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.The structure of this document is as follows:• the losses of standardized reference PDS (RPDS), 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 and can be used to determine the efficiency class of a motor system when one of its constituents is unknown,• the requirements for the determination of the losses of a real PDS and a real CDM are given and compared to the reference RPDS and 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 power losses of RCDM, RM, RPDS 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.All provided reference data is derived from PDS with induction motors. It may be used for all types of PDS with other types of motors as well.The application of this document to the following equipment may be technically possible but is not mandatory:• High voltage CDM and PDS with a rated voltage above 1 000 V AC,• Low voltage CDM and PDS with a rated voltage below 100 V AC,• High power PDS above a rated power of 1 000 kW,• High power CDM above a rated apparent output power of 1 209 kVA,• Low power PDS below a rated power of 0,12 kW,• Low power CDM below a rated power of 0,278 kVA,• CDMs other than those converting electrical AC power into one single AC output,• PDSs other than those converting electrical AC power into one single mechanical rotating shaft,• PDSs and CDMs that are able to regenerate energy back into the AC power supply,• PDSs and CDMs having an input current with a THC (according to the definition in IEC 610003-12) of less than 10 %,• PDS with geared motors where motor and gearbox cannot be separated, for example because of a common housing,• Servo PDS (consisting of frequency converter, motor and position feedback sensor),• PDSs that are not put on the market as one single product.NOTE IEC 61800-9 (all parts) does not cover energy efficiency classification of driven equipment but provides input for the assessment according to the extended product approach.
