Transition to IE3

As of then, motors with a performance between 7.5 and 375kW designed for continuous operation with a constant load must comply with the energy efficiency standard IE3. Alternatively, motors that meet the IE2 efficiency level and are equipped with a variable speed drive can be used.

In order to make the changeover easy for machine and plant manufacturers, the dimensions of NORD Drivesystems’ IE3 motors will remain largely identical to those of IE2 models, allowing for retrofitting without any modifications to machines and plants.
