Abstract

Une armature du circuit est constituée par un aimant permanent équipé de deux pièces polaires planes parallèles. D'un côté de l'aimant, une première culasse plane pénètre entre les deux pièces polaires et de l'autre côté, au moins une pièce polaire pénètre entre deux autres culasses planes portées par une même extrémité de noyau. La partie fixe du circuit est constituée par au moins deux tôles superposées avec une liberté limitée de mouvement perpendiculairement aux plans des tôles. Un prolongement non cambré du noyau constitue la première culasse et des prolongements, dont l'un au moins est cambré en baïonnette, de bras de retour du flux constituent les deux autres culasses.
