Development of a magnetically suspended double-layered cylinder with 1-DOF active positioning control

A magnetically levitated double-layered cylinder has been developed for windage loss reduction of the high speed spindle that is rotating inside the inner cylinder. An axial position of each cylinder is actively controlled whereas radial and tilting motions are passively stabilized by the magnetic c...
