Adjustable speed electrical power drive systems - Part 9-2: Ecodesign for power drive systems, motor starters, power electronics and their driven applications - Energy efficiency indicators for power drive systems and motor starters

NEMA IEC 61800-9-2-2023 | Status: Active | ID:

This part of IEC 61800 specifies energy efficiency indicators of power electronics (complete drive modules, CDM), power drive systems (PDS) and motor starters, all used for motor driven equipment.
It specifies the methodology for the determination of losses of the complete drive module (CDM), the power drive system (PDS) and the motor system.
It defines IE and IES-classes, their limit values and provides test procedures for the classification of the overall losses of the motor system.
Furthermore, this document proposes a methodology for the implementation of the best energy efficiency solution of drive systems. This depends on the architecture of the motor driven system, on the speed/load profile and on the operating points over time of the driven equipment.
The methodology of the extended product approach and the semi analytical models are defined in IEC 61800-9-1.
