Abstract

Based on the Meissner effect a superconducting hollow sphere rotor is levitated in the vacuum housing. During the high speed rotation, the dynamic deformations caused by the centrifugal force will generate magnetic disturbing torque on the superconducting rotor. The deformations of the rotor are analyzed and simulated by finite-element method, and the deformation laws are obtained. The structure of spherical-like rotor is designed to compensate the centrifugal deformation at the high rotational velocity. It has significant theoretical value for the design and optimization of the rotor structure.
