Vibration reduction in a hollow-shaft rotor using flexibly-mounted internal-stator magnetic bearings

A topology composed of a hollow-shaft rotor on rolling element bearings coupled with internal-stator magnetic bearings mounted on independently supported flexible shafts is considered for the purposes of vibration reduction. Details of a bespoke test rig constructed to assess this topology are prese...
