Abstract

Il s'agit d'un actionneur magnétique possédant un circuit magnétique fermé comportant une partie magnétique mobile (22) et une partie magnétique fixe (21) reliées magnétiquement entre elles et définissant au moins un entrefer (26). Ce circuit magnétique est apte à guider un flux magnétique permettant de déplacer la partie magnétique mobile (22) vers la partie magnétique fixe (21). La partie magnétique mobile (22) est flexible et comporte au moins une zone (31) ayant une section variable transversalement au flux magnétique.
