Foreword
This document (EN 50598-1:2014) has been prepared by CLC/TC 22X "Power electronics".
The following dates are fixed:

(dop) 2015-11-17
• latest date by which this document has
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2017-11-17
standards conflicting with this
document have to be withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association.
EN 50598, Ecodesign for power drive systems, motor starters, power electronics & their driven
applications, will consist of the following parts:
- Part 1: General requirements for setting energy efficiency standards for power driven equipment
using the extended product approach (EPA), and semi analytical model (SAM);
- Part 2: Energy efficiency indicators for power drive systems and motor starters;
- Part 3: Quantitative ecodesign approach through life cycle assessment including product category
rules and the content of environmental declarations.
The CLC/TC 22X/WG 06 is the enabled task force for dealing with the Mandate M/476 from European
Commission for the standardization in the field of variable speed drives and/or power drive system
products.
It has been set a close collaboration with several other technical committees (i.e. CLC/TC 2;
CLC/TC 17B) in order to provide a comprehensive standard for energy efficiency aspects and
ecodesign requirements together with a pilot stakeholder committee CEN/TC 197 from the customers
side.
Key points:
- Requirements on the content of semi analytical models for motor system driven equipment;
- Requirements how to use them in the extended product approach.
The content could be of interest for the following technical committees CLC/TC 59X, CLC/TC 111X,
CEN/TC 44, CEN/TC 113, CEN/TC 121, CEN/TC 123, CEN/TC 142, CEN/TC 143, CEN/TC 156,
CEN/TC 228, CEN/TC 232 and CEN/TC 299.
It is the intention of the working group that this document, once finalized as European standard series,
will be further processed to an international consensus in IEC and ISO.
Introduction
The Technical Committee CLC/TC 22X has circulated at 2010-03-31 the document
CLC/TC 22X/Sec0100/DC document including the mandate M/476 from European Commission for
standardization in the field of variable speed drives and/or power drive system products.
As the PDS contains converter driven motors, the requirements for measuring of the energy efficiency
of motors with non-sinusoidal supply is under the responsibility of CLC/TC2 covering the requirement
from Mandate M/470.
The document is based on the CENELEC technical board document referenced BT137/DG8058/INF
also reproducing this EC-mandate.
The CLC/TC 22X/WG 06 as being the standardization task force for dealing with this Mandate has
close collaboration with several other technical committees (i.e. CLC/TC 2; CLC/TC 17B).
Therefore CLC/TC 22X committee has been enabled responsible to clarify 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 sometimes controversial requirements are illustrated in Figure 1. The work has been agreed to
provide the reasonable target as a best compromise.

standardization
EN 50598 is developed under the CENELEC projects number 24602 to 24604 for compliance with
requirements from the horizontal mandate M/495.
Its three parts are together directly related to the mandates M/470 and M/476.
For the other mandates listed in Table 1, this standard could be applied if the future product standards
developed will make reference to it.

1 Scope
This European Standard provides a general methodology to energy efficiency standardization for any
extended product including a motor system by using the methodological guidance of the extended
product approach (EPA).
It enables product committees for driven equipment with included motor systems to interact with the
relative power losses of the included motor system (e.g. PDS) in order to determine the system energy
efficiency aspects for the extended product by calculation.
This should be based on specified calculation models for speed/load profiles, the duty profiles and
relative power losses of appropriate torque versus speed operating points.
This part of the EN 50598 series specifies the methodology of determination of losses of the extended
product including a motor system and its sub-parts.
This framework is explained by an example for pumps.
This part of the standard does not specify requirements for environmental impact declarations.
