Carbon brushes, brush holders, commutators and slip-rings - Definitions and nomenclature

IEC 60276:2018 applies to carbon brushes for electrical machinery. This edition applies only to carbon brushes for commutators and slip-rings in rotating machines. Terms and definitions are relative to the brush construction (references 100’s to 500’s and parts of 900’s) and to the markings when operating on a rotating machine (references 600’s to 800’s). This new edition includes the following significant technical changes with respect to the previous edition:  
Some nomenclature has been deleted or added, whereas remaining definitions have been detailed and clarified, to reflect the technical evolution since 1987.
Additional definitions have been included to address the request for reviewing this standard, in particular nomenclature of commutator/slip-rings markings, brush markings and commutation sparks codes.

Balais de charbon, porte-balais, collecteurs et bagues - Définitions et nomenclature

L'IEC 60276:2018 s'applique aux balais de charbon pour machines électriques. Pour le moment, il n'est applicable qu'à des balais de charbon montés sur collecteurs et bagues dans les machines tournantes. Les termes et définitions se rapportent à la construction des balais (numéros de référence 100 et suivants à 500 et suivants et parties 900 et suivantes) ainsi qu'aux états de surface lorsqu'ils sont utilisés sur une machine tournante (numéros de référence 600 et suivants à 800 et suivants). Cette nouvelle édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:  
Certaines nomenclatures ont été supprimées ou ajoutées, alors que les définitions restantes ont été détaillées et clarifiées, pour refléter l’évolution technique depuis 1987.
Des définitions supplémentaires ont été incluses pour répondre à la demande de révision de la présente norme, en particulier la nomenclature des états de surface des collecteurs/bagues, les états de surface des balais et les cotations des étincelles pour la commutation.

Ogljikove ščetke, držalo ščetk, komutatorji in drsni obroči - Definicije in nomenklatura (IEC 60276:2018)

Ta dokument se uporablja za ogljikove ščetke za električne stroje. Trenutno se uporablja samo za ogljikove ščetke za komutatorje in drsne obroče v rotacijskih strojih. Izrazi in definicije se navezujejo na zgradbo ščetke (sklicevanja na 100–500 in dele 900) ter oznake pri obratovanju v rotacijskem stroju (sklicevanja na 600–800). Z razširitvijo so lahko izrazi in definicije primerni za vse vrste drsnih električnih kontaktov v električnih strojih.

CARBON BRUSHES, BRUSH HOLDERS, COMMUTATORS
AND SLIP-RINGS – DEFINITIONS AND NOMENCLATURE

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60276 has been prepared by IEC technical committee 2: Rotating
machinery.
This second edition cancels and replaces the first edition, issued in 1968 and its
Amendment 1, issued in 1987. It constitutes a t
