Abstract:
A rotary frictionless device for supporting an object in rotational movement, comprising:a frame; a rotating assembly mounted for rotary motion on said frame about a rotational axis, including a support to which such an object can be attached to or carried on said assembly, the frame and assembly biasing magnets mounted on said frame and assembly, respectively, for suspending a substantial portion of the weight of the assembly and an object attached to or carried on the assembly, by magnetic attraction between the frame and carriage biasing magnets; and diamagnetic stabilizing means for stabilizing the suspended condition of the rotor on said frame, as the rotor moves rotationally thereon, said stabilizing means including a stabilizing magnet carried on said frame and a diamagnetic plate mounted on said assembly, with at least a portion of the plate confronting and being disposed proximate to the stabilizing magnet, as the rotor assembly moves rotationally, wherein magnetic interaction between said diamagnetic plate and the stabilizing magnetic acts to resist movement of the plate toward the stabilizing magnet.
