This part of IEC 61800 specifies the general methodology 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 connected to motor systems (so called extended products) to interface with the relative power losses of the connected motor system (e.g. power drive system) in order to calculate the system energy efficiency for the whole application.
This is based on specified calculation models for speed/load profiles, the duty profiles and relative power losses of appropriate torque versus speed operating points. This document specifies the methodology of determination of losses of the extended product and its sub-parts. This document is applicable to motor systems operated by a motor starter or by a converter (power drive systems). This document does not specify requirements for environmental impact declarations.
