Abstract
An axial magnetic thrust bearing stator includes a plurality of laminated cores. Each of the cores is magnetically conductive, situated in a common plane, and symmetrically situated about a center of rotation. A plurality of electrically conductive coils are provided with each coil situated at least partially in a respective one of the cores.
