The highest efficiency tier obtainable from an electric motor today is IE5. Defined as ultra premium efficiency in the IEC 60034-30 series, this class pulls losses clearly below IE4. For facilities where energy plays a leading role in operating cost, IE5 targets both the lowest consumption and the lowest carbon emissions. HEM Motor is a manufacturer-supplier that produces its IE5 motors in-house and delivers them from stock.
This efficiency is achieved through advanced winding design and an optimised magnetic circuit. Our motors are built with IP55 protection and Class F insulation, with slip near full load at about 4%. Getting the most from IE5 usually means running it with a variable speed drive (inverter); this combination lifts system efficiency to its peak in variable-flow systems.
If you want to compare the previous tier, see our IE4 series. Let us calculate together the saving your operation would gain by moving from IE4 to IE5; for the right IE5 power and speed, current stock and a quote, call +90 (532) 345 49 86 or write via our contact page.
