The IE3 Premium efficiency class is today the most common reference point for industrial motors under the IEC 60034-30-1 standard. The IE3 electric motors DRG Motor supplies in Izmir run with lower losses than their IE2 counterparts and are designed to improve the energy balance of plants in continuous production.

What Does IE3 Premium Mean?

IE3 indicates that the efficiency the motor reaches at rated load meets the Premium threshold defined in the standard. In practice this means the copper losses in the windings and the iron losses in the core are reduced compared with IE1 and IE2, so the motor produces the same mechanical power with less grid energy.

Technical Construction of DRG IE3 Motors

The DRG Motor IE3 series is offered on a 400 V / 50 Hz supply with 2, 4 and 6-pole options (3000, 1500 and 1000 rpm). Class F insulation, IP55 protection and S1 continuous duty are standard. The cast iron frame provides mechanical strength under heavy industrial conditions.

Where Does It Stand Out?

IE3 motors are the most sensible choice on pumps, fans, compressors and conveyors that run many hours a year. On these loads the small gain in efficiency, multiplied by the running hours, turns into meaningful energy savings and keeps the motor running cooler.
