In recent years, with the continuous advancement of science and technology, magnetic levitation technology is emerging in many high-tech fields. From implantable artificial heart pumps to rotorcraft, to gas turbines and other equipment, the application of magnetic levitation technology is becoming more and more extensive. In these systems, magnetic levitation bearings, as key components, play an irreplaceable role.

Magnetic levitation bearings are different from traditional mechanical bearings. They use electromagnetic force to achieve contactless suspension of the rotor, thereby avoiding friction and wear. They have many advantages such as high efficiency, energy saving, low noise, and long life. This feature makes it particularly prominent in fluid machinery such as compressors, blowers, and centrifugal units.

Relevant person in charge of the China Machinery Industry Federation pointed out that magnetic suspension bearings are not only one of the important indicators of the technical level of high-end equipment, but also one of the core technologies to promote the development of industry towards green and intelligent directions. At present, my country has promoted the use of magnetic suspension blowers, compressors and other equipment in many key industries such as building materials, petrochemicals, and metallurgy, saving more than 50 billion kilowatt-hours of electricity annually, equivalent to reducing carbon dioxide emissions by about 40 million tons, with significant energy-saving and emission reduction effects.

Although magnetic suspension bearings have broad development prospects, their large-scale promotion and application still face challenges. Experts from Nanjing University of Aeronautics and Astronautics pointed out that this technology involves multidisciplinary intersections, the design and manufacturing thresholds are high, and it is difficult to standardize and serialize products. In addition, problems such as limited carrying capacity, reliability to be improved, and high cost also restrict its popularization speed.

Researchers from Tsinghua University said that in the future, with the development of high-performance materials, the introduction of intelligent monitoring systems, and the optimization of control algorithms, the performance of magnetic suspension bearings will continue to improve, and it is expected to break through the current technical bottleneck.

In order to accelerate industrial development, industry experts suggest that the construction of a collaborative innovation system should be strengthened, basic research and engineering applications should be promoted, and key technologies such as core materials, sensor components, and precision machining should be focused on. It is also necessary to improve the standard system and testing and certification platform, promote the establishment of a professional talent training mechanism, and expand more demonstration application scenarios, such as urban rail transit energy storage systems, medical equipment, and aerospace.

Overall, magnetic bearings are gradually becoming an important support for industrial energy conservation and upgrading. With the continuous advancement of policy support and technological progress, they will play a more important role in the future green transformation of the manufacturing industry.
