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.

An IE5 synchronous reluctance (SynRM) motor is not a stand-alone product; it is part of a package made up of the motor and the variable frequency drive (VFD) that runs it. For this... More Details
The true cost of an electric motor reveals itself not only at the moment of purchase but throughout its service life and at the end of its life. IE5 Ultra Premium synchronous reluc... More Details
When buying an electric motor, most people look at the efficiency figure on the nameplate. An IE3, IE4 or IE5 marking seems to tell the motor's entire story. Yet as a company that ... More Details
What actually turns a machine is not power, but torque. A common shorthand in engineering is to refer to motors only by their kilowatt value; yet two motors marked "22 kW" in a cat... More Details
The IE5 synchronous reluctance (SynRM) motor is the most common representative of the ultra-premium efficiency class in the field, and unlike a classic asynchronous motor it can ne... More Details
IE5 synchronous reluctance (SynRM) motors offer an advantage that is often overlooked alongside their ultra premium efficiency: noticeably quieter operation. In HVAC plants near ho... More Details
IE5 synchronous reluctance (SynRM) motors stand out not only for their ultra-premium efficiency class but also for the dynamic torque behaviour they gain through drive control. In ... More Details
An IE5 synchronous reluctance (SynRM) motor delivers its ultra-premium efficiency only when driven by a correctly matched variable frequency drive (VFD); therefore the DC bus volta... More Details
