16、034-2-3 IEC:2013 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ROTATING ELECTRICAL MACHINES Part 2-3: Specific test methods for determining losses and efficiency of converter-fed AC induction motors FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for stand
17、ardization 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 Int
18、ernational 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 participa
19、te 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
20、 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
21、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 m
22、isinterpretation 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 na
23、tional 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 service
24、s 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 Nation
25、al 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
26、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
27、not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obt
28、ained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to
29、 review within three years of publication to decide whether they can be transformed into International Standards.

35、3 5 INTRODUCTION The objective of this technical specification is to define test methods for determining the additional harmonic motor losses of converter-fed induction motors. These losses appear in addition to the losses on nominally sinusoidal power supply as determined by the methods of IEC 6003
36、4-2-1. Results determined according to this specification are intended to allow for comparison of the harmonic losses of different AC induction motors when fed by converters. In power-drive systems (PDS), the motor and the frequency converter are often manufactured by different suppliers. While moto
37、rs of the same design are produced in large quantities, they may be operated from the grid or from frequency converters of many different types, supplied by many different manufacturers. The individual converter properties (switching frequency, DC link voltage level, etc.) may influence the system e
38、fficiency as well. It is impractical to determine the additional harmonic motor losses for every combination of motor, frequency converter, connection cable, output filter and parameter settings. Accepting that it is extremely difficult to specify motor efficiency for converter operation, this speci
39、fication describes a limited number of approaches, depending on the voltage level and the rating of the machine under test. The procedures described in this specification result in a single number, the harmonic loss ratio rHL, which is the ratio of the additional harmonic motor losses and the motor
40、losses measured using a nominally sinusoidal voltage power supply. The losses determined according to this specification are not intended to represent the losses in the final application. They provide, however, an objective basis for comparing different motor designs with respect to suitability for
41、converter operation. The methods in this technical specification apply to induction motors used with variable frequency drives. However, the application to other AC motors or DC motors and converters, is not excluded. The methods are mainly intended for motors fed by voltage source converters. In ge
42、neral, when fed from a converter, the motor losses are higher than during operation on a nominally sinusoidal system. The additional harmonic losses depend on the spectrum of the impressed converter output quantity (either current or voltage) which is influenced by its circuitry and control method.
43、For further information see IEC/TS 60034-25. This technical specification is aimed at evaluating the additional harmonic motor losses resulting from non-sinusoidal power supply and consequently the efficiency of the converter-fed motor. It is not the purpose of this technical specification to define
44、 test procedures either for power drive systems or for frequency converters alone. This technical specification is applicable to motors rated for 50 Hz or 60 Hz fundamental frequency. However, for other rated motor frequencies the test procedure may be applied provided a suitable power source is ava
45、ilable, e.g. a 4-pole motor used at 3 000 rpm can be tested with 100 Hz and actual voltage rating. Low-voltage motors Experience has shown that the additional harmonic motor losses generally increase with load. The methods in this technical specification are based on supplies from converters with pu
46、lse width modulation (PWM) and constant pulse pattern. This is generally the case for voltage source converters except for over-modulation. Such voltage source converters have by far the largest market share in the low-voltage industrial drive market. With respect to these types of converters and th
47、e growing need for verification of compliance with national energy efficiency regulations, this technical specification introduces a so-called test converter for testing low voltage motors.

The motor efficiency is to be determined at rated load for 50 Hz or 60 Hz. Defining 50 Hz or 60 Hz as test conditions has the advantage of providing a direct comparison of motor efficiency for grid and converter operation. The above outlined test converter concept is a new approach to weigh the converter impact on an electric
