Abstract

MOTEUR-FREIN ELECTRIQUE COMPRENANT UN PLATEAU MOBILE 11 POUVANT ETRE SERRE ENTRE DES GARNITURES 27 PAR UN PLATEAU FIXE 18 QUAND CE DERNIER N'EST PAS ATTIRE PAR UN ELECTRO-AIMANT 14. QUAND LE MOTEUR EST ALIMENTE, L'ELECTRO-AIMANT 14 EST EXCITE ET ATTIRE LE DISQUE 18, CE QUI DESSERRE LE FREIN. LA FACE 28 DU PLATEAU 18 VENANT AU CONTACT DE L'ARMATURE 15 PRESENTE UNE RUGOSITE PARTICULIERE QUI EVITE LES COLLAGES INTEMPESTIFS QUAND ON COUPE LE COURANT. APPLICATION AU FREINAGE INSTANTANE DES MOTEURS ELECTRIQUES.ELECTRIC MOTOR-BRAKE INCLUDING A MOBILE PLATE 11 THAT CAN BE CLAMPED BETWEEN GASKETS 27 BY A FIXED PLATE 18 WHEN THE LATTER IS NOT ATTRACTED BY AN ELECTRO-MAGNET 14. WHEN THE MOTOR IS POWERED, THE ELECTRO-MAGNET 14 IS ON AND ATTRACTS DISC 18, RELEASING THE BRAKE. THE FACE 28 OF THE PLATE 18 COMING IN CONTACT WITH THE REINFORCEMENT 15 PRESENTS A PARTICULAR ROUGHNESS WHICH PREVENTS INTEMPESTIVE BONDING WHEN THE CURRENT IS CUT. APPLICATION TO INSTANT BRAKING OF ELECTRIC MOTORS.
