Abstract

Il s'agit d'un actionneur magnétique comportant une partie magnétique mobile (4), une partie magnétique fixe (5) et des moyens (6) pour déclencher le déplacement de la partie magnétique mobile (4) par rapport à la partie magnétique fixe (5). Il comporte au moins deux supports (1, 2) amagnétiques, placés dans des plans différents, délimitant entre eux un espace (3), la partie magnétique fixe (5) étant solidaire d'au moins un des supports (1, 2). Les supports (1, 2) présentent chacun une zone de butée (10, 20) pour la partie magnétique mobile (4), la zone de butée (10, 20) étant distincte de la partie magnétique fixe (5). La partie magnétique mobile (4) est en lévitation dans l'espace (3) entre les deux supports (1,2) grâce à un guidage magnétique dû à la partie magnétique fixe (5) lorsqu'elle n'est pas en butée contre la zone de butée (10, 20) de l'un des supports (1, 2). La partie magnétique mobile (4) est susceptible de prendre plusieurs positions magnétiques stables, dans chacune de ces positions, elles est en butée contre un support (1,2).
