Abstract
A stator assembly for a magnetic bearing includes a core member formed of a ferromagnetic material and including an outer annular portion and a plurality of projections extending radially inwardly from the outer annular portion and spaced circumferentially about a centerline. A plurality of bobbins are formed of an electrically insulative material and include a first shell half disposed against a first axial end of a separate one of the projections and a second shell half disposed against a second axial end of the projection. The second shell half is coupled with the first shell half such that the one projection is enclosed within a cavity defined between the two shell halves. A plurality of windings each include at least one wire wound about a bobbin and electrically coupleable with a source of electric power such that each winding and the projection encircled by the winding provide a magnetic pole.
