Energy efficiency is a main focus area related to CO2 emissions and industrial pollution. Across borders legislation and Minimum Energy Performance Standards (MEPS) are put into force to improve the efficiency of electric motors. The European MEPS are defined in the Ecodesign directive and Hoyer IE4 fulfils these future regulations.

From July 1 2023 all electric motors between 75-200 kW that are commissioned for land-based industrial applications within EU/EEA must be IE4 or higher.
