Nord Drivesystems now provides IE2-compliant three-phase motors delivering outputs as low as 0.55 kW. These models are ahead of the new European energy-saving standard: from June 2011, the IE2 standard is compulsory for motors delivering outputs ≥ 0.75 kW. Similar regulations apply in almost all other markets, with exceptions only in a few Asian countries – in China for instance, the GB18613 norm requires Grade 2 efficiency, a grade similar to IE2, even for small motors ≥ 0.55 kW, starting in July 2011. For energy-saving motors, the manufacturer 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.
