From July 2021, a new Ecodesign regulation will come into force for low-voltage induction electric motors rated up to 1kV AC and, for the first time, for variable speed drives (VSDs). 

Are you ready for the introduction of the latest energy efficiency regulations that will come into force in July 2021?

Speak to Varicon, your authorised Danfoss Drives DrivePro® Service Partner, to find out more about the Ecodesign directive and why it is so important for your business to meet the updated standards.

This significant change will take place on 1 July 2021, when the Ecodesign Regulation (EU) 2019/1781 will come into effect. The regulation will encompass a range of motor types that were excluded from earlier efficiency requirements.

From July 2021 onwards, the following updates will be implemented:

IE3 efficiency levels will be mandatory for:

•  motors with rated outputs from 0.75–1,000kW

•  three-phase, single-speed motors for 50Hz, 60Hz, 50/60Hz operation up to 1kV

•  safe area motors and motors for Ex t, Ex ec, Ex d and Ex de, rated for S1, S3 > 80%, S6 > 80% duty

•  totally enclosed, air-over (TEAO) motors

•  brake motors with external brakes.

IE2 efficiency levels will be required for three-phase motors from 0.12–0.75kW.

Regarding VSDs, the earlier Regulation 640/2009 (which allowed IE2 motors to be used with VSDs) did not stipulate any efficiency requirements. This has now changed. From July 2021, three-phase standard drives (diode rectifier) from 0.12–1,000kW are included. For low-voltage VSDs, the following are excluded from the regulation: regenerative drives; low-harmonic drives (with a THD of less than 10%); multiple AC-output drives; and single-phase drives. Several other drive types are also excluded, including MV drives, DC drives and traction drives.

The new regulations will see additional updates from 1 July 2023, when IE4 will become mandatory for safe area three-phase motors with 2, 4, or 6 poles from 75-200kW. The coverage will also extend to Ex eb motors and single-phase motors.
