A new magnetic suspension using a variable flux-path has been proposed. The flux of the permanent magnet to floator is controlled by moving ferromagnetic plates between them. The lateral position of ferromagnetic plates is changed by an actuator. In the previous works, a 100-g steel ball was supported and controlled in three dimensions using this mechanism. The purpose of this study is to suspend a kg-order object and controlled it in three dimensions. This study shows that a one-kg steel ball can be supported by magnetic suspension using a variable flux-path mechanism.
