ABSTRACT:
Magnetic support structure for a rotatable machinery part is described which comprises a stationary support structure, an annular stator comprising an array of a plurality of electromagnets or one or more electrically conductive or superconductive elements supported by the support structure about an axis, rim structure attached to the periphery of the rotatable part for rotation therewith about the axis radially inwardly of and proximate to the electromagnets, the rim structure including electrically conductive non-ferromagnetic material for magnetic interaction with the stator, and a source of power for selectively energizing the stator.
