Small motors added to NORD’s IE3 premium efficiency range

NORD Drivesystems has expanded their
IE3 premium efficiency motor range with the addition of smaller motor powers. NORD’s
small motors have been introduced as an alternative to their comprehensive IE2
motor range, with the smaller-sized IE3 portfolio featuring rated power from
0.12 kW to 0.75 kW. The small motors find broad use in many drive applications,
allowing entire plants to be equipped with eco-friendly, highly efficient drive
systems.

While 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 only recently been
introduced into the international standard IEC 60034-30-1, there is no
immediate need legally to act on motors this small as IE3 requirements within
the EU only apply to motors rated at 7.5 kW or higher. Even the revised
requirements of 2017, which cover smaller performance ratings, will only extend
to 0.75 kW or larger systems.

However, the European Council
for an Energy Efficient Economy (ECEEE) has identified in its Lot 30
consultation forum that motors below 750 W should be included in the quest to
have only one eco-design regulation on electric motors ranging from 0.12 kW to
1000 kW.

The latest IE3 premium
efficiency motors address the needs of companies that are concerned about the
environment. NORD supplies the compact IE3 motors in IEC frame sizes; therefore,
changing the specifications to IE3 will not require physical design changes to
machinery and equipment.

NORD manufactures a
comprehensive range of IE2, IE3 and IE4 efficiency class motors up to 200 kW,
gearmotors up to 242,000 Nm and frequency inverters up to 160 kW.
