Električni rotacijski stroji - 12. del: Zagonske lastnosti enohitrostnih trifaznih motorjev s kratkostično kletko (IEC 60034-12:2016)
Ta del standarda IEC 60034 določa parametre za osem modelov zagonskih lastnosti enohitrostnih trifaznih motorjev s kratkostično kletko (50 Hz ali 60 Hz) v skladu s standardom IEC 60034-1, ki:
– imajo nazivno napetost do 1000 V;
– so namenjeni za neposredni ali zvezda-trikot zagon;
– so ocenjeni na podlagi tipa delovanja S1;
– so zasnovani z vsemi varnostnimi stopnjami in zaščito pred eksplozijo.
Ta dokument se uporablja tudi za motorje z dvojno napetostjo pod pogojem, da je raven tokovne zasičenosti enaka za obe napetosti.
Vrednosti navora, navidezne moči in toka, podane v tem dokumentu, so mejne vrednosti (tj. najmanjše ali največje vrednosti brez odstopanj).
OPOMBA 1 Ni pričakovati, da bodo vsi proizvajalci izdelovali stroje za vse osem modelov. Izbira katerega koli posebnega oblikovanja v skladu s tem dokumentom bo predmet dogovora med proizvajalcem in kupcem.
OPOMBA 2: Za določene aplikacije so morda potrebni modeli, ki niso navedeni med temi osmimi.
OPOMBA 3: Opozoriti je treba, da lahko vrednosti, navedene v katalogih proizvajalcev, vključujejo odstopanja v skladu s standardom IEC 60034-1.
OPOMBA 4: Navedene vrednosti za navidezno moč zaprtega rotorja temeljijo na RMS-simetričnih ustaljenih tokovih zaprtega rotorja; pri zagonu motorja mora biti prisoten polkrožen asimetrični pretočni največji tok med 1,8- in 2,8-kratno vrednostjo ustaljenega toka zaprtega rotorja. Trenutni čas najvišje in najnižje vrednosti je funkcija zasnove motorja in preklopnega kota.

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 60034-12 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.
