Notes:
A two dimensional proximity sensor system was used to study dynamics and magnetic unbalance effects of superconducting magnetic bearings. Both dynamic stiffness and vibration damping were found to increase with decreasing bearing gap. Lateral vibrations of an aluminum disk integrated into a superconducting flywheel system were measured during free rotation. From the measurements, the magnetic unbalance was deduced and it is shown that related effects, such as bearing losses and instability at the critical, can be reduced significantly by shifting the center of gravity of the disk assembly towards the magnetic symmetry axis. © 1996 American Institute of Physics.
