Abstract: In this report, a stabilization method for a
repulsive-type magnetic levitation system using a superconducting magnetic
bearing is proposed. A repulsive-type magnetic levitation system can
generate a large levitation force. However, this system is unstable since
there is no horizontal stabilization and moment of force without control.
Incidentally, a high-temperature (high-Tc) superconducting magnetic bearing
can always stabilize levitation without control. Moreover, it is possible to
cancel the unstable force of repulsive-type magnetic levitation by
increasing the rigidity of the high-Tc superconducting bearing. In this
study, the unstable force of repulsive-type magnetic levitation was
stabilized by combining these two methods. In addition, the levitation
system generated a large levitation force.
