Why you should upgrade to IE5 ultra-premium motor efficiency

While electric motors keep the world turning safely and reliably, there is a price to pay in terms of energy consumption and associated CO2 emissions. Around 70 percent of all electricity used by industry is consumed by electric motor systems. 

The EU Ecodesign Regulation addresses this for
low-voltage motors by establishing and enforcing International Efficiency (IE) classes defined by the International Electrotechnical Commission (IEC). From July 2021, it sets IE3 as the minimum standard, including motors used with VSDs. There is also the IE5 ultra-premium rating that goes well beyond the EU Ecodesign regulation, but
some manufacturers are already supplying motors compliant with it. Industrial operators can upgrade now and enjoy practical and economic advantages – as well as demonstrating their environmental responsibility.

IE5 SynRM motors can reduce energy losses by 40 percent and significantly lower energy consumption, compared to the commonly used
IE3 induction motors. Exact energy savings vary with applications and conditions, but industrial case studies with SynRM motor and VSD packages have shown typical reductions in energy bills of from 14 to 25 percent, compared to the replaced motors.

If 80 percent of today’s installed industrial motors were
replaced by IE5 units, the estimated annual energy saving would equate to the annual power consumption of Poland. There are also other substantial benefits to be gained from IE5 SynRM motors, including lower maintenance needs, higher reliability, longer equipment life, and better performance...
