M/476 - Speed & Power Drive System

This part of EN 50598 provides the general requirements to energy efficiency standardization for any extended product by using the guidance of the extended product approach (EPA).
It enables product committees for driven equipment with embedded motor systems (so called extended products) to interface with the relative power losses of the embedded motor system (e.g. PDS) in order to calculate the system energy efficiency for the whole application.
This shall be based on specified calculation models for speed/load profiles, the duty profiles and relative power losses of appropriate torque versus speed operating points.
This part of EN 50598 specifies the methodology of determination of losses of the extended product and its sub-parts.
This part of EN 50598 does not specify requirements for environmental impact declarations.

This part of EN 50598 specifies the process and requirements to implement environmental conscious product design principles, to evaluate eco-design performance and to communicate the potential environmental impacts for power driven systems, motor starters, power electronics (e.g. Complete Drive Modules, CDM) used in motor driven applications (motor driven loads) for low voltage (less than 1000V) and in the power range of 0,12 kW up to 1000 kW during the whole life cycle.
It defines the content for 2 different environmental declaration types:
   The basic version, an environmental declaration type II, with basic data and qualitative statements on eco design, as defined in EN ISO 14021
   The full version, an environmental declaration type III as defined in EN ISO 14025, including quantitatively evaluated potential environmental impacts. For that product category rules [PCR] for motor system components are included to assure an harmonized life cycle assessment methodology.
This part of EN 50598 is harmonized with the applicable generic and horizontal environmental standards and contains the additional details relevant for the above mentioned products.
This part of EN 50598 applies to the components of a motor system as defined in EN 50XXX 1.

IEC 61800-9-2:2017 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.

This part of EN 50598 specifies the process and requirements to implement environmentally conscious product design principles, to evaluate ecodesign performance and to communicate potential environmental impacts for power electronics (e.g. complete drive modules, CDM), power drive systems and motor starters, all used for motor driven equipment in the power range of 0,12 kW up to 1 000 kW and low voltage (up to 1 000 V) applications over the whole life cycle. It defines the content for 2 different environmental declarations based on EN ISO 14021: - The basic version - which, in this context, will be referred to as an environmental declaration type II, with basic data and qualitative statements on ecodesign. - The full version - which, in this context, will be referred to as an environmental declaration type II+, based upon a life cycle assessment and including quantitatively evaluated potential environmental impacts. For that the general principles of EN ISO 14025 are taken into account and product category rules [PCR] for motor system components are included to ensure a harmonized approach. This part of EN 50598 is harmonized with the applicable generic and horizontal environmental standards and contains the additional details relevant in this context for the above mentioned products.

This European Standard specifies the energy efficiency indicators for power electronics (e.g. complete drive modules, CDM), power drive systems and motor starters, all used for motor driven equipment in the power range of 0,12 kW up to 1 000 kW. It specifies the methodology for determination of losses of the complete drive module (CDM), the power drive system (PDS) and the complete 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 part of EN 50598 proposes a methodology for characterization of the best energy efficiency solution to be implemented. This depends on the motor driven system architecture, the speed/load profile and the operating points over time of the driven equipment. The methodology of the extended product approach and the semianalytical models are defined in Part 1 of the series. The structure of this EN 50598 contains the following: - the losses of a standardized reference PDS (RPDS) and the mathematical model for their calculation are given and classified; - the reference load/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 determining the losses of a real PDS are given and are classified in comparison to the RPDS; - the requirements for the type testing and the content of user documentation; - some illustrations of losses in an overall system as an example are given 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 voltages (100 V up and equal to 1 000 V), single axis AC/AC power drive systems with three phase induction motors. Geared motors need to be treated as standard motors. All provided reference data is derived from PDS with induction motors, but valid for all types of PDS with other types of motors. High voltage equipment does not need to be assessed in this edition of the document. In prEN 50598-3, the methodology for eco-design for environmental impact is defined. NOTE The 50598 series does not cover energy efficiency classification of driven equipment, but provides input for the assessment of extended product approach.

This European Standard provides a general methodology to energy efficiency standardization for any extended product including a motor system by using the methodological guidance of the extended product approach (EPA). It enables product committees for driven equipment with included motor systems to interact with the relative power losses of the included motor system (e.g. PDS) in order to determine the system energy efficiency aspects for the extended product by calculation. This should be based on specified calculation models for speed/load profiles, the load-time profiles and relative power losses of appropriate torque versus speed operating points. This part of the EN 50598 series specifies the methodology of determination of losses of the extended product including a motor system and its sub-parts. This framework is explained by an example for pumps. This part of the standard does not specify requirements for environmental impact declarations.
