Abstract
LA PRESENTE INVENTION SE RAPPORTE A UN SYSTEME D'ENTRAINEMENT D'UNE PLATINE. SELON L'INVENTION, IL COMPREND UN BOITIER 16, OU EST MONTEE ROTATIVE UNE PLATINE 12 AVEC UN MOYEN 24 POUR SA ROTATION COMPORTANT UN STATOR 28 ET UN ROTOR 30; LE STATOR SE COMPOSE D'UN NOYAU DEFINISSANT UN ENTREFER 32 POUR RECEVOIR LE ROTOR ET D'UN ENROULEMENT DE CHAMP 34 POUR ETABLIR UN FLUX MAGNETIQUE ALTERNATIF A UNE FREQUENCE DONNEE DANS LE NOYAU; UN MOYEN ELASTIQUE 38 RELIANT LE ROTOR A LA PLATINE; UN MOYEN 26 DE REGLAGE DE LA VITESSE DE LA PLATINE COMPORTANT UN MOYEN 52, 54 RELIE AU NOYAU POUR DETOURNER UNE PARTIE DU FLUX MAGNETIQUE VERS DEUX PIECES POLAIRES 56, 58 ET UN ANNEAU 50 MONTE SUR LA PLATINE A PROXIMITE DES PIECES POLAIRES, AYANT UN CERTAIN NOMBRE DE POLES MAGNETISES EN PERMANENCE DE POLARITE ALTERNEE; LA RELATION ENTRE LA FREQUENCE DONNEE ET LE NOMBRE DE POLES MAGNETISES EN PERMANENCE ETANT TELLE QUE LE MOYEN DE REGLAGE DE VITESSE S'OPPOSE A DES ECARTS DE LA VITESSE DE ROTATION DE LA PLATINE PAR RAPPORT A UNE VALEUR SOUHAITEE. L'INVENTION S'APPLIQUE NOTAMMENT AUX VIDEODISQUES.
