This you should know regarding new standards for IE classes for electric motors as of 1st July 2023

As of 1st July 2023, the requirements for IE classes of electric motors are further sharpened, making the focus on energy efficient electric motors and solutions even higher.

As machine builder it is important to know the newest rules in order to be prepared for the future and to be compliant with the newest European regulations.

At Fabrika, we offer all motors in accordance with the newest regulations, and we can also help you selecting the right motor for your application.

IE4 motors required from 75 to 200 kW

One of the most important changes as of 1st July 2023 is, that three-phase electric motors ranging from 75 to 200 kW (both effects included) now need to be IE4 for 2-, 4- and 6-poled single speed motors when used inside the EU. Brake motors and ATEX motors are excluded from this point.

Three-phase single-speed electric motors must be least IE3 ranging from 0,75 to 55 kW and from 250 to 1000 kW. This applies to 2-, 4-, 6- and 8-poled electric motors designed for continuous duty, i.e. duty class S1, S3 ≥ 80 %, S6 ≥ 80 %. The supply voltage is up to 1000 V.

Totally Enclosed Non-Ventilated motors (TENV) as well as high-voltage motors are major exemptions from the new regulations.

Single-phase motors and Ex eb motor now also included in IE-classes

As something totally new, single-phase motors are now included in the requirements to the IE classes. Hence, as of 1st July 2023, single-phase motors used within the EU need to be at least IE2 energy efficiency level.

Also ATEX motors of the type Ex eb now need to be at least IE2. This applies to motors rated for operation on 50 Hz, 60 Hz or 50/60 Hz supplies and with effects ranging from 0,12 to 1000 kW.

FACT BOX

IE stands for “International Efficiency”. The current IE classes are defined in EU Directive IEC 60034-30-1:

  • IE1 (Standard Efficiency)
  • IE2 (High Efficiency)
  • IE3 (Premium Efficiency)
  • IE4 (Super Premium Efficiency)

 

The new regulations are based on EU’s eco design. The goal is to reduce CO2 emissions in the industrial sector, where around 8 billion electric motors account for 45 % of the total electrical energy consumption.
