AI Technical Summary

Technical Problem

The existing electromagnetic bearing rotor and sensor rotor structure of the main helium blower are welded, which is prone to weld cracking and deformation, resulting in uneven gaps, complex and unstable assembly, and affecting the reliability and stability of the electromagnetic bearing system.

Method used

An integrated electromagnetic bearing rotor and sensor rotor structure was designed. By combining the electromagnetic bearing rotor bracket, rotor pressure plate and adjusting fasteners, and using the lamination outer diameter positioning and heat fitting method, the assembly process is simplified and the overall connection of the rotor is ensured to be stable.

Benefits of technology

This achieves a stable connection between the electromagnetic bearing rotor and the sensor rotor, avoiding welding deformation and assembly gaps, ensuring accurate position sensor signals, stable operation of the electromagnetic bearing system, and extending the service life and reliability of the main helium blower.
