Abstract

L'INVENTION CONCERNE LE DOMAINE DES POTENTIOMETRES INDUCTIFS, DELIVRANT UNE TENSION CONTINUE DE SORTIE LINEAIREMENT VARIABLE EN FONCTION DE L'ANGLE DE ROTATION D'UN AXE. LE POTENTIOMETRE EST CONSTITUE PAR UN SYNCHRO-RESOLVER M ET DEUX CIRCUITS ASSOCIES, UN CIRCUIT D'ALIMENTATION EN TENSION ALTERNATIVE D'UN ENROULEMENT DU STATOR, COMPORTANT UN OSCILLATEUR A AMPLITUDE COMMANDEE 7 PAR LA TENSION D'ALIMENTATION V, ET UN CIRCUIT DE SORTIE, CONNECTE AU ROTOR R, ET COMPORTANT UN ETAGE DEMODULATEUR 9. LA LINEARISATION DE LA TENSION V EN FONCTION DE LA POSITION ANGULAIRE DE L'AXE EST ASSUREE PAR UNE DERIVATION DU CIRCUIT EN 20, COMPRENANT UN AMPLIFICATEUR 12 DE GAIN PROCHE DE0,5, ATTAQUANT UN AUTRE ENROULEMENT DU STATOR. LES APPLICATIONS SONT NOTAMMENT DU DOMAINE DES CAPTEURS ANGULAIRES POUR LES SERVO-MECANISMES.
