31、60034-8 IEC:2007 5 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ROTATING ELECTRICAL MACHINES Part 8: Terminal markings and direction of rotation FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical com
32、mittees (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, Technic
33、al 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, governmenta
34、l 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 agre
35、ements 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
36、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 promot
37、e 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 indicat
38、ed in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to
39、 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
40、 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)
41、 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 60034-8 has been prepared by IEC technical committee 2: Rotating m
42、achinery. This third edition of IEC 60034-8 cancels and replaces the second edition published in 2002 and constitutes a technical revision. The main change with respect to the previous edition is listed below: changed terminal markings for d.c. machines in Clause A.4. 6 60034-8 IEC:2007 The text of
43、this standard is based on the following documents: FDIS Report on voting 2/1434/FDIS 2/1451/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directi
44、ves, Part 2. A list of all the parts of the IEC 60034 series, under the general title Rotating electrical machines, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site u
45、nder “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60034-8 IEC:2007 7 INTRODUCTION The revision of this part of IEC 60034 provides worldwide uniformity in the electrica
46、l connections for rotating electrical machines and applies the recommendations of the basic safety publication IEC 60445 in specifying marking requirements. These standardized connections will then permit the safe interchange of electric machines with their control and protective devices using stand
47、ardized terminal markings. 8 60034-8 IEC:2007 ROTATING ELECTRICAL MACHINES Part 8: Terminal markings and direction of rotation 1 Scope This part of IEC 60034 applies to a.c. and d.c. machines and specifies a) rules for the identification of winding connection points; b) marking of winding terminals;
48、 c) direction of rotation; d) relationship between terminal markings and direction of rotation; e) terminal marking of auxiliary devices; f) connection diagrams of machines for common applications. Turbine-type synchronous machines are excluded from this standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60034-1, Rotating electrical m
