Premium efficiency is the name of the IE3 class in IEC 60034-30-1, and it describes how little energy a motor wastes when converting electricity into mechanical power. Because an IE3 motor carries the same load with lower losses, it runs cooler and draws less electricity. DRG Motor supplies its Premium efficiency-class motors at its plant in Izmir.

What Premium Efficiency Delivers

A motor's efficiency shows how much of the electricity it draws reaches the shaft. In IE3 motors this ratio is higher than in IE1 and IE2 units, so less energy is lost as heat. On a continuously running line, that small percentage difference accumulates over the year into savings that can exceed the motor's purchase price.

The Design That Raises Efficiency

Reaching the IE3 level calls for higher-grade silicon steel, better winding fill and a low-loss rotor design. DRG's IE3 motors are built with a cast iron or aluminium frame, IP55 protection and Class F insulation, a combination that holds efficiency and durability together.

Which Applications Suit It?

The return on Premium efficiency is greatest in long-running drives such as pumps, fans, compressors, conveyors and mills. DRG's IE3 series is offered from 0.55 kW to 355 kW, with 1500 rpm (4-pole) and 1000 rpm (6-pole) options chosen to match the application's speed.

The Right Investment in Premium Efficiency

When choosing a motor, you should look not only at the nameplate power but also at the efficiency class. DRG Motor recommends the Premium efficiency IE3 model that fits your running hours and load profile, so your motor works reliably and economically from day one.
