On August 7, 2019, the project results of "Belt Conveyor Permanent Magnet Direct Drive Electric Roller Technology" passed by Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd. were appraised in Beijing.

The results appraisal meeting was organized by the China Machinery Industry Federation. The appraisal committee was composed of members from China Electrical Equipment Industry Association, China National Machinery Industry Corporation, China Coal Society, China University of Mining and Technology (Beijing), University of Science and Technology Beijing, and National Safety Production Shanghai Mining Equipment It consists of 7 experts from the Testing and Inspection Center and Kailuan (Group) Co., Ltd., and Professor Chen Weihua of China Electrical Equipment Industry Association serves as the chairman of the Appraisal Committee. The project leader Zhang Chunhui, the complete set department Fu Guanghong, the R&D department Zuo Cheng, and the external relations department Liu Yifan respectively reported on the project’s R&D and application of the results. The appraisal committee reviewed the technical data such as the product test report and the novelty search report. Discussion and questioning: The technology is innovative and has significant energy-saving effects. It has reached the leading domestic level in terms of high-power, high-efficiency, low-speed, high-torque belt conveyor permanent magnet direct-drive electric rollers in the coal industry, and agreed to pass the appraisal.

The permanent magnet direct drive drum motor technology of belt conveyors is a cutting-edge drive technology, which has the characteristics of high efficiency, energy saving, reliable system, large torque direct drive, and intelligence. It is the development direction of belt conveyor transmission technology and has broad Application prospects. In recent years, as a national high-tech enterprise, Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd. has relied on the national safety production Shanghai mining equipment testing and inspection center to design and develop test benches and other conditions. The demand for driving electric drum technology has been extensively studied in this field, and outstanding results have been achieved, filling the country’s technical gap in this field. The research and development of permanent magnet direct drive electric drums and other series of products have been widely used in coal mines and metallurgy.

  Jiaxuan Intelligent has developed a complete series of permanent magnet direct-drive electric drum products, covering all specifications of coal safety 315KW, non-coal safety 630KW and below; the only full-frequency full-load permanent magnet direct-drive electric drum testing equipment for 630KW; and Shanghai Coal Science Testing Technology Co., Ltd., Anbiao National Mining Product Safety Marking Center Co., Ltd. and other units jointly drafted and compiled the "Explosion-proof Three-phase Permanent Magnet Synchronous Drum Motor Industry Standard for Mines", which will promote the technology of permanent magnet direct drive electric drums. The promotion and application in the field of belt conveyors has played an important role in promoting.
