Abstract

Commande électromagnétique polarisée, constituée par deux aimants permanents, les pièces polaires entourant partiellement ces derniers, l'armature solidaire de l'arbre d'entraînement et des bobines de commande Les pièces polaires 2 comportent entre l'armature 4 et les aimants permanents 1 des épanouissements 13, radialement en regard des pôles 14 de l'armature, de façon à former des grands entrefers 11 et des petits 12 entre l'armature et les pièces polaires. Les composantes de force dans les petits et les grands entrefers produisent une force résultante, dont la plage de linéarité est nettement supérieure à celle des diverses composantes.
