Adjustable speed electrical power drive systems (PDS) - Part 9-2: Ecodesign for motor systems - Energy efficiency determination and classification (IEC 22G/522A/CDV:2025); German and English version EN IEC 61800-9-2:2025/prA1:2025
Abstract
This part of IEC 61800 specifies energy efficiency indicators of power electronics (complete drive modules (CDM), base drive modules (BDM) and input or output sub drive modules (SDM)), 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/torque 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. Corrections were originally intended to be part of currently published Edition 2 but were not able to be included.
