Abstract

Ce codeur optique comprend une partie rotor (1604) avec une extrémité interne disposée de façon à créer une pression qui maintient le chemin de roulement interne d'un palier de l'arbre du moteur sous pression axiale contre un décrochement de l'arbre, des paliers qui maintiennent le stator (1607) du codeur axialement et radialement fixe par rapport au rotor du codeur, et un ressort plat (1623) qui permet un écart entre le stator du codeur et un blindage arrière (1612) du moteur, sans entraîner de mouvements de rotation notables entre le stator du codeur et le blindage arrière du moteur. Le rotor du codeur porte un disque codeur (1603) à son autre extrémité, un dispositif irradiant (1615) situé dans le stator du codeur fournissant un faisceau lumineux qui traverse axialement le disque codeur et qui est détecté par des capteurs lumineux (1616), cet agencement permettant de concevoir le codeur avec une faible longueur axiale.
