Abstract
A magnetic bearing system for support of a body, such as an energy storage flywheel, for rotational about a substantially vertical axis of rotation through its center of mass. The bearing system includes a rotating portion and a stationary portion on each axial side of the center of mass. Two or more concentric axially magnetized ring poles on an axial surface of the rotating body are constructed of multiple individual permanent magnet pieces, arranged in rigs inside a containment cup in the end face of the rotor with radially adjacent rings having alternating magnetic polarities. On the stationary portion, two or more concentric axially magnetized pole rings of permanent magnet material cooperate with the rotating ring magnets to produce both an axial attractive force and a radial centering force.
