NORD Drivesystems , the Australian subsidiary of major helical geared motor manufacturer, Getriebebau NORD Gmbh & Co KG has introduced IEC standard electric motors to the Australian market.  

Available in Australia through NORD Drivesystems AU, the IEC standard electric motors come with B3 foot mounting, or B14A/ B5 flange mounts. The initial standard stock encompasses 415 Volt, 3 phase power supply with 4 pole stators, and a size range between 0.12 kW and 30 kW.  

The IEC standard electric motors are available from NORD Drivesystems in increased IP protection ratings from IP55 to IP66.  

NORD electric motors are completely assembled on the electric motor assembly line located at their Derrimut, Victoria factory. Featuring an aluminium stator frame exterior, the electric motors come with a corrosion resistant aluminium finish as standard but can also be supplied in finishes including enamel and acrylic paint, two pack epoxy paints, and the NORD Severe Duty (NSD) stainless steel coatings.  

NORD’s IEC standard electric motors also come with options such as IP55 and IP66 electromagnetic brakes, back stops, pulsed incremental encoders, alternative terminal boxes, tropic proofing, forced fan cooling and cast iron fans among others.  

All NORD electric motors supplied to the Australian market have thermistors as standard, and are suitable for operation by a frequency inverter.  

NORD now presents their electric motors in an improved IE2 design to meet European IEC 60034-30:2008 standard. The IE2 design complies or exceeds the current Australian efficiency standards also known as MEPS2 or MEPS AS/NZS1359.5. IE2 is also equal to the NEMA Energy Efficiency/EPACT standards.  

Key features of NORD IE2 electric motors:  

  • Meets European IEC 60034-30:2008 standard, also known as IE2
  • Achieves increased efficiency through the use of more active materials including higher quality sheetmetal and copper filling factors
  • Produces less heat and has higher thermal reserves, allowing the drive units to be designed to enable the partial load range to be shifted upwards
  • Lower losses allow operation above the rated power
  • Allows customers to include the operating range in the planning and design for their applications
  • Increased start-up torque and breakdown torque
  • Permanent reserves in the motor allow designs to be optimised while providing economic benefits
  • Can be applied for a wider voltage range
NORD Drivesystems plans to introduce electric motors that meet efficiency class IE3 standard, which is equivalent to the NEMA Premium Efficiency standard.
