We would like to inform you that from 1 July 2023, new electric motors with an output between 75kW and 200kW must comply with the IE4 standard.
This as the second stage according to the European Union regulation EU 2019/1781.
Stage 1: all motors between 0.75 – 1,000 kW, 2-, 4-, 6-, and 8-pole, must comply with the IE3 Premium efficiency class from 1 July 2021.
Phase 2: all motors between 75 – 200 kW, 2-, 4-, and 6-pole, must comply with the IE4 SuperPremium efficiency class as of 1 July 2023
As a critical service partner, together with a number of experts, we have our own take on this.
IE4 motors are certainly energetically and therefore economically interesting for a number of applications or in combination with frequency control.
However, there are quite a few applications where the energy costs can increase when using IE4 motors, such as pumps and fans that are directly online.
Due to the higher rated speed of these motors, the power delivered to the output shaft increases, so an IE4 motor may have a net higher energy consumption than an IE3 motor.
A more detailed explanation of this can be found here in this article.
Definitely also take into account that IE4 motors are a lot bigger and heavier and therefore cannot always be installed where an IE3 motor used to be.
If you still wish to purchase IE3 motors, we recommend deciding before the end of March.
Due to the upcoming change in regulations, there is currently a spike in demand and lead times may be longer….
