Brief introduction: On November 10, 2022, the world's first typhoon electro-permanent magnet suspension spindle bearing experimental prototype with fully independent intellectual property rights developed by Magna Magnet

On November 10, 2022, the world's first typhoon electro-permanent magnet suspension spindle bearing experimental prototype with fully independent intellectual property rights developed by Magna Magnetic Power Co., Ltd. was successfully launched in Changchun.

Chairman Ma Zhongwei said: This is a new bearing technology route opened up by MagNA to ensure the safety of the national wind power industry chain, make bold innovation and break through the technical bottleneck of wind power spindle bearing. This technology makes full use of the characteristics of non-contact energy transfer of magnetic field force. Through multi-stage optimization design of magnetic circuit and precise control of bearing capacity, the traditional contact transmission is transformed into non-contact suspension transmission to achieve ultra-low power loss and improve the power generation efficiency of wind power equipment. Focus on solving the vibration, noise, life and other problems plaguing wind power equipment, to achieve no contact, low vibration, long life. At present, we have obtained 3 invention patents and 17 utility model patents.

At present, with the rapid growth of new energy demand, it brings many challenges to the supply chain of wind power equipment. Among them, wind power spindle bearing has become the main bottleneck restricting the development of wind power industry. At present, about 98% of the market share of domestic wind power spindle bearings above 6MW is occupied by imported enterprises, while domestic bearing enterprises only occupy about 32% share in 3-6MW, and most of them are concentrated in small power levels. There is a big gap between them and imported bearings in key parameters such as life and capacity. The spindle bearings developed by Magna can meet the application range of 1MW to 30MW wind power spindle bearings, which has many advantages. It is of great significance to get rid of the import dependence of wind power main bearings and protect the safety of the national wind power industry chain.

Ma pointed out that this year is also the 10th anniversary of Sodium Magnuma. On the basis of maintaining the leading level of permanent magnet governor and permanent magnet coupling at home and abroad, Magsodium actively responds to the call of national development of new energy, and boldly targets the main bearing of wind power generation as the next development target, innovates a new "magnetic heavy", and promotes the healthy development of new energy industry. With the smooth start of the wind power permanent magnet suspension spindle bearing prototype, Magna will also enter a new stage of development. In the future, it will accelerate the technological innovation and application industrialization of wind power permanent magnet suspension spindle bearing products, and successively develop application breakthroughs in key national fields such as nuclear power main pump, water turbine, flywheel energy storage, and steam turbine. To provide key technical support for national key core equipment and help national industrial transformation and upgrading, we will continue to focus on the national "14th Five-Year Plan" development strategy and meet the major needs of the country, and fulfill the mission of Magna.
