This part of EN 50598 specifies the Energy Efficiency indicators for power drive systems, motor starters, power electronics (e.g. Complete Drive Modules, CDM) used in motor driven applications in the power range of 0,12 kW up to 1000 kW.
This part of EN 50598 specifies the methodology for determination of losses of the complete motor system, the power drive system (PDS) and the CDM. It defines IE and IES-classes, their limit values and provides test procedures for the classification and the overall losses of the motor system.
Furthermore, this part of EN 50598 proposes a methodology for characterization of the best energy efficiency solution to be implemented, depending on the motor driven system architecture, the speed/load profile and the duty profiles of the application.
The structure of EN 50598 contains the following:
• the losses of a standardized reference PDS (RPDS) and the mathematical model of their calculation are given;
• requirements for determining the losses of a real PDS are given, and be classified in comparison to the RPDS;
• requirements for the type testing and the content of user documentation;
• some illustrations of losses in an overall system as an example are given in Annexes;
• information about system and drive topologies are given in Annexes.
Specific data on losses and IE/IES-classes are given for low voltage (100 V up and equal to 1 000 V) single axis AC/AC power drive systems with three phase induction motors. Geared motors shall be treated as standard motors.
This part of EN 50598 does not specify the methodology for eco-design for environmental impact. This is defined in Part 3 of EN 50598.

160 Foreword
161 This document [prEN 50598-2:2013] has been prepared by CLC/TC 22X "Power electronics".
162 This document is currently submitted to the Enquiry.
163 This document has been prepared under a mandate given to CENELEC by the European Commission
164 and the European Free Trade Association, and supports essential requirements of EU Directive(s).
165 The TC22X Working Group 6 as being the standardization Task Force for dealing with the Mandate
166 M/476 from European Commission for standardization in the field of variable speed drives and/or
167 Power Drive System products has been set a close collaboration with several other technical
168 committees (i.e. CLC/TC2; CLC/TC17B; CEN TC 197) in order to provide a comprehensive standard
169 for energy efficiency and eco design requirements.
170 Key points:
171 • Clear requirements how to achieve an energy efficient driven equipment using a power drive
172 system
173 • Requirements and limits for IE-classes for power electronic converters
174 • Requirements and limits for IES-classes for Power Drive Systems (PDS)
175 • Loss determination of the PDS and requirements for the link to the driven equipment in order
176 to determine the energy efficiency classification/evaluation of the extended product
177 • Requirements how to achieve the environmental conscious design and environmental
178 declaration of PDS
179 It is the intention of the working group that this document, once finalised as European standard, will be
180 further processed to an international consensus in IEC according to the UAP procedure agreement
181 between CENELEC and IEC.

182 Introduction
183 The CENELEC TC22X Technical Committee has circulated on last 2010-03-31 for a short period of
184 time the CLC/TC22X/Sec0100/DC document including the Mandate M/476 from European
185 Commission for standardization in the field of variable speed drives and/or Power Drive System
186 products.
187 As the PDS contains converter driven motors, the additional requirements for measuring of the energy
188 efficiency of those motors with non-sinusoidal supply and the labelling for the whole PDS are also
189 included. This covers the requirements coming from the Mandate M/470.
190 The document is based on the CENELEC Technical board document referenced BT137/DG8058/INF
191 also reproducing this EC-Mandate.
192 The TC22X Working Group 6 as being the standardization Task Force for dealing with this Mandate
193 has anticipated that a close collaboration with several other technical committees (i.e. CLC/TC2;
194 CLC/TC17B) should be set.
195 Therefore CLC TC22X Committee has taken its responsibility this field and has started a
196 standardization work to clarify all aspects in field of Energy efficiency and Eco-design requirements for
197 Power electronics, Switchgear, Control gear, and Power drive systems and their industrial
198 applications.
199 The sometimes controversial requirements in the field of these tasks are illustrated in Figure 1. The
200 work has been agreed to provide the reasonable target as a best compromise in this field.

204 EN 50598 is developed under the CENELEC projects number 24602 to 24604 for compliance with
205 requirements from the horizontal mandate M/495. EN 50598 “Ecodesign for power drive systems,
206 motor starters, power electronics & their driven applications” will consist of the following parts:
207 Part 1: General requirements for setting energy efficiency standards for power driven equipment
208 using the extended product approach (EPA), and semi analytic model (SAM);
209 Part 2: Energy efficiency indicators for power drive systems and motor starters;
210 Part 3: Quantitative eco design approach through life cycle assessment including product category
211 rules and the content of environmental declarations.

212 The parts together will provide the appropriate set of standards also covering the individual mandates
213 M/470, M/476, M/498, M/500 already in reference within the mandate M/495 and the upcoming
214 mandates for standardization of other power driven applications.
