Dimensions, marking and testing of carbon brushes and dimensions of brush-holders for electrical machinery
IEC 60136:2024 applies primarily to brushes and brush-holders for cylindrical commutators and slip rings for electrical rotating machines. Some clauses of this document may cover other configurations, such as flat commutators or plain disks. It defines the dimensions of brushes and their components, together with their tolerances: - dimensions of brush block (t, a, r), - angles α and β, - chamfer, - flexibles (shunts), - standard terminals. It also covers the conventional designation of principal dimensions, the marking of brushes and the testing methods for the qualification of brushes after their manufacturing (except the brush grade material, covered by IEC 60413). This third edition cancels and replaces the second edition published in 1986 and Amendment 1:1995. This edition constitutes a technical revision. Please refer to the Foreword of the document for a comprehensive listing of the changes with respect to the previous edition.
Abmessungen, Kennzeichnung und Prüfung von Kohlebürsten und Abmessungen von Bürstenhaltern für elektrische Maschinen
Dimensions, marquages et essais des balais et dimensions des porte-balais pour machines électriques
IEC 60136:2024 s'applique principalement aux balais et aux porte-balais montés sur collecteurs cylindriques et bagues des machines électriques tournantes. Certains articles du présent document peuvent couvrir d'autres configurations, comme les collecteurs plats ou les disques lisses. Il définit les dimensions des balais et de leurs composants, ainsi que leurs tolérances: - dimensions du bloc de balai (t, a, r); - angles α et β; - chanfrein; - câbles (shunts); - cosses normalisées. Il couvre également la désignation conventionnelle des dimensions principales, le marquage des balais et les méthodes d'essai pour la qualification des balais après leur fabrication (à l'exception du matériau de la nuance des balais, couvert par l'IEC 60413). Cette troisième édition annule et remplace la deuxième édition parue en 1986 et l'Amendement 1:1995. Cette édition constitue une révision technique. Veuillez vous référer à l'avant-propos du document pour une liste complète des modifications par rapport à l'édition précédente.
