IE1 standard efficiency motors from 0.75kw power should no longer be marketed within the European Union and the United States (except for uses in certain environmental conditions and services as clearly described on our catalogue) . They are mainly used to be exported to markets where they are not yet mandatory and minimum efficiency levels and efficiency class IE1 are still accepted .
IE2 efficiency motors are built in accordance with new EC Regulation 640/2009 which set the minimum level of energy efficiency for electric motors for being sold within Europe ( and other countries ) and became mandatory from June 2011 . Therefore, from this date, three phase motors, single speed (2, 4 or 6 poles) , with a rated power from 0.75 kW, rated voltage up to 1,000 V and characteristics of continuous operation , sold and installed in Europe must meet IE2 efficiency requirements established by this standard.
From January 2015 even the IE3 efficiency shall come into force for engines from 7.5kw to 375kw sold within the European Union.
