Abstract

A.DISPOSITIF DANS LEQUEL LE FREINAGE S'EFFECTUE PAR FRICTION DE SURFACES ENTRE ROTOR ET VENTILATEUR FIXE SUR L'ARBRE DU MOTEUR ELECTRIQUE. B.FREIN CARACTERISE EN CE QUE LE VENTILATEUR FIXE SUR L'ARBRE DU MOTEUR ET DONT UNE FACE CONSTITUE ELLE-MEME LA SURFACE DE FRICTION CONTRE LAQUELLE, EN L'ABSENCE DE COURANT, S'APPLIQUE LE ROTOR POUSSE PAR UN RESSORT, EST CONSTITUE D'UNE SEULE PIECE PAR UNE MATIERE SYNTHETIQUE PARTICULIEREMENT RESISTANTE ET A HAUT COEFFICIENT DE FROTTEMENT, PAR EXEMPLE UNE RESINE THERMODURCISSABLE AVEC CHARGES. C.L'INVENTION TROUVE SON APPLICATION PRINCIPALE DANS LES FREINS POUR MOTEURS ELECTRIQUES.A. DEVICE IN WHICH THE BRAKING IS PERFORMED BY FRICTION OF SURFACES BETWEEN ROTOR AND FAN FIXED ON THE SHAFT OF THE ELECTRIC MOTOR. B. BRAKE CHARACTERIZED IN THAT THE FAN FIXED ON THE MOTOR SHAFT AND OF WHICH ONE SIDE IS ITSELF THE FRICTION SURFACE AGAINST WHICH, IN THE ABSENCE OF CURRENT, APPLIES THE ROTOR PUSHED BY A SPRING, IS CONSTITUTED IN A SINGLE PIECE BY A PARTICULARLY RESISTANT SYNTHETIC MATERIAL WITH A HIGH FRICTION COEFFICIENT, FOR EXAMPLE A THERMOSETABLE RESIN WITH FILLERS. C. THE INVENTION FINDS ITS MAIN APPLICATION IN BRAKES FOR ELECTRIC MOTORS.
