On 1 January 2021, the EU will extend the Ecodesign rules to include new and more ambitious energy requirements for electric motors in the size range 0.12 kW - 1000 kW. The requirements are being implemented to phase out the least energy-efficient motors on the market.
A new and more ambitious ecodesign directive is on the way, covering several types of electric motors. The new rules mean that all electric motors with a power output between 0.75 kW and 1000 kW must have an energy class corresponding to at least IE3. Most OEM’s both within and outside of Europe will therefore be affected by the EU directives.
The amendments will officially enter into force on 1 January 2021 and consist of three phases implemented between 1 July 2021 and 1 July 2023. The directive, which enters into force on 1 January 2021, applies to induction motors for continuous operation via the mains and which have 2, 4, 6 or 8 poles and a power output between 0.12 kW and 1000 kW.
In particular, there are three points to pay special attention to in relation to the new rules:
From 1 July 2021:
All electric motors with a power output between 0.12 kW and 0.75 kW must meet the requirements for energy class IE2, while 0.75 kW to 1000 kW must be in IE3 as a minimum.
From 1 July 2022:
Motor suppliers will be required to test all electric motors based on different speeds, unlike the current situation, in which testing is performed only at full speed and with different loads. This is because more and more VFD-controlled applications are entering the market, running at widely different speeds and loads.
From 1 July 2023:
Ex eb increased safety motors from 0.12 kW to 1000 kW and single-phase motors from 0.12 kW upwards must meet the requirements for IE2. All standard motors from 75 kW to 200 kW must meet the requirements for IE4.
Hoyer Motors recommends that OEM’s start thinking about including more energy-efficient motors in their product designs now, as this will reduce the overall climate footprint of the industry and future-proof products.
“As an OEM, you should already now be conscious of introducing this in your new design. It would be regrettable to spend thousands of engineering hours developing an application that cannot be sold on the market in 2021 because the product is installed with a motor that is not efficient enough,” says Thomas Vase, Product and Application Specialist at Hoyer Motors.
