Nord introduces compact high-efficiency motors
14 January 2011
Nord Drivesystems can now supply IE2-compliant three-phase motors delivering outputs as low as 0.55kW. These models are ahead of the new European energy-saving standard; from June 2011, the IE2 standard is compulsory for motors delivering outputs greater than or equal to 0.75kW. Similar regulations apply in almost all other markets, with exceptions only in a few Asian countries.
For its energy-saving motors, Nord uses more active material and higher quality sheet metal with smaller losses and increases the copper filling factors. The improved design results in greater power reserves. Consequently, motors with a smaller power rating can be used in many applications, creating additional efficiency benefits.
These performance improvements stem from a reduced partial load range, in which efficiency is necessarily lower. Whilst NORD will keep on supplying motors compliant with the former EFF2 certification, they will not be labeled thus in the future. For selecting the right drive, NORD provides cutting-edge consultation in line and up to date with the respective national standards.
