China first magnetic bearing positive pressure case generator is launched
The latest news shows that Harbin Electric corporation Jiadian Co., Ltd. Advanced Motor Company has successfully completed a groundbreaking technical project - "TFYZY 150-2/12000 positive pressure shell type high-speed permanent magnet synchronous generator and magnetic suspension drive control system", and passed the expert review on December 12. This breakthrough means that China has taken an important step in the field of magnetic suspension bearing technology and achieved independent control of core technology.
According to the feedback from the review committee, Harbin Electric Group has mastered the complete design, manufacturing and commissioning process of magnetic suspension bearings and their control systems, and has successfully developed products with completely independent intellectual property rights. It is particularly noteworthy that this high-speed (12,000 rpm) positive pressure shell type permanent magnet synchronous generator equipped with magnetic suspension bearings is the first product in China to apply such technology, and its efficiency is at the leading level in China.
Magnetic bearings are high-tech components that use electromagnetic force to achieve non-contact support. They are precision electromechanical products. Compared with traditional mechanical bearings, it eliminates physical friction and brings significant advantages such as higher rotation speed, longer service life, no need for lubrication, no oil pollution, and lower noise and vibration.
In addition, one of the core technologies of magnetic bearings is its control system, which uses the principles of magnetic field and electromagnetic induction to accurately support and stabilize the rotating axis without direct contact with rotating parts, allowing the equipment to operate efficiently under high-speed conditions. operation while maintaining high accuracy. This technology not only improves the performance of mechanical equipment, but also shows broad application prospects in many key industries such as high-speed turbines, waste heat power generation, petrochemicals, nuclear energy utilization, and transportation.
