A magnetic bearing for rapidly rotating machines (1), in particular, for turbo compressors, drag vacuum pumps, or similar, includes two bearings (3, 4), each with a stator magnetic-ring set (5, 7) and a rotor magnetic-ring set (6, 8). Movement of the rotor is damped by magnetic-ring sets (5, 6; 7, 8) arranged concentrically to each other. The stator magnetic-ring set (5 or 7) is arranged externally and the rotor magnetic-ring set (6 or 8) is arranged internally. Non-magnetic elements with good electrical conducting properties (32, 54, 55) are connected to the outer circumference surfaces of at least one part of the magnetic ring of each of the stator-side magnetic-ring sets (5, 7). |
