Abstract

Système destiné à être utilisé avec un résolveur possédant un stator et un rotor et comprenant : un générateur de référence destiné à engendrer des signaux d'excitation de résolveur qui sont adressés au stator du résolveur afin de produire un champ magnétique tournant et destiné à engendrer des données numériques de position de champ tournant indicatives de la position angulaire instantanée du champ magnétique tournant ; et un lecteur de résolveur destiné à engendrer des données numériques de somme de positions indicatives de la somme de la position angulaire instantanée du champ magnétique tournant et de la position angulaire instantanée du rotor du résolveur en réponse au signal induit dans le rotor par le champ magnétique tournant. Système applicable aux systèmes de commande numérique.
