  • Electrical machine with magnetic bearing and safety bearing
    Patent number: 7952247
    Abstract: 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.
