Neue EU Verordnung 2019/1781 für mehr Energieeffizienz von Elektromotoren und Drehzahlregelungen
New EU Regulation 2019/1781 for more energy efficiency of electric motors and speed controls
The EU Commission is striving for a climate-neutral economy in Europe. In doing so, it would like to fulfill its commitments from the 2015 Paris Climate Conference. The goals to be achieved by 2030 are:
- a reduction in greenhouse gas emissions by 40% (compared to 1990),
- a larger proportion of energy obtained from renewable sources and
- an increase in energy efficiency of 32%.
Regulation 640/2009, which is valid until June 30, 2021, has resulted in savings of approximately 57 TWh annually by 2020. An increase in energy efficiency is possible if additional motors that previously did not fall within the scope of Regulation (EU) 640/2009, as well as speed controls, were included in new regulations.
Therefore, with the new Regulation (EU) 2019/1781, the eco-design requirements for engines were adjusted and new ones were set for speed controls. The new Regulation (EU) 2019/1781 will take effect in 2 steps
Regulations come into force on July 1st, 2021
The first step came into force on July 1st, 2021 and includes the following adjustments to engines:
- Three-phase motors with squirrel cage rotor 50 Hz, or 50/60 Hz, extension to 60 Hz;
- IE3: Expansion of the rated power from ≥0.75 kW to 1,000 kW;
- Specified for continuous operation S1, S3 ≥ 80% ED, extension to S6 ≥ 80% ED;
- Number of poles 2, 4, 6, extension to 8;
- Inclusion of the rated power from 0.12 kW to <0.75 kW with IE2;
- Inclusion of motors for potentially explosive areas with the exception of Ex eb;
- Inclusion of brake motors (where the efficiency can be determined without a brake);
- Inclusion of Totally Enclosed Air Over engines (TEAO) (IC 418).
For frequency converters (speed controls) it has been newly stipulated that the power losses must not exceed a maximum value and correspond to efficiency class IE2.
Regulations come into force on July 1st, 2023
The full implementation of Regulation (EU) 2019/1781 will take place with the 2nd step from July 1st, 2023. From this point onwards, the following adjustments will come into force:
- Introduction of efficiency class IE4 for motors with rated outputs from 75 to 200 kW with pole numbers 2, 4 and 6, which are not brake motors and are not Ex eb or Ex motors of other types of ignition protection;
- Inclusion of explosion-proof motors with type of protection Ex eb with rated outputs of 0.12 kW to 1,000 kW with an efficiency class IE2;
- Single-phase motors ≥ 0.12 kW with an efficiency class IE2.
This means that a large number of engines now and in the future fall within the scope of the regulation. This also includes, for example, engines that are used in railway and shipbuilding applications.
For the first time, a regulation for the delivery of replacement engines was also made. Replacement motors can be delivered if they are used to replace motors that were installed before July 1st, 2021 or July 1st. delivered in 2023 must be replaced by equivalent engines.
Regulation (EU) 2021/341 also came into force on July 1, 2021. Article 2 contains important additions and corrections to Regulation (EU) 2019/1781. The most important points are
- the addition of minimum efficiency tables for 60 Hz of the efficiency classes IE2, IE3 and IE4,
- the specification of the dates for the availability of replacement engines and
- the use of QR codes and a link in connection with the provision of product information to customers.
VEM already meets these requirements. The VEM sales staff is available to provide further information on the energy efficiency of low-voltage motors. You are also welcome to send us your questions at newsletter@vem-group.com and we will try to answer them as best we can in our next issue of Impulse.
