Abstract

Un actionneur électromagnétique (6) possède une caractéristique de déplacement de force sensiblement linéaire. Cette caractéristique est obtenue au moyen de deux bobines (16, 17) qui produisent des champs magnétiques ayant une interaction avec des éléments d'induit respectifs (19, 20). La caractéristique de déplacement de force des élément d'induits (19, 20), individuellement, est quadratique. Cependant, dans l'actionneur (6), ils sont conçus pour fonctionner selon un mode push-pull provoquant une caractéristique de déplacement de force linéarisée de l'induit (10) dans son ensemble. Des aimants de polarisation (32, 33) sont associés aux bobines respectives (16, 17) pour optimiser la linéarisation de la caractéristique de déplacement de force de l'induit.
