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 IE2 class is mandatory for all new motors since 16 June 2011. The IE3 class will be ...
