Title Ecodesign for power drive systems, motor starters, power electronics and their driven applications - Part 1: General requirements for setting energy efficiency standards for power driven equipment using the extended product approach (EPA), and semi analytic model (SAM)
Project Number 24602
Abstract/Scope 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.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
