Abstract

Un systeme de mesure de rotation comprend un codeur magnétique annulaire (16) tournant portant une série d'élèments de codage (23) agencés circonférentiellement sur le codeur selon un motif périodique, caractérisé par le fait qu'il comprend un ensemble capteur primaire (38) comportant au moins un capteur magnétique primaire (38) disposé en regard des éléments de codage pour la détection de la position angulaire du codeur avec une résolution angulaire discrète d'une fraction de tour égale ou inférieure à une période du codeur et un compteur electronique du nombre de fractions de tour effectuées, et un ensemble capteur secondaire comprenant des capteurs magnétiques secondaires 24a à 24d, 25a à 25d disposés en regard des éléments de codage pour déterminer une position absolue du codeur entre deux positions décaléees d'au moins une fraction de tour.
