Think small, but think green: IE3 motors from 0.12kW
12 December 2015
From January 2016, Nord Drivesystems will expand its IE3 premium efficiency motor range to include smaller motor powers. The smaller-sized IE3 portfolio offers rated power from 0.12 kW to 0.75 kW.
Whilst the efficiency percentiles for this performance class have only been defined in the last stage of the European Union Ecodesign Directive for electric motors and have only recently been introduced into the international standard IEC 60034-30-1, legally there is no immediate need to act on motors this small as IE3 requirements within the EU only apply to motors rated at 7.5kW or higher.
Even in 2017, when smaller performance ratings are due to be included, this will only extend to 0.75kW or larger systems. However, the European Council for an Energy Efficient Economy (ECEEE) has identified in its Lot 30 consultation forum that motors below 750W should be included in the quest to have only one eco-design regulation on electric motors ranging from 0.12kW to 1,000kW. Users with a particular concern for the environment and those seeking to maximise efficiency may wish to go beyond current legal obligations.
Nord supplies the compact IE3 motors in IEC frame sizes. Changing the specifications to IE3 is a smooth process that will not require physical design changes to machinery and equipment.
