Abstract

DISPOSITIF PERMETTANT D'ACTIONNER SANS A-COUPS, A VITESSE VARIABLE, ET AVEC UN RENDEMENT OPTIMISE, UN MOTEUR SYNCHRONE, ASYNCHRONE, OU PAS A PAS, A PARTIR D'UNE SOURCE A COURANT CONTINU. IL COMPREND UN CIRCUIT MAGNETIQUE EQUIPE D'UN OU PLUSIEURS BOBINAGES RELIES A UNE SOURCE D'ENERGIE ELECTRIQUE PAR DES MOYENS DE COMMUTATION. UN CAPTEUR D'INDUCTION MAGNETIQUE DELIVRE UN SIGNAL QUI, COMPARE A DIVERS SEUILS, GENERE DES SIGNAUX BINAIRES PERMETTANT D'ACTIONNER LES MOYENS DE COMMUTATION D'UNE PART, ET DE DELIVRER DES INFORMATIONS SUR CERTAINES PHASES PARTICULIERES DU PROCESSUS D'AUTRE PART. L'INVENTION PEUT ETRE UTILISEE POUR REALISER DES ASSERVISSEMENTS DE PRECISION EN POSITION OU EN VITESSE, DESTINES A LA MACHINE OUTIL, OU POUR ACTIONNER DES MOTEURS DESTINES AU TRANSPORT.
