Claim:
1. A machine, comprising: a rotating shaft configured to be driven by a motor; at least two magnetic radial bearings positionable axially from the motor and configured to magnetically levitate the rotating shaft, each of said at least two magnetic radial bearings comprising at least three stator magnet groups, each of said at least three stator magnet groups operatively coupled to a single respective controller and comprising at least three stator magnets that are substantially uniformly distributed around a longitudinal axis of said rotating shaft, no pair of said at least three stator magnets being separated by 180 degrees measured about said longitudinal axis, and each of said at least three stator magnet groups being operatively configured via electronic control by the single respective controller to fully support and position said rotating shaft utilizing a horizontal force and a vertical force and independently of each other stator magnet group of said at least three stator magnet groups.
