İzmir's port, logistics and extensive organized industrial base keep demand for energy-efficient motors constant. The IE3 premium and IE4 super premium classes are the two main options for this demand, and the right choice depends on a line's running hours and load profile. As an İzmir-based supplier, DRG Motor supplies both classes.

The Difference Between IE3 and IE4

Both classes are defined by IEC 60034-30-1. IE3 offers premium efficiency, while IE4 stands one step higher at super premium efficiency. IE4 motors cut losses further, but the difference turns into meaningful savings mainly on lines that run thousands of hours per year.

Which Class Suits İzmir Industry?

On intermittent or low-hour lines, IE3 is often a balanced choice. By contrast, in continuously running pump, compressor and fan systems, the lower losses of IE4 make a difference in lifetime energy cost.

Shared Technical Features

Both classes are offered on a 400 V / 50 Hz supply with IP55 protection and Class F insulation. Speed options of 2, 4 and 6 poles, along with B3 foot, B5 flange and B14 face mountings, are selected according to the application.
