The final phase of the EU ecodesign regulations, which impose stricter requirements on the energy efficiency of electric motors, comes into force on 1 July 2023. This means that motors between 75 kW and 200 kW sold in the EU must achieve an energy efficiency level equivalent to IE4.
The implementation of Commission Regulation (EU) 2019/1781 laying down ecodesign requirements for electric motors and variable speed drives is entering the final phase.
The updated rules for the energy efficiency of electric motors come into force on 1 July 2023 and, according to the EU’s own calculations, will result in annual energy savings of more than 100 TWh by 2030. This corresponds to the total energy production of the Netherlands. This efficiency improvement means a potential reduction in CO2 emissions of 40 million tonnes per year.
As of 1 July 2023, all electric motors with a power output between 75 kW and 200 kW must have an International Energy Class (IE) equivalent to at least IE4. This will affect a wide range of applications that currently have an IE3 motor.
“We will see a natural phasing out of the IE3 motors that are now subject to the IE4 requirements. But the cut-off date only applies to motors produced after 1 July. This means that customers can still have IE3 motors delivered, for as long as stocks last at Hoyer,” says Rune Svendsen, Segment Manager – Industry at Hoyer.
In addition to the IE4 requirement, Ex eb motors from 0.12 kW to 1000 kW and single-phase motors from 0.12 kW and upwards must as a minimum meet the requirements for IE2
The rules from 1 July 2023
The new regulation applies to induction motors up to 1000 V and 50 Hz, 60 Hz and 50/60 Hz for continuous operation via the mains. The requirements for energy efficiency are:
IE4 requirements
- Three-phase asynchronous motors with 2–6 poles and power output between 75 kW and 200 kW.
- Does not apply to brake motors, Ex eb motors with increased safety and certain explosion-protected motors.
IE3 requirements
- Three-phase asynchronous motors with 2–8 poles and power output between 0.75 kW and 1000 kW, except for motors subject to the IE4 requirement.
IE2 requirements
- Three-phase asynchronous motors with power output between 0.12 kW and 0.75 kW.
- Ex eb motors with increased safety from 0.12 kW to 1000 kW
- Single-phase motors from 0.12 kW to 1000 kW
It is important to note that the regulation also contains other exemptions and special requirements, depending on the use of the motor and environmental conditions.
