In this study, we proposed a hybrid stator comprising a superconductor and a ring-shaped permanent magnet and measured the oscillation characteristics of a magnet levitating above various hybrid stators. By adding a ring magnet, the vertical magnetic attractive force and stiffness were increased compared with those of a simple superconducting stator. The oscillation frequency of the hybrid stator is higher than that of the simple superconducting stator. The proposed hybrid stator exhibits better oscillation characteristics than a simple superconducting one. An improvement in the stability of the levitating magnet is realized by the hybrid stator using a superconductor and a ring-shaped magnet.
