Abstract
An electromagnetic bearing includes a canning arrangement (30, FIG. 2) for separating stator coils 33 from a suspension gap 21 containing gas at high pressure. The canning arrangement comprises a bridging member 38.sub.1 . . . in each cell slot 31.sub.1, 32.sub.2 . . . supported on notches 37 cut from the edges of bounding pole pieces 31.sub.1, 32.sub.2 . . . , the surface of which bridging member facing the rotor comprises a support face set radially outwardly of the pole faces. A thin, deformable can member 40 is supported on the pole faces and deforms outwardly in response to pressure difference between suspension gap and coil slot into contact with the bridging members and locates the can member and bridging members. The can and bridging members may be formed of stainless steel and deformation may be plastic.
