Stabilization of magnetic repulsive levitation system by superconducting magnetic bearing

摘要：

　　In this research,we invented and produced a Superconducting magnetic bearing using repulsive permanent magnet.The repulsive magnetic levitation system with permanent magnet can generate strong levitation force without power supply.However,it is unstable except in the repulsion direction.In contrast,superconducting magnetic bearings can generate restoring force in all directions by utilizing the property of magnetic flux pinning of superconductors.Therefore,we constructed a superconducting magnetic bearing(SMB)which is stable in all axis without control and has a strong axial levitation force by combining a repulsive type magnetic levitation system and a superconducting magnetic levitation system.Furthermore,the driving test of the flywheel incorporating the SMB was carried out to verify the characteristics of the SMB.As a result of the experiment,it was confirmed that the flywheel could overcome the resonance and drive it.The maximum rotation speed of the flywheel was 10000rpm.
