Passive magnetic support and damping system
First Claim
1. A passive magnetic support and damping system comprising:
- a) a rotor, said rotor having at least one permanently magnetized element attached to said rotor;
b) a stator, said stator including at least one second permanently magnetized element, whereby said rotor and said stator being arranged in a relationship whereby the permanently magnetized element of the rotor and the permanently magnetized element of the stator are separated by a gap;
c) a support for said stator; and
d) a means for supporting the at least one second permanently magnetized element so as to dampen vibrations in said at least one second permanently magnetized element and, consequently, dampen vibrations in said at least one permanently magnetized element attached to said rotor.

Abstract
A type of passive magnetic bearing that provides for both positive radial stiffness and significant levels of passive radial damping. Axial damping and axial forces can also be generated with minor modifications to the basic configuration. The bearing is comprised of a series of magnet, damping, and rigid non-magnetic elements essentially defining a laminated or composite structure. The damping material is directly mounted between the magnets and a rigid material, resulting in constrained layer damping. The range of motion of these floating, or soft mounted, magnets may also be restricted to generate higher stiffness in response to large vibrations.

19. A passive magnetic support and damping system comprising:
-
a) a rotor, said rotor being comprised of a first array of permanently magnetized elements arranged in a side-by-side relationship;
