ROTATING ELECTRICAL MACHINES –

Part 19: Specific test methods for d.c. machines
on conventional and rectifier-fed supplies

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 60034-19 has been prepared by IEC technical committee 2:
Rotating machinery.
This second edition cancels and replaces the first edition published in 1995. It constitutes a
technical revision. The main technical changes with regard to the previous edition are as
follows:
a) The description of the procedure for black band testing has been detailed and clarified.
b) Procedures for measurement of the magnetization curves under no-load and load
conditions have been added.

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 Directives, Part 2.
NOTE A table of cross-references of all IEC TC 2 publications can be found on 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 the IEC web site 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.

ROTATING ELECTRICAL MACHINES –

Part 19: Specific test methods for d.c. machines
on conventional and rectifier-fed supplies

1 Scope
This part of IEC 60034 applies to d.c. machines rated 1 kW and above operating on rectifier-
fed power supplies, d.c. buses or other d.c. sources.
Standardized methods are provided for determining characteristic quantities for conventional
and rectifier-fed d.c. machines.
Excluded are d.c machines for specific applications.
These methods supplement the requirements in IEC 60034-1 and IEC 60034-2-1.
NOTE It is not intended that this standard should be interpreted as requiring the carrying out of any or all of the
tests described therein on any given machine.

4 Determination of current and voltage specific quantities (rectifier-fed)
4.1 General
This test serves to determine the variation of the terminal voltage and armature current for
rectifier-fed d.c. machines at rated conditions.
4.2 Current ripple
The armature current ripple is best measured with an oscilloscope incorporating capability for
reading both d.c. and a.c. values. An alternative method is to use a peak-to-peak reading

voltmeter, reading the voltage drop across a non-inductive resistor in series with the armature
circuit.
4.3 Voltage ripple
The voltage ripple may be measured using an oscilloscope, a suitable oscillograph or an
