Abstract
An active magnetic bearing assembly includes at least two rotors and two stator assemblies each having two pole faces. The pole faces of the stator assemblies are axially offset from the pole faces of their associated rotors. Thus, axial control of a shaft that is rotationally mounted using the active magnetic bearing assembly is provided by a reluctance centering force.
