General requirements for setting energy efficiency standards
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.

1 INTRODUCTION
2 IEC SC 22G includes the standardization task force for dealing with energy efficiency of motor
3 systems. It has close collaboration with several other technical committees (for example,
4 IEC TC 2, IEC SC 121A).
5 IEC SC 22G maintains responsibility for all relevant aspects in the field of energy efficiency and
6 ecodesign requirements for power electronics, switchgear, control gear and power drive
7 systems and their industrial applications.
8 The core requirements of energy efficiency standardization are illustrated in Figure I.1. The
9 work has been agreed to provide the reasonable target as a best compromise.

13 IEC 61800 (all parts) do not deal with mechanical engineering components.
14 NOTE Geared motors (motors with directly adapted gearboxes) are treated like power drive systems (converter plus
15 motor). See IEC 60034-30-1 for classification of the losses of a geared motor. The efficiency classes of gearboxes
16 as individual components are under consideration.
17 IEC 61800-9-1 is a subpart of the IEC 61800 series, which has the following structure:
18 – Part 1: General requirements – Rating specifications for low voltage adjustable speed D.C.
19 power drive systems
20 – Part 2: General requirements – Rating specifications for low voltage adjustable speed A.C.
21 power drive systems
22 – Part 3: EMC requirements and specific test methods

24 – Part 6: Guide for determination of types of load duty and corresponding current ratings
25 – Part 7: Generic interface and use of profiles for power drive systems
26 – Part 8: Specification of voltage on the power interface
27 – Part 9: Ecodesign for motor systems
28 Each part is further subdivided into several subparts, published either as International
29 Standards or as Technical Specifications or Technical Reports, some of which have already

30 been published. Others will be published with the part number followed by a dash and a second
31 number identifying the subdivision (for example, IEC 61800-9-2).
32 This subpart of IEC 61800-9 is an International Standard for characterizing the energy efficiency
33 of motor systems when supplied by a motor starter or by a variable voltage/frequency converter.
34 The goal of this part of IEC 61800-9 is to establish a clear and simple system for the comparison
35 of the energy performance of motor systems that can help manufacturers to improve their
36 products, to give users the necessary transparency and information and to provide a robust
37 reference base for regulators and minimum energy performance standards.
38 The IEC 61800-9 series (Ecodesign for motor systems) consist of the following subparts:

50 1 Scope
51 This part of IEC 61800 specifies the general methodology to energy efficiency standardization
52 for any extended product by using the guidance of the extended product approach (EPA).
53 This document is a Group Energy Efficiency Publication as defined in IEC Guide 119 with the
54 energy efficiency function to establish a clear and simple system methodology for the
55 comparison of the energy performance of motor systems to help product and system
56 improvement.
57 It enables product committees for driven equipment connected to motor systems (so called
58 extended products) to interface with the relative power losses of the connected motor system
59 (e.g. power drive system) in order to calculate the system energy efficiency for the whole
60 application.
61 This is based on specified calculation models for speed/load profiles, the duty profiles and
62 relative power losses of appropriate torque versus speed operating points.
63 This document is applicable to motor systems operated by a motor starter or by a converter
64 (power drive system).
65 This document does not specify requirements for environmental impact declarations.
66 Power Drive Systems designed to drive DC motors are not included in the Scope of this
67 Standard.

218 4.1 General
219 This document specifies a methodology to determine the energy efficiency indicator of an
220 application, based on the concept of semi analytic models (SAM). The methodology shall be
221 referred to as an extended product approach (EPA).
222 The responsibilities and tasks of the different stakeholders creating or using these extended
223 products standards, as well as the data flows in-between, are specified.
224 a) Specific information about the equipment shall be considered:
225 – The torque versus speed profile of the driven load as specified by the load manufacturer
226 or other pertinent entity (e.g. regulatory authority, other specified organization).
227 – The losses of the Motor System or its constituents (motor, CDM or motor starter) at
228 reference part-load operating points. These shall be provided by the different
229 manufacturers as specified in IEC 61800-9-2.
230 b) Information about the application shall be considered:
231 – The duty profile of the driven equipment. Pertinent entities can for example define typical
232 applications of their extended products, each associated with a typical duty profile.
233 c) The extended product approach permits the determination of an energy efficiency indicator
234 (losses, efficiency, energy consumption, etc.):

235 – Other pertinent entity(ies) (e.g. regulatory authority, other specified organization) shall
236 define how to combine the losses of the motor system and the losses of the load, to
237 obtain an overall energy efficiency indicator for the extended product within the defined
238 application.
239 – The IEC TR 62837:2013 suggests the definition and use of key performance indicators
240 (KPIs) for energy efficiency through automation systems that are in accordance with the
