Title (EN) MAGNETIC BEARING ASSEMBLY
(FR) ENSEMBLE PALIER MAGNÉTIQUE
(DE) MAGNETLAGERANORDNUNG
Abstract:
(EN) The invention relates to a magnetic bearing assembly (1) for mounting a shaft of a rotary machine, comprising a bearing (3), in particular a radial bearing, in the form of an electromagnetic bearing, the bearing (3) comprising at least a rotor (2) and a stator (5). The stator (5) has electrical windings (6) for generating a magnetic field, and the stator (5) consists of multiple annular elements made of ferromagnetic material. At least one annular element (7) is made of a ferromagnetic material with a crystalline structure, and at least one second annular element (8) is made of a ferromagnetic material with an amorphous structure.
(FR) L'invention concerne un ensemble palier magnétique (1) pour le support sur palier d'un arbre d'une machine rotative, comprenant un palier (3) réalisé sous forme de palier électromagnétique, en particulier un palier radial, le palier (3) comprenant au moins un rotor (2) et un stator (5). Le stator (5) présente des enroulements électriques (6) pour générer un champ magnétique et le stator (5) se compose de plusieurs éléments annulaires en matériau ferromagnétique. Au moins un élément annulaire (7) est constitué dans ce cas d'un matériau ferromagnétique à structure cristalline et au moins un second élément annulaire (8) est constitué d'un matériau ferromagnétique à structure amorphe.
(DE) Die Erfindung betrifft eine Magnetlageranordnung (1) zur Lagerung einer Welle einer Rotationsmaschine, umfassend ein als elektromagnetisches Lager ausgebildetes Lager (3), insbesondere ein Radiallager, wobei das Lager (3) wenigstens einen Rotor (2) und einen Stator (5) umfasst. Der Stator (5) weist elektrische Wicklungen (6) zur Erzeugung eines Magnetfeldes auf und der Stator (5) besteht aus mehreren ringförmigen Elementen aus ferromagnetischem Material. Wenigstens ein ringförmiges Element (7) besteht dabei aus einem ferromagnetischen Material mit kristalliner Struktur und wenigstens ein zweites ringförmiges Element (8) besteht aus einem ferromagnetischen Material mit amorpher Struktur.
