Rotating electrical machines - Part 1: Rating and performance

IEC 60034-1:2010 is applicable to all rotating electrical machines except those covered by other IEC standards, for example, IEC 60349. Machines within the scope of this standard may also be subject to superseding, modifying or additional requirements in other publications, for example, IEC 60079 and IEC 60092. The changes with respect to the previous edition are as follows: - clarification of water coolant temperature, - recognition of IE code, - clarification of the term "tolerances".

Drehende elektrische Maschinen - Teil 1: Bemessung und Betriebsverhalten

Machines électriques tournantes - Partie 1: Caractéristiques assignées et caractéristiques de fonctionnement

La CEI 60034-1:2010 est applicable à toutes les machines électriques tournantes à l'exception de celles qui font l'objet d'autres normes de la CEI, par exemple la CEI 60349. Les machines comprises dans le domaine d'application de la présente norme peuvent également être soumises à des exigences nouvelles, modifiées ou complémentaires figurant dans d'autres publications - par exemple, la série CEI 60079 et la CEI 60092. Les modification par rapport à l'édition précédente sont les suivantes: - clarification portant sur la température de l'eau de refroidissement, - reconnaissance du code IE, - clarification du terme " tolérances ".

Električni rotacijski stroji - 1. del: Nazivni podatki in preskus lastnosti (IEC 60034-1:2010, spremenjen) (vsebuje popravek AC:2010)

Ta del IEC 60034 velja za vse električne rotacijske stroje, razen tiste, ki jih zajemajo drugi IEC standardi, na primer IEC 60349 [10]1. Stroji znotraj področja uporabe tega standarda so lahko tudi predmet zahtev za zamenjavo in spreminjanje ter dodatnih zahtev v drugih objavah, na primer v IEC 60079 [8] in IEC 60092 [9].

ROTATING ELECTRICAL MACHINES –
Part 1: Rating and performance
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 60034-1 has been prepared by IEC technical committee 2:

Rotating machinery.

This twelfth edition cancels and replaces the eleventh edition published in 2004. It constitutes

a technical revision.

Major changes were not introduced in this edition. The corrections, clarifications and

improvements include:
