The IEC Advisory Committee on Energy Efficiency (ACEE) TG6 launched on 20 September 2019 in Tokyo the project ‘Coordination and Alignment of IEC and ISO Standards for Energy Efficient Electric Motor Driven Systems’ (CAISEMS).

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.

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.

The latest addition to the family of tools by EMSA is the hydraulic calculator: DTI-Hydracalc

At the end of 2017, EMSA, in a unique collaboration with IEC SC 22G WG18, has launched a three-year Round Robin program for converter losses (RR’C). The report of RR’C phase 1 is now available.

This SEAD Policy Exchange Forum call will explore the different challenges and what it is required to build an effective program for promoting energy efficient electric motors.

On 19 March 2019, a series of technological innovations in the field of industrial electric motors will be presented during a workshop in Brussels, organized by the European Cooper Institute.
