The 4E Electric Motor Systems Annex (EMSA) provides a platform for an in-depth technical and policy exchange between members and is a vehicle for collaborative projects. Some of its research results are made publicly available. Up

What are the lessons learned after working more than 10 years with motor standards? More about this and other questions in the webinar held by Conrad U. Brunner on 10 June 2020.

On 9 and 10 June 2020, an International Motors Workshop will take online, organized by the European Cooper Institute and IFP Energies nouvelles.

The Motor Summit 2020 Internationals brings together selected international experts, industry representatives, standards developers and policy makers to exchange information on the latest

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.

The 11th international conference on Energy Efficency in Motor Driven Systems will be held on 17 to 19 September 2019 in Tokyo, Japan.

The next international conference on Energy Efficiency in Motor Driven Systems will take place on 17 – 19 September 2019 in Tokyo Japan.

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).

A Policy Brief explaining the activities of EMSA and the focus of its work for 2019 – 2024 is now available.

EMSA in cooperation with IEC has launched an international Round Robin testing program for converters losses. A workshop with first results will be held on 13 November 2018 in Zurich, Switzerland, at the Motor Summit.

EMSA shows in this Audit Guide important organisational and technical considerations for performing a motor systems audit, using relevant standards and tools.

What standards and regulations are in place for pumps, fans and compressors? How to increase their international alignment to maximize energy savings?

United for Efficiency released a Policy Guide on Accelerating the Global Adoption of Energy-Efficient Electric Motors and Motor Systems.
