The new Standard EN 50598 consisting of 3 parts specifies Ecodesign requirements for
drive systems, motor starters, power electronics and their driven devices.
General requirements for establishing
standards for the energy efficiency
of electrically operated equipment
according to the expanded product approach
(EPA) with semi-analytic models
This part specifies the procedure for determining
the losses of the extended product
approach and its components. A product
committee is thereby able to couple
the power losses of the installed electrical
motor system with any type of plant driven
thereby and determine the system energy
efficiency for the extended product.
Indicators for the energy efficiency
of drive systems and motor starters.
This part of EN 50598 (EN 50598-2) specifies the procedure
for determining the losses of the complete
motor system, power drive system
(PDS) and CDM (Complete Drive Module) in
8 application-relevant operating points for
motor drive applications in the power range
from 0.12 kW to 1,000 kW.
In addition losses of the reference motor,
reference CDM and the reference PDS
are laid down for the specified 8 operating
points and new efficiency classes are redefined
for the drive system PDS (IES0-IES2)
and also for the CDM (IE0-IE2). As reference
motor (RM) the losses are derived
from four-pole asynchronous motors with
50-Hz-IE2 efficiency values according
to EN 60034-30 and various factors described
in this Standard.
Quantitative Ecodesign approach by
means of eco balancing including product
category regulations and their environmental
This part of the Standard deals with the
topic “Ecodesign” and considers essential
environmental aspects in the product
design of motor systems (motor starter/
drive controller, motor).
