Jiangsu Jiaxuan+Baotou Rare Earth Research Center | Held an academic seminar on permanent magnet motors
Recently, Jiangsu Jiaxuan and Baotou Rare Earth R&D Center held an academic seminar on the theme of "permanent magnet motor". Chairman of Jiangsu Jiaxuan, chief engineer of R&D technology, deputy engineer, marketing director, and leading representatives of Professor Guo Yongmei from Rare Earth Research Institute attended the academic seminar.
This academic seminar will focus on discussing the development of "intelligent high-performance rare earth permanent magnet motor" under the dual carbon background, and show the latest technology development trend and research achievements in the field of rare earth permanent magnet motor. It aims to further strengthen the cooperation and exchange in the field of permanent magnet motors and permanent magnet materials, and better promote the technical progress and industrial development of China's permanent magnet motors and permanent magnet materials industry.
In the seminar, Marketing Director Dong Jiwen made a report entitled "New Technology Development Frontier of Permanent Magnet Drive Motor", introduced the development history and technical characteristics of permanent magnet motor, as well as the application status of permanent magnet motor in belt conveyor, slag vertical mill, ball mill, elevator and other equipment and application cases in various industries, and pointed out the future development direction of permanent magnet motor drive technology.
Professor Guo Yongmei and his delegation pointed out that "industrial motors consume a lot of energy, accounting for 60% of the power consumption of the whole society. Compared with ordinary motors, permanent magnet motors made of permanent magnets can save about 20% of the power, and are praised as" energy saving artifact "in the industry. During the "Fourteenth Five Year Plan" period, the main goals of economic and social development include: remarkable achievements in green transformation of production and lifestyle, more rational allocation of energy resources, significant improvement in utilization efficiency, and reduction of energy consumption and carbon dioxide emissions per unit of GDP by 13.5% and 18% respectively. At present, permanent magnet motors account for less than 15% of the motor industry in the domestic market. Therefore, the market scale of permanent magnet motor will be huge in the next 5-10 years.
Permanent magnet motor products are in line with the first-class energy efficiency. Experts pointed out that "the first class energy efficient motor saves 203000 yuan a year compared with the third class energy efficient motor."
Jiaxuan intelligent industrial motors have been certified as China's energy-saving products, and the energy efficiency grade of 131 products is Grade 1. Through long-term on-site application, it can be proved that permanent magnet motors can achieve 8% - 50% energy saving effect compared with asynchronous motors in different processes. Ren Zhiqiang, deputy director of the National Energy Conservation Center, said: Data shows that every percentage point increase in the energy efficiency of motors in the industrial field can save up to 26 billion kilowatt hours of electricity annually. If the efficiency of the motor system is improved by 5-8 percentage points, the electricity saved every year is equivalent to the power generation of 2-3 Three Gorges Power Plants.
As of 2021, the carbon footprint of Jiaxuan permanent magnet products has far exceeded the industry level. Up to now, the energy saving rate is 20% - 30%, the cumulative coal saving is 9.76 million tons, the carbon dioxide emission reduction is 25.585 million tons, the sulfur dioxide is 8.3 million tons, and the nitrogen oxide is 7.21 million tons.
