In May 2021, Anhui Mingteng Permanent-Magnetic Machinery & Electrical Equipment Co.,Ltd made a major technical breakthrough in the development of high power high voltage super efficient three-phase permanent magnet synchronous motor, and successfully independently developed 5300 kW high voltage super efficient three-phase permanent magnet synchronous motor, which was officially put into use in the slag mill system of Shandong Rizhao Lupi New Materials Co. This is the application of China’s 5300 kW high-power high-voltage super-efficient three-phase permanent magnet synchronous motor in the industrial field, which shows that Anhui Mingteng Permanent Magnet Electromechanical Equipment Co., Ltd. has the leading technical level in developing permanent magnet synchronous motor in the industrial field, and also marks the opening of the era of permanent magnet motor above 5 MW in China.
Anhui Mingteng Permanent-Magnetic Machinery & Electrical Equipment Co.,Ltd(https://www.mingtengmotor.com/)is a modern high-tech enterprise integrating R&D, manufacturing, sales and service of permanent magnet motors. After fully understanding the working characteristics and working environment of slag mill in cement industry, Anhui Mingteng Permanent-Magnetic Machinery & Electrical Equipment Co.,Ltd has developed and produced the 5300 kW high-voltage super-efficient three-phase permanent magnet synchronous motor completely independently by the company, which has made innovations and breakthroughs in a number of technologies:
(1)Optimized electromagnetic design, the stator and rotor core material is made of high performance cold-rolled silicon steel sheet, which suppresses high frequency iron consumption and improves efficiency.
(2) Adopt end-cap sliding bearing structure, high load capacity, low noise and vibration, high reliability, easy to use and maintain, enhance the load capacity of the motor, especially the superior anti-vibration load capacity.
(3)Selecting the slot fit, preferably stator slot ratio, effectively reducing the motor slot torque and reducing the motor noise.
(4)Adopt IC666 cooling method, both internal and external air circulation rely on the cooler fan to enhance the cooling effect and effectively reduce the motor temperature rise.
(5)The rotor shaft adopts welded spoke plate structure to enhance the rotor stiffness and reduce the vibration value of the whole machine.
Compared with induction motor, permanent magnet motor is a motor that uses permanent magnet material to establish magnetic field and does not need reactive excitation current to establish magnetic field, which has high efficiency and power factor, good starting torque performance, low noise, low vibration, temperature rise, etc. It is a high-efficiency motor promoted by the state. China’s motor holdings of about 2 billion kilowatts, the vast majority of motors in use is the Y series to eliminate backward asynchronous motors, high-efficiency motors account for only about 3%, the use of a large number of inefficient motors caused a huge waste of electricity.
“Made in China 2025″ five major projects in the comprehensive implementation of green manufacturing project pointed out that we should continue to improve the energy efficiency of motors and other end-use products, and accelerate the elimination of backward mechanical and electrical products and technologies. The 5300 kW high-voltage super-efficient three-phase permanent magnet synchronous motor developed and used in this project has promoted the pace of China motor energy efficiency improvement and provided strong theoretical support for the concept of carbon peaking and carbon neutrality proposed again at this year’s two sessions. In addition, in this project, compared with the original drive system, it not only improves the efficiency, but also adopts frequency converter with the start, which can realize the infinitely adjustable speed operation, reduce the impact with the equipment, and also can adjust the speed at any time to meet the needs of the working condition and reduce the waste of energy consumption.
Do not forget the original intention, forge ahead. Anhui Mingteng Permanent-Magnetic Machinery & Electrical Equipment Co.,Ltd actively responds to the China call for energy saving and emission reduction, always insists on research and development, promotes the application of permanent magnet motor in the industrial field as the goal, and constantly develops permanent magnet motor with higher efficiency, higher power and wider range, and the application of permanent magnet motor in more fields and wider range will become an inevitable trend.
