Abstract
An active radial magnetic bearing assembly for a rotating machine. The active radial magnetic bearing assembly may include a housing comprising a center axis, a stator coupled to the housing, a rotor, a first target, a second target, and a plurality of sensors. At least a portion of the rotor may be configured to rotate about the center axis within the stator. The first target may be a portion of a rotor outer surface and the second target may be coupled to or formed by the rotor. The plurality of sensors may be coupled to the stator and adjacent a stator inner surface. Each sensor of the plurality of sensors may detect at least one of a radial position and an axial position of the rotor via the first target or the second target.
