Abstract

L'invention concerne un gyroscope. Il comprend un rotor entraîné par un arbre de moteur par l'intermédiaire d'un anneau intermédiaire couplé au moteur et au rotor par des barres de torsion à 90 degrés les unes des autres, et des moteurs de précession pour appliquer au rotor des couples de précession dans des plans contenant l'axe de rotation de l'arbre moteur. Les moteurs de précession sont des électroaimants fixes exerçant une force d'attraction sur le rotor. Il est prévu un système d'alimentation en courant des électroaimants, réagissant à une commande par un signal électrique de commande, ce système ayant une réponse telle que le couple d'attraction exercé par un couple d'électroaimants diamétralement opposés soit une fonction linéaire d'un paramètre du signal de commande du courant appliqué aux électroaimants. Application à un gyroscope à suspension élastique destiné à tourner à grande vitesse.
