The DRG Motor IE3 electric motor series is a product built on the Premium efficiency class of IEC 60034-30-1, gathering a wide power range under a single design framework. The series fully meets the minimum efficiency requirements of modern plants.

What Powers and Speeds Does the Series Cover?

The IE3 series spans from 0.55 kW to 355 kW and offers 2, 4 and 6-pole options. Two poles give 3000 rpm, four poles 1500 rpm and six poles 1000 rpm synchronous speed, so it answers a broad range of applications from high-speed compressors to low-speed mixers.

A Common Mechanical Platform

All models in the series share a cast iron frame, IP55 protection and Class F insulation. This common platform simplifies spare-part compatibility and streamlines maintenance stock. As the terminal box and mounting interfaces follow standard IEC dimensions, on-site replacement is straightforward.

How Efficiency Shows in Operation

The IE3 class delivers the same shaft power with lower losses. In pump, fan and conveyor drives that run many hours a day, this difference turns into a tangible saving in annual energy consumption. The gain is most pronounced in continuously running S1-duty systems.

Choosing the Right Model from the Series

The right model is chosen by setting the required power, speed and mounting type (B3/B5/B14) to the application. DRG Motor helps you identify the model from the IE3 series that suits your plant and provides a quotation.
