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 duty 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.
