On November 10,2022, the world’s first experimental prototype of a permanent magnetic suspension bearing for wind turbines, developed by Meigher Na Magnetic Power Co. , Ltd. , was successfully launched in Changchun.

    Ma Zhongwei, chairman of the board of directors, said: This is a new bearing technology line opened up by Magna to ensure the safety of the national wind power industry chain, to make bold innovations, to break through the bottleneck of wind power spindle bearing technology. This technology makes full use of the characteristics of non-contact energy transfer of magnetic field force, through multi-stage magnetic circuit optimization design, accurate control of bearing capacity, the traditional contact transmission into non-contact suspension transmission, to achieve ultra-low power loss, improve the efficiency of wind power generation equipment. Focus on solving the problems of wind power equipment, such as vibration, noise, life, to reach no contact, low vibration, long life. At present, it has obtained 3 invention patents and 17 utility model patents.

    With the rapid development of new energy demand, wind power equipment supply chain brings many challenges. Among them, the wind power spindle bearing has become the most important bottleneck restricting the development of the wind power industry. At present, about 98% market share of main shaft bearings of wind power above 6MW class is occupied by import enterprises, and only 32% market share of 3-6MW class is occupied by domestic bearing enterprises, and most of them are concentrated in low-power class, the main shaft bearing developed by meagre sodium can satisfy the application range of 1MW to 30MW wind power main shaft bearing, and has many advantages. It is of great significance to get rid of import dependence of wind power main bearing and protect the safety of national wind power industry chain.

   This year is also the 10th anniversary of the start-up of Magna, Ma said. On the basis of maintaining the leading level of permanent magnetic speed governor and permanent magnetic coupling at home and abroad, MEAGNA actively responds to the call of the country to develop new energy sources, and boldly targets the next development goal at the main bearing of wind power generation, we have created a new“Magnet”, which helps the healthy development of the new energy industry. With the successful start-up of the prototype of the permanent magnetic bearing for wind power, Magna will step into a new stage of development and accelerate the technological innovation and application industrialization of the wind power permanent magnetic bearing products in the future, and the continuous development of breakthroughs in the application of nuclear power main pumps, hydraulic turbines, flywheel energy storage, steam turbines and other major national key areas, to provide key technical support for the country's major core equipment, to help the country's industrial transformation and upgrading, will continue to focus on the national“14th five-year plan” development strategy, the country's major needs, the implementation of the mission of Magna.
