Abstract

Dispositif de mesure de position absolue de résolveur pour commande numérique d'une machine ayant une pluralité d'organes mobiles respectivement connectés à un résolveur. Dispositif dans lequel un compteur en temps réel 41 délivre un mot de données qui est cycliquement redondant, une première et une seconde mémoire 42, 43 adressées par le compteur 41 délivrent respectivement une séquence de mots de données représentant une onde sinusoïdale, lesquelles sont en quadrature, un premier et un second convertisseur N/A 46, 49 sensibles respectivement à la première et à la seconde mémoire 42, 43 délivrent une onde sinusoïdale et une onde cosinusoïdale à un premier et un second enroulement de stator de chaque résolveur RES 1-4, l'onde de rotor correspondante est appliquée à un détecteur de phase 51-54, les sorties de ces detecteurs 51-54 sont multiplexées et le signal multiplexé est utilisé pour stocker le comptage en cours du compteur 41, ces comptages représentant les angles de phase des résolveurs RES 1-4.
