Abstract
In this study, changes in levitation characteristics were investigated by modifying the combination of high-temperature superconductors with groove and step geometry in addition to the magnetic circuits. The levitation characteristics were verified by analyzing the restoring force and vibration characteristics of the fabricated superconducting magnetic bearings in each direction. The experimental results confirmed that the restoring force characteristics and vibration damping were improved by appropriately arranging the groove and step geometry in relation to the magnetic flux gathering area. The experiments showed the usefulness of modifying the geometry and the magnetic circuits.
