“…It features noncontact, high-speed movement and high-velocity revolution and enables the easy formation of a levitation system. Therefore many fundamental studies such as analysis of vibration problem, vibration control, etc., have been published so far [1]- [5]. However, in case of using the existing motor technology as a drive for the high-Tc superconducting levitation system, the levitation and the drive are achieved by combining a permanent magnet which is magnetized in the direction of the thickness and a multipoled permanent magnet.…”

In this research, it proposes the development of High-Tc Superconducting Levitation compact flywheel. The permanent magnet magnetized in the thickness direction where the sectorial magnetic material plate is adsorbed creates the multipole field outside of the magnet. The levitation body achieved the stable rotation without the control by giving the driving force from the axial direction to the multipole field of the levitation body, and thus it succeeded in riding past the resonance. And, the voltage correction that considered the counterelectromotive force and impedance was executed so that this system might obtain the stable torque. As a result of measurement of electric power generation at the high-speed rotation region, it was confirmed that this system had about 84% conversion efficiencies. The result of the experiment and the theoretical value of the magnetic flux density, the torque, the frequency response, and the conversion efficiency of this system were compared. As a result, because measurements and the analytic value were corresponding well, it was confirmed that this analysis was useful.
