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.

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

INTRODUCTION
This part of IEC 61800 has been developed to allow evaluation of power losses of CDMs
(complete drive modules) and PDSs (power drive systems).
The requirements for measuring energy efficiency of motors with non-sinusoidal supply are
under the responsibility of IEC/TC 2 and will be published under the IEC 60034 series.
IEC SC 22G includes the standardization task force for dealing with this topic. It has close
collaboration with several other technical committees (for example, IEC TC 2, IEC SC 121A).
IEC SC 22G maintains responsibility for all relevant aspects in the field of energy efficiency
and ecodesign requirements for power electronics, switchgear, control gear and power drive
systems and their industrial applications.
The core requirements of energy efficiency standardization are illustrated in Figure 1. The
work has been agreed to provide the reasonable target as a best compromise.

IEC 61800 (all parts) does not deal with mechanical engineering components.
NOTE Geared motors (motors with directly adapted gearboxes) are treated like power drive systems (converter
plus motor). See IEC 60034-30-1 for classification of the losses of a geared motor. The efficiency classes of
gearboxes as individual components are under consideration.
IEC 61800-9-2 is a subpart of the IEC 61800 series, which has the following structure:
– Part 1: General requirements – Rating specifications for low voltage adjustable speed DC
power drive systems
– Part 2: General requirements – Rating specifications for low voltage adjustable speed AC
power drive systems
– Part 3: EMC requirements and specific test methods
– Part 4: General requirements – Rating specifications for AC power drive systems above
1 000 V AC and not exceeding 35 kV
– Part 5: Safety requirements
– Part 6: Guide for determination of types of load duty and corresponding current ratings
– Part 7: Generic interface and use of profiles for power drive systems
– Part 8: Specification of voltage on the power interface
– Part 9: Ecodesign for power drive systems, motor starters, power electronics and their
driven applications
Each part is further subdivided into several subparts, published either as International
Standards or as Technical Specifications or Technical Reports, some of which have already
been published. Other will be published with the part number followed by a dash and a
second number identifying the subdivision (example: IEC 61800-9-2).
It considers basic requirements from the EN 50598-2 CENELEC standard published on
2014-12-19 and considers also the following key points in cooperation with relevant technical
committees.
It has been developed in close collaboration with other technical committees (IEC TC 2, IEC
SC 121A) and with a customer’s stakeholder committee CEN/TC 197 in order to provide a
comprehensive standard for energy efficiency and ecodesign requirements.
Key points:
• Requirements for energy-efficient design of electric drive systems in accordance with the
driven load
• Requirements and IE-classification of complete drive modules (CDM)
• Requirements and IES-classification of power drive systems (PDS)
• Determination of PDS losses and requirements for the link to the driven equipment for the
determination of energy efficiency classification/evaluation of the extended product
• Requirements for an environmentally conscious system design and environmental
declaration of a motor system
