Electric traction - Rotating electrical machines for rail and road vehicles - Part 2: Electronic converter-fed alternating current motors (IEC 60349-2:2010)

This part of IEC 60349 applies to converter-fed alternating current motors forming part of the equipment of electrically propelled rail and road vehicles. The object of this part is to enable the performance of a motor to be confirmed by tests and to provide a basis for assessment of its suitability for a specified duty and for comparison with other motors. Where further testing is to be undertaken in accordance with IEC 61377-1 and IEC 61377- 3, it may be preferable, to avoid duplication, that some type and investigation tests be carried out on the combined test bed. Particular attention is drawn to the need for collaboration between the designers of the motor and its associated converter as detailed in 5.1.

Traction électrique - Machines électriques tournantes des véhicules ferroviaires et routiers - Partie 2: Moteurs à courant alternatif alimentés par convertisseurs électroniques (CEI 60349-2:2010)

La CEI 60349-2:2010 s'applique aux moteurs à courant alternatif alimentés par convertisseur qui font partie de l'équipement des véhicules ferroviaires et routiers à propulsion électrique. L'objet de cette partie est de permettre de vérifier, par des essais, les performances d'un moteur, de servir de base à l'estimation de son aptitude à assurer un service donné, et de fournir une base de comparaison avec d'autres moteurs. Les principales modifications techniques par rapport à l'édition précédente sont les suivantes:  - les limites valables pour les moteurs de traction sont maintenant directement spécifiées dans cette norme;  - les méthodes décrites dans les normes ISO pertinentes sont à présent autorisées.

Železniške naprave - Rotacijski električni stroji za železniška in cestna vozila - 2. del: Elektronsko napajani izmenični motorji (IEC 60349-2:2010)

Ta del IEC60349 velja za napajalne izmenične motorje, ki tvorijo del opreme električno gnanih železniških in cestnih vozil. Cilj tega dela standarda je omogočiti, da preskusi potrdijo zmogljivost motorjev ter da se zagotovi osnova za ocenjevanje njegove primernosti za določeno funkcijo in za primerjavo z drugimi motorji. Kjer se bodo izvedla nadaljnja preskušanja v skladu z IEC 61377-1 in IEC 61377-3, bo morda bolje, da se nekateri tipski in preiskovalni preskusi izvedejo v kombinirani preskusni napravi v izogib ponavljanju. Posebna pozornost je namenjena potrebi po sodelovanju med načrtovalci motorja in njegovega pridruženega pretvornika, kot je podrobno opisano v točki 5.1.

motors are now directly stated in this standard.
– In addition to the existing method for measuring and calculating the sound power level, the methods
described in EN ISO 3741, EN ISO 3743 (series), EN ISO 3744, ISO 3745, EN ISO 9614 (series) are
also allowed. However the maximum sound power levels and the correction for pure tones remain
unchanged in C.7 and C.8.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:

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 60349-2 has been prepared by IEC technical committee 9: Electrical
equipment and systems for railways.
This third edition cancels and replaces the second edition published in 2002. It constitutes a
technical revision.
The main technical changes with regard to the previous edition are as follows:
– As the limits of vibration velocities have been changed in IEC 60034-14, the limits valid for
traction motors are now directly stated in this standard.
– In addition to the existing method for measuring and calculating the sound power level, the
methods described in ISO 3741, ISO 3743, ISO 3744, ISO 3745, ISO 9614 are also
allowed. However the maximum sound power levels and the correction for pure tones
remain unchanged in Clauses C.7 and C.8.

Part 2: Electronic converter-fed alternating current motors



1 Scope and object
This part of IEC 60349 applies to converter-fed alternating current motors forming part of the
equipment of electrically propelled rail and road vehicles.
The object of this part is to enable the performance of a motor to be confirmed by tests and to
provide a basis for assessment of its suitability for a specified duty and for comparison with
other motors.
Where further testing is to be undertaken in accordance with IEC 61377-1 and IEC 61377-
3, it may be preferable, to avoid duplication, that some type and investigation tests be
carried out on the combined test bed.
Particular attention is drawn to the need for collaboration between the designers of the motor
and its associated converter as detailed in 5.1.
NOTE 1 This part also applies to motors installed on trailers hauled by powered vehicles.
NOTE 2 The basic requirements of this part may be applied to motors for special purpose vehicles such as mine
locomotives but this part does not cover flameproof or other special features that may be required.
NOTE 3 It is not intended that this part should apply to motors on small road vehicles, such as battery-fed delivery
vehicles, factory trucks, etc. This part also does not apply to minor machines such as windscreen wiper motors, etc.
that may be used on all types of vehicles.
NOTE 4 Industrial type motors complying with IEC 60034 may be suitable for some auxiliary drives, providing that
it is demonstrated that operation on a converter supply will meet the requirements of the particular application.
The rating of traction motors fed in parallel by a common converter has to take into account the
effect on load-sharing of differences of wheel diameter and of motor characteristics as well as
weight transfer when operating at high coefficients of adhesion. The user is to be informed of
the maximum permissible difference in wheel diameter for the particular application.
The electrical input to motors covered by this part comes from an electronic converter.
NOTE 5 At the time of drafting, only the following combinations of motors and converters had been used for
traction applications, but it may also apply to other combinations which may be used in the future:
– asynchronous motors fed by voltage source converters;
– asynchronous motors fed by current source converters;
– synchronous motors fed by current source converters.
The motors covered by this part are classified as follows:
a) Traction motors – Motors for propelling rail or road vehicles.
b) Auxiliary motors not covered by IEC 60034 – Motors for driving compressors, fans, auxiliary
generators or other auxiliary machines.

For the purposes of this document, the terms and definitions given in IEC 60050-131,
IEC 60050-151, IEC 60050-411 and IEC 60050-811, as well as the following, apply.
3.1
rating of a motor
combination of simultaneous values of electrical and mechanical quantities, with their duration
and sequence, assigned to the motor by the manufacturer
3.2
rated value
numerical value of any quantity included in a rating
3.3
continuous rating
mechanical output that the motor can deliver on the test bed for an unlimited time under the
conditions specified in 8.1 without exceeding the limits of temperature rise given in Table 2, all
other appropriate requirements in this part also being satisfied
NOTE Several continuous ratings may be specified.

---------------------- Page: 13 ----------------------

SIST EN 60349-2:2011
– 8 – 60349-2 © IEC:2010
3.4
short-time rating (for example, one hour)
mechanical output that the motor can deliver on the test bed for the stated time without
exceeding the limits of temperature rise given in Table 2, the test being carried out as specified
in 8.1 starting with the motor cold, all other appropriate requirements in this part being also
satisfied
3.5
short-time overload rating
mechanical output that the motor can deliver on the test bed for the stated time without
exceeding the limits of temperature rise given in Table 3, the test being started and carried out
as specified in 8.1.6
NOTE Short-time overload ratings are of value in determining the suitability of motors for duties which involve
relatively long periods of operation below the continuous rating followed by a period above it. These are most likely
to occur in locomotive applications. They are not relevant to the repeated short load cycles of rapid transit and
similar duties, and should not be specified for such applications.
3.6
intermittent duty rating
duty cycle in which the motor may be operated without the temperature rises exceeding the
limits given in Table 2 at any point
3.7
equivalent rating
continuous rating with constant values of voltage, current and speed that, as far as
temperature rise is concerned, is equivalent to the intermittent duty cycle which the motor has
to withstand in service
NOTE This rating should be agreed between user and manufacturer.
3.8
guaranteed rating
rating assigned by the manufacturer for test purposes
3.9
guaranteed rating of a traction motor
normally the continuous rating but in special cases the user and manufacturer may agree that it
be a short-time or intermittent rating
3.10
guaranteed rating of an auxiliary motor
continuous rating unless otherwise specified
3.11
rated voltage
root-mean-square value of the fundamental component of the line-to-line voltage applied to a
motor when it is operating at a guaranteed rating.
NOTE For motors fed directly or indirectly from a contact system, it is normally the highest voltage (excluding
transients) which can be applied to the motor when it is drawing the rated current, with the contact system at its
nominal voltage as defined in Annex D.
3.12
rated speed
speed at a guaranteed rating
