Abstract

L'invention concerne un dispositif de palier magnétique (1) pour le logement sans contact d'un corps mobile (3) tel qu'un arbre, comportant une partie de palier fixe (2) pourvue d'un système d'aimant électromagnétique (11) pouvant recevoir en fonctionnement, un courant de commande dépendant d'écarts du corps (3) par rapport à la position de consigne. Au moins un composant électrique ou électronique (50-55) tel qu'un composant d'électronique de commande, un composant d'électronique de puissance et/ou un composant d'alimentation électrique, est logé dans au moins un espace libre (60) entre des composants système du dispositif de palier magnétique (1), notamment dans des éléments de retour (5, 6).
