EU MEPS (the European Minimum Energy Performance Standard
scheme) sets mandatory minimum efficiency ratings for electric motors sold in
European markets. Using efficiency classes defined in international standard IEC
60034-30, the ratings cover single-speed, three-phase induction motors up to
375kW. Efficiency classes exist as part of a global effort to reduce energy
consumption and CO2 emissions. Higher-efficiency motors are beneficial to the
end-user as they provide long-term energy savings and improved performance.
Under EU MEPS, electric motors are graded for efficiency as
follows:
IE1 – Standard efficiency
As of 16 June 2011, all electric motors sold in the EU must
meet the IE2 efficiency level as a minimum. Therefore, IE1-rated motors are now
obsolete.
IE2 – High efficiency
This standard is comparable to the old Eff1 rating. From 1
January 2015, motors with a rated output of 7.5 – 375kW must meet EITHER the
IE3 efficiency level (see below) or the IE2 level if fitted with a
variable-speed drive.
IE3 – Premium
efficiency
From 1 January 2017, motors with a rated output of 0.75 –
375kW must meet either the IE3 efficiency level or the IE2 level if fitted with
a variable-speed drive.
IE4 – Super premium
efficiency
This level has yet to be officially defined by the IEC,
although some suppliers are already rating their most efficient motors as IE4.
