A stator housing surrounds the portion of a rotor having a magnetic flux carrying member extending around the rotor within the stator housing. A plurality of electromagnets are supported by the stator around the periphery of the rotor oppositely of the magnetic flux carrying member. Each of the electromagnets includes a stacked arrangement of laminations having an E-shaped cross-sectional configuration. Each lamination includes a pole tip in close proximity to the surface of the magnetic flux carrying member to form an air gap. Magnetizing coils extend around the legs of the E-shaped laminations. When electrical current is supplied to the coils, magnetic forces are exerted upon the magnetic flux carrying member enabling the rotor to be positioned in a levitated state within the stator housing.
