VEM IE2 INDUSTRIAL MOTORS

Surface cooled squirrel cage motor for frequence converter operation

The validity of the currently existing Regulation (EC) No 640/2009 on the ecodesign of electric motors and the regulation contained therein to use an IE2 motor with speed control (VSD) in the power range 0.75 to 375 kW will end with effect from 30th June 2021.

VEM will withdraw the IE2 portfolio (incl. Ex eb) from the range as early as 31st March 2021, thus already reacting to the influences from the market.

Standard motor after 1.7.2021 will be the IE3 motor. IE4 and IE5 are also good choices.
