IE4 represents the super premium efficiency class in IEC 60034-30-1 and sits one step beyond IE3. For facilities where energy cost weighs heavily on the budget, IE4 pushes losses lower still and grows the annual saving. As a manufacturer-supplier that builds the IE4 series on its own production line and delivers from stock, HEM Motor offers this class with both technical and commercial advantages.
Our IE4 range spans 0.25 kW to 355 kW, with a Ø100 mm shaft diameter on the largest frame. The motors are built with IP55 protection and Class F insulation, and slip near full load is about 4%. Paired with a frequency inverter, system efficiency rises further, yielding extra savings in variable-load applications.
Although the initial cost is slightly above IE3, in continuous applications the gap is closed by savings. For top efficiency see our IE5 series, and for harsh environments our cast iron body models. For the right IE4 selection and a quote, call +90 (532) 345 49 86 or use our contact page.
When you run an IE4 super premium motor with a frequency drive (VFD), there is a risk of losing in the bearings what you gain in efficiency, because of bearing currents. The high-f... More Details
