On September 3, 2020, the China Machinery Industry Federation organized experts to appraise the scientific and technological achievements of the "Efficient Intelligent Permanent Magnet Direct Drive Roller" completed by Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd. Due to the good economic, social and environmental benefits brought by the Jiaxuan Intelligent Permanent Magnetic Roller, the appraisal committee believes that the project results have reached the international leading level and agreed to pass the appraisal of scientific and technological achievements. The committee also recommended that Jiaxuan actively promote the industrial application of smart permanent magnet rollers.

This time it has been recognized by an authoritative organization, and Jiaxuan's leading technical strength is self-evident. The intelligent permanent magnet roller can obtain the certificate of scientific and technological achievements, and the main innovations are as follows.
First, Jiaxuan invented a high-power, high-torque density, low-speed, high-torque, external rotor intelligent and efficient permanent magnet direct drive electric drum, studied the nonlinear characteristics of the DC magnetization of cold-rolled silicon steel sheets, and proposed the external rotor permanent magnet The optimal operating point analysis method of the permanent magnet of the magnetic drum, through the innovative design of the stator teeth and yoke separation structure, has realized the improvement of the torque density of the permanent magnet outer rotor motor and solved the problem of low torque density. 

Second, Jiaxuan has developed a high-efficiency cooling system for low-speed and high-torque external rotor permanent magnet direct-drive drums. Based on the low-speed and high-torque external rotor permanent magnet direct drive drum temperature field distribution law, a wave-shaped diversion design method in a limited space is proposed to effectively avoid excessive local temperature rise; a heat dissipation calculation model for the stator punched silicon steel is proposed, using The remaining material of the original punching film is used as the heat dissipation channel carrier, which effectively saves space and improves the cooling capacity and torque density of the low-speed and high-torque outer rotor permanent magnet direct-drive drum. Third, Jiaxuan has established a deep learning-based low-speed external rotor permanent magnet direct-drive drum intelligent operation and maintenance technology, with deep learning diagnosis algorithms, operation and maintenance intelligent algorithms, and remote operation and maintenance functions; it uses artificial intelligence models to achieve abnormality detection and failure Diagnosis, research and development of automatic grease maintenance function based on vibration, temperature and other physical quantities, realize remote operation status viewing and control and intelligent diagnosis, and improve the reliability of operation. Fourth, tested by a third-party testing agency, the efficiency of the 315KW three-phase permanent magnet synchronous drum motor reached 94.9%. The on-site operation shows that the system is stable in operation, reliable in performance, and has good economic, social and environmental benefits.

Excellent technology can speak by itself, and good products will blossom by themselves
Once the Jiaxuan Intelligent Permanent Magnet Roller was launched, it received a large number of market orders. Previously, the Belt Conveyor Branch of the Electromechanical Safety Professional Committee of the China Coal Industry Safety Science and Technology Society issued a certificate: In 2019, Jiangsu Jiaxuan's intelligent permanent magnet direct drive drum products ranked first in the national market share! Combining these two honors, it can be seen that Jiaxuan has established an industry leader's market position in the field of industrial rollers, leading the industry's technology benchmarks.
Science and technology are the primary productive forces. Only insisting on innovation is the foundation. The reform of my country's coal industry has a long way to go. As a practitioner of technological innovation, Jiaxuan is also a participant in the changes of the times, and is actively making its own contributions.
