IEC 61800-9-2:2025 Systemas de accionamiento eléctrico de potencia con velocidad ajustable (PDS) - Parte 9-2: Diseño ecológico para sistemas de motores - Determinación y clasificación de la eficiencia energética. Versión consolidada
IEC 61800-9-2:2023+AMD1:2025 This part of IEC 61800 specifies energy efficiency indicators of power electronics (complete drive modules (CDM), input or output sub drive modules (SDM), power drive systems (PDS) and motor starters, all used for motor driven equipment. This document specifies the methodology for the determination of losses of the complete drive module (CDM), the sub drive module (SDM), 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 load equipment. It provides a link for the energy efficiency evaluation and classification of the extended product. The methodology of the extended product approach and the semi analytical models are defined in IEC 61800-9-1. The structure of this document is as follows: • the losses of standardized PDS, standardized reference CDM (RCDM) and the mathematical model for their calculation are given and classified; • the reference motor (RM) and the reference CDM (RCDM) are defined. They are used for determining the efficiency class of a PDS if either the physical motor or physical CDM is unknown; • the requirements for the determination of the losses of a physical PDS and a physical CDM including correction factors for other types of CDM, not defined as RCDM or SDM, are given and compared to the IES class limits and the RCDM; • the requirements for type testing and user documentation are given; • some exemplary losses of an overall system are illustrated in annexes; • information about system and drive topologies are given in annexes. Specific data for the RCDM and RM, limits for the PDS and IE/IES classes are given for low voltage (100 V up to and equal to 1 000 V), single axis AC/AC power drive systems with three phase motors. Geared motors are treated as standard motors when motor and gearbox can be separated. A methodology is given in addition how this reference data can also be applied to other topologies like AC/DC or DC/AC converters. All provided reference data is derived from PDS with induction motors. They can be used for various types of PDS with other types of motors as well, for example but not limited to, electronically commutated motors (ECM), permanent magnet motors (PM) or synchronous reluctance motors (SYN-RM), and line-start permanent magnet motors (LSPM). PDS requirements in this document only apply to PDSs that are placed on the market as one single product, i.e. combination of motor and CDM that are not intended to be used separately. CDM requirements only apply to a CDM where the included SDMs have not already been evaluated according to SDM requirements. The following equipment is excluded from the scope: • high voltage CDM, SDM and PDS with a rated voltage above 1,0 kV AC or 1,5 kV DC;
