The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)
In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61377-3 has been prepared by IEC technical committee 9: Electricrailway equipment.The text of this standard is based on the following documents:FDISReport on voting9/693/FDIS9/705/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.Annex A forms an integral part of this standard.This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.The committee has decided that the contents of this publication will remain unchanged until2010.

61377-3  IEC:2002− 7 −RAILWAY APPLICATIONS – ROLLING STOCK −−−−Part 3: Combined testing of alternating current motors,fed by an indirect convertor, and their control system1 Scope and objectThis International Standard applies to the combinations of motor(s), indirect convertors andtheir control system and its object is to specify:−the performance characteristics of electric drives consisting of a convertor, alternatingcurrent motors, and the related control system;−methods of verifying these performance characteristics by tests.Two categories of combined systems can be considered:a)Alternating current motors fed from a convertor without any control between the mechanicaloutput (torque, speed) and the convertor itself (mostly auxiliary motors, for example coolingfan motors). The motor works exactly as if it were fed from a busbar (at variable frequencyand voltage or not).b)Alternating current motor(s) (paralleled or not) with a control between the mechanicaloutput and the inverter.The first category of systems is tested according to IEC 60349-2 and IEC 61287-1.This standard applies to the second category, mainly traction drives.IEC 60349-2 applies to convertor-fed alternating current motors, IEC 61287-1 to powerelectronic convertors; IEC 60571 applies to electronic equipment; this standard applies tothe combination of motor(s), convertors, and their control system. As a consequence,IEC 60349-2 describes the tests to demonstrate the compliance of the motor to itsspecification, IEC 61287-1 does the same for the convertor. It is self-evident that some ofthe tests mentioned in this standard may in general replace the corresponding onesdescribed in the above mentioned standards. An agreement should be reached betweenthe parties to avoid the duplication of tests.A complete combined test is heavy, and often requires high power, which is not alwaysavailable in workshop. An agreement between user and manufacturer may be reached to allowtesting either in the workshop or on the vehicle.At the time of drafting of this standard, only the following combinations of motors and invertershave been used for traction applications, but it may also apply to other combinations which maybe used in the future:−asynchronous motors fed by voltage stiff (voltage source) inverter;−asynchronous motors fed by current stiff (current source) inverter;−synchronous motors fed by current stiff (current source) inverter.SIST EN 61377-3:2003

Thesecurves are defined as the “specified characteristics”. They shall be plotted to the designedoperating limits of each variable. They shall generally be drawn for the a.c. or d.c. supplyvoltage of the traction system at its specified nominal value. They may also be drawn for thelower and higher voltage of the supply of the traction system if agreed between user andmanufacturer. These characteristics shall be drawn for a reference temperature of the windingsof the motor of 150 °C, and the temperature of the parts of the convertor expected by thesupplier.SIST EN 61377-3:2003

In which case, the gear ratio, wheel diameter and transmissionlosses shall be stated. If conventional values are used for the latter, they shall be inaccordance with figure B.1 of IEC 60349-2.The specified characteristics shall be submitted to the user before the order for the combinedsystem is placed, unless otherwise specified.The values of the supply voltage of the traction system shall be specified by the user. Theyshould preferably be the standard values according to IEC 60850.5.2 Declared characteristicsCharacteristic curves obtained from the results of type tests carried out in accordance with 7.5.5.3 Combined system characteristicsThe specified and declared characteristics of the combined system shown as a function ofspeed, over the whole application range are:a)External characteristics such as the mechanical torque, the values of the input: voltage,current and power of the combined system.b)Internal characteristics such as current and voltage of the intermediate d.c. link, if any, theroot-mean-square value of the output current of the inverter, the root-mean-square of thefundamental components of the output current and voltage of the inverter, the slip ofasynchronous motors, the excitation current for synchronous motors.c)Internal values such as switching transients, which are the point-to-point and point to earthpeak voltages, temperatures, etc.NOTE
Internal switching transients are of use to check the dielectric test voltage of the constituents.If the efficiency is an important parameter, it shall be requested, and this characteristicshall also be shown. Efficiency is particularly important for combined systems used onthermal/electric rolling stock, or battery-fed vehicles.The efficiency characteristic of the combined system shall take into account the relevantcomponents, such as the motor, the convertor, the cables, cooling fans and the pumps.The measurement of efficiency shall include excitation losses in the case of synchronousmachines.Only external characteristics, and the maximum internal repetitive switching transients aremandatory. Other internal characteristics and values may be measured, but the results shallnot influence the acceptance of the combined system.Figures 3 to 6 show examples of the most common mandatory curves.5.4 Exchange of information and responsibilityIEC 60349-2 and IEC 61287-1 point out the need for the exchange of information between themotor supplier and the convertor supplier, to ensure that the combined system will meet therequirements of the above mentioned standards, the documents recording this exchange ofinformation being an integral part of the specification of the motor and of the convertor.SIST EN 61377-3:2003



61377-3  IEC:2002− 17 −Definition 3.3 defines the manufacturer as the organization which has the technicalresponsibility for the supply of the combined system. As a consequence, it is responsible forthe technical specification of the constituents of the combined system in order to meet therequirements of this standard.6 Test categories6.1 GeneralThere are three categories of tests:−type tests;−investigation tests;−routine tests.This standard is not directly concerned with routine tests. Each component of the system isroutine tested according to its relevant standard.6.2 Type testsType tests are intended to prove the ratings, characteristics and performances of a newcombined system. They shall be carried out on one combined system of every new design.If modifications of the design or manufacturing process of the constituents are decided afterthe combined system has been type-tested, the influence of these modifications on theperformances of the combined system shall be evaluated. An agreement may then be reachedbetween user and manufacturer not to carry out the type test again, or to carry out only someof the tests.Subject to agreement between user and manufacturer, a type test is not required if themanufacturer produces a full type test report carried out on a combined system of similardesign, with the same cooling conditions, and similar power.6.3 Investigation testsThe object of investigation tests is to obtain additional information either on the convertor whenit feeds the motor, or on the motor when it is fed by the convertor, or on the controller of thecombined system. They shall be carried out only if a previous agreement has been reachedbetween user and manufacturer. The results of these tests shall not influence the acceptanceof the system unless so agreed between user and manufacturer.7 Tests7.1 GeneralCombined testing gives the opportunity to run the constituents of the combined system with theactual parameters as in service. The torque of the motor, the d.c. link voltage (or current, incase of current stiff convertor), if any, the output current and voltage of the convertor, etc., arethose produced in service.The manufacturer shall provide the user before the commencement of testing with a testspecification outlining the tests to be undertaken from this standard to meet the contractrequirements. Following the completion of testing, the manufacturer shall supply the user witha full test report.SIST EN 61377-3:2003

The power cables should preferably bethose which will be used on the vehicle, but equivalent power cables may be used. Themanufacturer shall give all information about these cables and their arrangement if requested.NOTE
It is not necessary to have exactly the same arrangement of the cables as they will be in the vehicle,provided the local worst conditions are simulated on the test bed. As an example, if the highest temperature risecan reasonably be expected in a portion of 2 m of the
