China to set IE3 as minimum requirement for motors

China updated the draft for the crucial GB 18613 “Minimum allowable values of energy efficiency and values of efficiency grade for motors” with the future motor efficiency requirements. The minimum requirement for 3-phase asynchronous motors between 120 W and 1000 kW will be set at IE3. The formal introduction date has not been set.

EU introduces new motor and converter MEPS from 2021

The European Union published on 25 October 2019 the result of the revision of the Commission Regulation (EC) 640/2009 for electric motors. The new Commission Regulation (EU) 2019/1781 will require minimum requirements for a wider scope of motors (0.12 kW – 1000 kW), will also include 8-pole motors and will abolish the former requirement of an IE2 motor plus a converter instead of IE3. Also, maximum losses for converters between 0.12 kW and 1000 kW at IE2 are requested. From 2023, IE4 will be required for motors between 75 kW and 200 kW.

Preliminary results of Global Round Robin for Converters

The preliminary results of the Global Round Robin testing program for converters losses show a high repeatability of the proposed uniform testing protocol and confirm that the 9 converters tested have much lower losses than the IE1 reference values in IEC 61800-9-2 (edition 1).
