Abstract

LA PRESENTE INVENTION A POUR OBJET UN DISPOSITIF D'ENTRAINEMENT D'UN VENTILATEUR DE REFROIDISSEMENT DE MOTEUR REDUISANT LES BRUITS. CE DISPOSITIF COMPORTE UN VENTILATEUR DE REFROIDISSEMENT 15 QUI PEUT TOURNER SUR L'ARBRE 7 DU MOTEUR, PLUSIEURS PAIRES D'AIMANTS 16A, 16B MONTES SUR LE ROTOR OU LE VENTILATEUR ET UN DISQUE TOURNANT 17 REALISE EN UN METAL NON FERREUX MAIS CONDUCTEUR DE L'ELECTRICITE, FIXE SUR LE VENTILATEUR OU LE ROTOR, DE MANIERE A FORMER UN ACCOUPLEMENT PAR COURANTS DE FOUCAULT DONT LE GLISSEMENT AUGMENTE AVEC LA VITESSE DE ROTATION DU ROTOR. APPLICATION A LA REDUCTION DU BRUIT PROVOQUE PAR UN MOTEUR ELECTRIQUE.THE SUBJECT OF THE PRESENT INVENTION IS A DEVICE FOR DRIVING AN ENGINE COOLING FAN REDUCING NOISE. THIS DEVICE INCLUDES A COOLING FAN 15 WHICH CAN ROTATE ON THE MOTOR SHAFT 7, SEVERAL PAIRS OF MAGNETS 16A, 16B MOUNTED ON THE ROTOR OR THE FAN AND A TURNING DISC 17 MADE OF A NON-FERROUS METAL BUT CONDUCTS THE L ' ELECTRICITY, FIXED ON THE FAN OR THE ROTOR, SO AS TO FORM A COUPLING BY EDDY CURRENTS WHOSE SLIDING INCREASES WITH THE ROTOR SPEED. APPLICATION TO THE REDUCTION OF NOISE CAUSED BY AN ELECTRIC MOTOR.
