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 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 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 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 60034-8 has been prepared by IEC technical committee 2:
Rotating machinery.
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.

The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be

INTRODUCTION
The revision of this part of IEC 60034 provides worldwide uniformity in the electrical
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 standardized terminal markings.

SIST EN 60034-8:2007
– 12 – 60034-8 © IEC:2007
6.1.3 Alphanumeric marking notation
The terminal marking comprises upper-case Latin characters and Arabic numerals. The
characters shall be arranged without spaces.
Each winding, winding phase or auxiliary circuit shall be assigned a letter symbol(s) in
accordance with Clause 4.
To prevent confusion with the numerals 1 and 0, the letters “I” and “O” shall not be used.
6.1.4 Duplicate winding terminals
Several leads of a machine can have the same marking only if each of them is capable of
completely fulfilling the same electrical function, so that either one of them can be used for
the connection. See Figure 9.
6.1.5 Shared terminals
When several leads or conductors are provided to share the current, the terminal markings
shall be identified by an additional numerical suffix separated by a hyphen. See Figure 10.
Some multi-speed motors having two or more independent windings may produce circulating
currents in the de-energized winding. In this case, the terminal markings for the open delta
connection shall be identified by an additional numerical suffix separated by a hyphen. See
Figure A.15.
6.1.6 Omissions
Numerical suffixes and/or prefixes may be omitted if there is no risk of confusion. See
Figure 2.
