Abstract

L'invention concerne une suspension magnétique pour arbre à vitesse de rotation élevée qui comprend un dispositif (1) de stabilisation de la position de l'arbre (2) par rapport à un boîtier (3) dans la direction axiale, et des dispositifs (4, 5) servant à stabiliser la position de l'arbre (2) par rapport à un boîtier (3) dans les directions radiales, dont l'un au moins comporte au moins une unité (23 ou 24) comprenant un système de magnétisation monté sur le boîtier (3) dans le même axe que des circuits magnétiques (9, 10) montés sur le boîtier (3) avec possibilité d'interaction avec les pôles du système de magnétisation. L'arbre (2) porte un circuit magnétique (11) décalé par rapport auxdits circuits magnétiques. Les surfaces des circuits magnétiques (9, 10, 11) qui se font face et qui sont situées perpendiculairement à l'axe de l'arbre (2) sont munies de protubérances concentriques (12, 13) disposées en paires les unes en face des autres et de même largeur. Chaque circuit magnétique (9, 10) monté sur le boîtier (3) est muni de fentes radiales (20) qui le divisent en sections égales (19), les protubérances concentriques (12, 13) étant placées sur la surface de chaque section (19).
