Abstract

Ce solénoide (10) comprend une armature mobile (11) qui peut se déplacer sur une certaine longueur (13) de course par rapport à un aimant (15). L'armature comporte un noyau (17) constitué d'un matériau magnétique et ayant une première longueur. L'aimant peut etre alimenté électriquement pour fournir un flux magnétique et il présente un trajet de flux ayant une deuxième longueur qui est supérieure à la première longueur ou longueur du noyau. De ce fait, l'aimant exerce sur le noyau une force d'attraction dont l'intensité augmente linéairement sur toute la longueur de la course.
