Abstract
Aim: This study aims to analyze the influence of harmonic excitations during bearing misalignment on the power and mechanical characteristics of a high-speed magnetic bearing based on tape high-temperature superconducting composites.
Methods. Numerical multiphysics analysis of a superconducting magnetic bearing was performed using the finite element method in Comsol Multiphysics.
Results. When there is a deviation from coaxiality in the arrangement of the magnetic elements of the HTS bearing, harmonic excitations, vibrations, and beats appear, leading to a deterioration in the load characteristics of the device and a decrease in the dynamic permeability of the magnetic system.
Conclusion. The developed numerical model makes it possible to predict the dynamic and mechanical characteristics of high-speed HTS bearings and can be used to develop high-speed rotor systems.
