26、EC 2016 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ROTATING ELECTRICAL MACHINES Part 12: Starting performance of single-speed three-phase cage induction motors FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national e
27、lectrotechnical 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 Spec
28、ifications, 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. Interna
29、tional, 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 form
30、al 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 fo
31、r 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
32、) 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 shal
33、l 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 certif
34、ication 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 inju
35、ry, 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 c
36、ited 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 identif
37、ying any or all such patent rights. International Standard IEC 60034-12 has been prepared by IEC technical committee 2: Rotating machinery. This third edition cancels and replaces the second edition, published in 2002, and its amendment 1, published in 2007. It constitutes a technical revision. 4 IE
38、C 60034-12:2016 IEC 2016 The main technical changes with regard to the previous edition are as follows: Clause or subclause Change 1 Part of note 3 moved to the regular text 3 Definition of locked rotor current and of rated voltage added 5 New design letter E for extended efficiency motors, explanat
39、ion of all design letters, and description of new designs NE, NEY, HE, and HEY 6.2 and 9.2 Limits for locked rotor apparent power for E(Ex)e motors replaced by a reference to IEC 60079-7 Formula added to calculate locked rotor current from apparent power 7 and 10 Definition of new limits for locked
40、rotor apparent power for extended efficiency motors (new table 3) Tables Tables 1 and 4 to 7 extended down to P N= 120 W Name of type of protection updated according to IEC 60079-7 Ed. 5 The text of this standard is based on the following documents: CDV Report on voting 2/1789/CDV 2/1821A/RVC Full i
41、nformation 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 Directives, Part 2. A list of all parts of the IEC 60034 series, published under the general title Rotating e
42、lectrical machines, can be found on the IEC website. NOTE A table of cross-references of all IEC TC 2 publications can be found in the IEC TC 2 dashboard on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on th
43、e IEC website under “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. IEC 60034-12:2016 IEC 2016 5 ROTATING ELECTRICAL MACHINES Part 12: Starting performance of single-spee
44、d three-phase cage induction motors 1 Scope This part of IEC 60034 specifies the parameters for eight designs of starting performance of single-speed three-phase 50 Hz or 60 Hz cage induction motors in accordance with IEC 60034-1 that: have a rated voltage up to 1 000 V; are intended for direct-on-l
45、ine or star-delta starting; are rated on the basis of duty type S1; are constructed to any degree of protection and explosion protection. This document also applies to dual voltage motors provided that the flux saturation level is the same for both voltages. The values of torque, apparent power and
46、current given in this document are limiting values (that is, minimum or maximum without tolerance). NOTE 1 It is not expected that all manufacturers will produce machines for all eight designs. The selection of any specific design in accordance with this document will be a matter of agreement betwee
47、n the manufacturer and the purchaser. NOTE 2 Designs other than the eight specified may be necessary for particular applications. NOTE 3 It should be noted that values given in manufacturers catalogues may include tolerances in accordance with IEC 60034-1. NOTE 4 The values tabled for locked rotor a
48、pparent power are based on r.m.s. symmetrical steady state locked rotor currents; at motor switch on there will be a one-half cycle asymmetrical instantaneous peak current which may range from 1,8 to 2,8 times the steady state locked rotor value. The current peak and decay time are a function of the
49、 motor design and switching angle. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
