IE4 Electric Motors

IE4 is the "Super Premium Efficiency" class in IEC 60034-30-1 and represents a step beyond IE3. IE4 electric motors minimise energy losses and deliver significant savings for facilities with high electricity consumption. Rising energy prices, sustainability targets and tightening regulations are rapidly increasing demand for IE4 motors.

The Difference Between IE4 and IE3

IE4 motors have lower losses and higher rated efficiency than IE3. This difference translates into notable annual energy savings, especially for high-power, continuously running motors. Although the initial cost is somewhat higher than IE3, the difference is recovered quickly in most applications thanks to energy savings.

Why IE4?

Higher efficiency: lower losses and energy costs than IE3.
Sustainability: reduces carbon footprint and energy consumption.
Long life: lower operating temperature extends winding and bearing life.
Fast payback: the investment returns quickly in 24/7 facilities.
Future-ready: compliance with tightening efficiency regulations.

Application Areas

IE4 motors are ideal for continuously running pump and fan systems, compressed-air (compressor) lines, water and wastewater plants, HVAC and general-purpose industry. Wherever efficiency is a priority, IE4 minimises the total cost of ownership (TCO). For top efficiency see the IE5 motors class, and for harsh conditions the cast iron body motors.

Technical Options

The DRG Motor IE4 series offers cast iron body, three-phase construction and various speed/power combinations (3000–750 rpm) for a wide range of uses. Efficiency increases further when used with a variable frequency drive (inverter).
