Part 30

IEC 60034-30 specifies energy-efficiency classes for single-speed, continuous duty(S1), three-phase, cage-induction motors with 2, 4 or 6 poles. It classifies five classes: IE1 (standard), IE2 (high) and IE3 (premium), IE4 (super premium efficiency), IE5 (ultra premium efficiency). For each class the efficiency is defined for a rated output range from 0.75 to 375 kW. In the
European Community The European Economic Community (EEC) was a regional organisation created by the Treaty of Rome of 1957,Today the largely rewritten treaty continues in force as the ''Treaty on the functioning of the European Union'', as renamed by the Lisbo ...
the IE2 class is mandatory for all new motors since 16 June 2011. The IE3 class will be mandatory from 1 January 2015 (7.5–375 kW) and 1 January 2017 (0.75–375 kW). From June 1, 2021, three-phase motors from 0.75 kW to 1000 kW must meet at least IE3 efficiency. Electric motors from 0.12 kW to 0.55 kW must meet at least class IE2 efficiency.Commission Regulation (EU) No 1781/2019
'' laying down ecodesign requirements for electric motors and variable speed drives pursuant to Directive 2009/125/EC of the European Parliament and of the Council, amending Regulation (EC) No 641/2009 with regard to ecodesign requirements for glandless standalone circulators and glandless circulators integrated in products and repealing Commission Regulation (EC) No 640/2009''
PDF, 1 October 2019 From July 1, 2023, at least efficiency class IE4 will be required for electric motors in 2/4/6-pole versions from 75 kW to 200 kW. At least IE2 efficiency will be required also for single-phase motors from 0.12 kW up.
