Abstract

L'invention est relative à un dispositif de déplacement rapide par effet électromagnétique Une palette associée à un électromoteur impulsionnel permet de prendre le relais de l'impulsion et de disposer d'une force de déplacement d'une durée accrue Une concentration des lignes de courant et/ou du flux magnétique modifie le comportement du dispositif aux différents régimes. Le dispositif peut être appliqué à des disjoncteurs rapides limiteurs.
