Abstract
Axial magnetic bearings are described suitable for use where high loads and high rotational speeds are found together. The bearings comprises an assembly where, for thrusts along the shaft in one direction, the shaft has, in relation thereto, two axially spaced, and radially extending, thrust accepting faces, a generally channel-shaped, annular electromagnet surrounding the shaft, with a radially extending face of each pole of the electromagnet adjacent to an individually associated thrust face.
