ABSTRACT:
A passive magnetic bearing suspension system for rotatable or translatable applications. Such bearings systems contain subsystems acting in mutually perpendicular directions to produce an overall system that is statically and dynamically stable. Further, these bearings can be constructed entirely of ring, disk, and/or bar-shaped magnets that are axially magnetized. This reduces the manufacturing difficulties associated with previous systems that required conical magnets and/or radial magnetization.
