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.

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.

4 Requirements for the development of energy efficiency standards for
extended products
4.1 General
This document specifies a methodology to determine the energy efficiency index of an application,
based on the concept of semi analytical models (SAM). The methodology shall be referred to as the
extended product approach (EPA).
This document also specifies the responsibilities and tasks of the different stakeholders creating or
using these extended products standards, as well as the data flows in-between.
a) Specific information about the equipment shall be considered:
1) The torque versus speed profile of the driven equipment as specified by the manufacturer of
the driven equipment or the extended product technical committee.
2) The losses of the motor system or its constituents (Motor, CDM or starter) at reference part-
load operating points. These shall be provided by the different manufacturers as specified in
EN 50598-2.
3) The duty profile of the driven equipment. The extended product standards committee can for
example define typical applications of their extended products, each associated with a typical
duty profile
b) The extended product approach shall be used to determine an energy efficiency indicator (losses,
efficiency, energy consumption…):
1) EN 50598-2 specifies the methods for the determination of losses of the motor system using
measurement and/or calculations.
2) extended product standardization committees shall define how to combine the losses of the
motor system and the losses of the load to obtain an overall energy efficiency aspects related
indicator for the extended product within the defined application.
The interactions between the different stakeholders of the extended product approach are shown in
Figure C.1.
4.2 Responsibility of the driven equipment technical committee
Based on the general principles described in this standard it shall be the responsibility of the driven
equipment technical committee to standardize the methodology to calculate the EEI of the extended
product based on a semi analytical model of the driven equipment.
The product committee shall specify and standardize:
 one or more torque versus speed profiles (load profiles) as described in 5.2 considering typical
loads;
 one or more duty profiles as described in 5.3 considering the typical extended product service
conditions;
 an appropriate method for determining the losses at intermediate operating points based on the
data from the motor, CDM and PDS. See for example the methods in 7.3;
 a semi analytical model for the extended product considering the extended product approach
(EPA) as described in Clause 7, based on the eight torque versus speed operating points as
specified according to EN 50598-2 for the motor system;
 a method for determining an energy efficiency indicator for the extended product under their
responsibility; see Annex B for example.
NOTE The motor system data might consist of PDS data as well as individual data for CDM and motor. EN 50598-2 provides
information about the determination of PDS data based on individual motor and CDM data.
4.3 Elements included in the extended product approach
The semi analytical model (SAM) model of the driven equipment developed by the technical
committee responsible for the extended product combines the information given by the CDM/PDS
manufacturer according to EN 50598-2 in the operating points for the motor system. Other operating
points can be calculated if needed according to 7.3.
To determine the overall losses or efficiency of an extended product implemented in an application it is
required to go through several steps:
Several elements shall be combined:
a) The SAM of the Motor System, specified in EN 50598-2, giving its relative losses at several
standardized operating points. The motor system can be a power drive system (PDS) or can
consist of a motor and a motor starter (contactor, softstarter…):
1) When the motor system is a PDS, the calculation of the losses is the sum of the losses of the
CDM and motor or the total losses of the complete PDS.
2) When the motor system is based on a motor starter, the calculation of the losses is simpler;
there is no need to use any reference motor starter.
b) The SAM of the driven equipment (pump, compressor, fan…), giving the losses or efficiency of
the load machine at typical operating points. It is the responsibility of the associated product
committee.
c) The extended product approach, combining the SAM of the motor system and the SAM of the
driven equipment (and also if necessary relative losses for the coupling). It is the responsibility of
the manufacturer of the extended product. The extended product approach uses application-
related data (required operating points, duty profile, working time …), in order to determine the
energy efficiency index of the application. This index allows comparing the energy efficiency
aspects of several motor systems for a given application, or several modes o
