permanent magnet direct drive electric drum of Jiaxuan Intelligent Industry adopts permanent magnet motor technology. Drive transmission technology, external rotor motor technology, combined with a new type of drive equipment designed to drive rollers, are suitable for driving various types of belt conveyors. Through the innovative design of the stator teeth and yoke separation structure, the torque density of the permanent magnet outer rotor motor is improved, and the problem of low torque density is solved. It has a high-efficiency cooling system with a low-speed and high-torque external rotor permanent magnet direct-drive drum. Effectively avoid excessive local temperature rise; the heat dissipation calculation model of the stator punched silicon steel is proposed, and the original punched fin is used as the heat dissipation channel carrier, which effectively saves space and improves the cooling capacity of the low-speed and high-torque outer rotor permanent magnet direct-drive drum With torque density and torque density, the total transmission efficiency can reach 94.9%. It has excellent start-up, speed regulation characteristics and energy-saving effects, and has broad application prospects and economic and social benefits. 

JASUNG permanent magnet drum is characterized by simple structure, stable and efficient, stable operation, energy saving, environmental protection, and space saving, and is gradually promoting the development of belt conveyor drive innovation. Jiaxuan's permanent magnet drum has been running stably for more than 25,000 hours, proving that it has become the top-level technology for belt drive.

In the future, coal, cement, steel, metallurgy and other industries will not only realize automated and intelligent mining, but also follow the pace of the energy revolution, achieve precise mining, and use cutting-edge technologies to promote the formation of a set of advanced warning and precise identification mining methods. The ultimate goal is to liberate manpower from underground mines, mining sites, and high-risk workplaces, so that coal, cement, steel, metallurgy and other industries can become truly safe industries.
