Technical analysis of magnetic suspension blower bearing

With the integration of electronic components and the development of control theory and rotor dynamics, great progress has been made in the research of Maglev blower shaft technology at home and abroad. However, whether in theory or in the process of commercialization, this technology has many problems.

The problems to be solved for the maglev blower shaft are mainly manifested in the control system and the dynamic characteristics of the rotor shaft system. While paying attention to the research of the control system, the rotor dynamics analysis of the system is emphasized, so as to improve the control method and strategy more effectively; Sliding mode control, fuzzy control and neural network control with strong robustness are used to control the complex rotor dynamic characteristics.

The overall level of magnetic levitation blower shaft technology in China has reached the engineering application level. After the application of electromagnetic suspension bearing, the structure should be reformed. From the current technical level, the application of domestic electromagnetic suspension bearing technology in room temperature equipment should be qualified.
