In case there is a malfunction of the magnetic bearing in an electrical machine, in which such magnetic bearings drive a rotary shaft in a stator (10), a safety bearing (14,14′) is provided. According to the present invention, the safety bearing (14,14′) exhibits an outer ring (16,16′) that is mounted on the stator (10), inside of which a revolving ring (22,22′,26) is operated. The safety bearing according to the present invention is particularly suited for machines that have a particularly large and heavy shaft. |
