Abstract
Magnetic suspension technology, as an emerging supporting method, has demonstrated significant application potential in the field of high-speed rotating machinery in recent years. Conventional mechanical bearings encounter issues such as substantial friction loss and low reliability under high-speed operating conditions, whereas magnetic suspension technology effectively addresses these challenges through non-contact support. This study aims to investigate the current application status of magnetic suspension technology in high-speed rotating machinery, examine its technical challenges, and propose improvement strategies to enhance its performance and stability. By integrating theoretical analysis with experimental validation, this research conducts an in-depth study on the dynamic characteristics of magnetic suspension systems, optimization of control algorithms, and energy consumption performance. The results indicate that systems based on active magnetic suspension technology can significantly reduce mechanical losses, improve operational efficiency, and extend the service life of equipment. However, existing technologies still exhibit deficiencies in cost control, adaptability to complex operating conditions, and long-term operational stability. This paper innovatively proposes an adaptive control algorithm capable of effectively addressing load fluctuations and external disturbances, thereby substantially enhancing system robustness. Furthermore, by optimizing the design of magnetic suspension bearings, energy consumption levels are further reduced. Overall, this study provides theoretical support and technical references for the extensive application of magnetic suspension technology in the field of high-speed rotating machinery, laying a foundation for its future development direction.
