High-kW IE4 electric motors are designed for energy-intensive plants running long hours that seek the highest point of efficiency. The benefit of the efficiency class grows as power increases, so the IE4 Super Premium option is increasingly considered for large drives.

What IE4 Delivers at High Power

Under IEC 60034-30-1, IE4 Super Premium reduces losses noticeably compared with IE3. On a motor of 90 kW and above running thousands of hours a year, this difference appears as a constant saving on the energy bill and recovers the price gap over time.

Speed and Frame Options

High-kW IE4 motors are usually offered as 2-pole (3000 rpm) or 4-pole (1500 rpm). A cast iron frame provides durability under high thermal and mechanical load; IP55 protection and Class F insulation are standard in this segment.

Selecting by Application

A high-kW IE4 motor delivers the greatest value in compressor, fan and pump systems that run continuously at a high load ratio. For low running-hour applications, IE3 may be more balanced; the choice should be made on the load profile.
