International Standard IEC 61800-9 (EN 50598)
The European Standard EN 50598 Part 1 and Part 2 has now been transferred to the International Standard IEC 61800-9. The new IEC standard consists of 3 parts and specifies Ecodesign requirements for drive systems, motor starters, power electronics and their driven devices.
Part 1 (IEC 61800-9-1 and EN 50598-1)
General requirements for establishing standards for the energy efficiency of electrically operated equipment according to the expanded product approach (EPA) with semi-analytic models (SAM).
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.
Part 2 (IEC 61800-9-2 and EN 50598-2)
Indicators for the energy efficiency of drive systems and motor starters.
This part of IEC 61800-9 (IEC 61800-9-2) and 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 60034-30-1 and various factors described in this Standard.
Part 3 (only EN 50598-3)
Quantitative Ecodesign approach by means of eco balancing including product category regulations and their environmental declarations content.
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).
