Abstract

La présente invention concerne un dispositif de mouvement linéaire adapté pour l'entraînement moteur ou la génération d'une alimentation électrique. Le dispositif de mouvement linéaire comporte au moins une source de champ magnétique central (1) à polarité de flux axial une fois actionnée, au moins une source de champ magnétique en fente (2) à polarité de flux axiale une fois activée, fixée sur un support (6) et au moins un centre magnétique (3) fait d'un matériau à faible réluctance. La source du champ magnétique en fente (2, 6) est déplaçable dans un sens linéaire parallèle à l'axe longitudinal du centre magnétique (3). Le cœur magnétique (3) est placé entre la source de champ magnétique central (1) et la source du champ magnétique en fente (2). Le cœur magnétique (3) comprend au moins une portion de concentration de champ (4) à surface de coupe constituée d'un matériau à faible réluctance, cette surface étant plus petite que la surface de coupe minimale constituée d'un matériau à faible réluctance du reste du coeur magnétique (3). Les champs magnétiques des sources de champ magnétiques actionnées (1, 2) s'écoulent dans un chemin de moindre réluctance (2, 3, 4, 5) et se concentrent dans la portion de concentration de champ (4) passant à travers. Il en résulte que la force magnétique est exercée sur la source du champ magnétique en fente (2, 6) pour la déplacer dans un sens linéaire parallèle à l'axe longitudinal du centre magnétique (3).
