LARGE DIAMETER RADIAL MAGNETIC BEARING

摘要

IN THE CANADIAN PATENT /A TRADEMARK OFFICE PATENT APPLICATION entitled: A large diameter radial magnetic bearing. in the names of: H. Habsrmann and M. Brunet assigned to: SOCIETE EUROPEENNE DE PROPULSION The rotor of the radial bearing comprises a central shaft and a stack of ferromagnetic laminations constituted by a set of very thin individual laminations each of which extends over a limited angular sector around the periphery of the central shaft, said laminations being disposed in parallel planes so as to constitute a succession of flat split rings extending perpendicularly to the rotor axis. The individual laminations in any given plane are angularly offset relative to the individual laminations of the adjacent planes in such a manner as to provide a stack of laminations which is staggered. A bearing in accordance with the invention is suitable for supporting large diameter shafts which rotate at high speeds.
