Abstract:
A magnetic bearing (20) has: a rotor (22) to be supported for rotation about an axis (502); and a stator (24) extending from a first end (30) to a second end (32). The stator has: a circumferential outer winding (50); a circumferential inner winding (52); a radial spacing (54) between the inner winding and the outer winding; a plurality of laminate teeth (84A, 84B, 86A, 86B); and a plurality of radial windings (34A, 34B, 36A, 36B) respectively encircling a respective associated tooth of the plurality of teeth. A plurality of magnetic flux paths are respectively associated with the plurality of radial windings and pass: radially through the associated winding; axially through the radial spacing; radially from the radial spacing to the rotor; and axially along the rotor.
