Super premium efficiency three-phase motors IE4

Three-phase asynchronous motors, efficiency class IE4 (super premium efficiency)

IE4 is the highest efficiency class defined by IEC 60034-30-1 for three-phase asynchronous motors. It further reduces losses compared with IE3 and is the most cost-effective choice for plants running many hours a year, where lower consumption quickly pays back the higher initial cost.

When an IE4 motor pays off

  • continuous duty and many operating hours per year
  • medium to high power ratings, where every efficiency point is worth many kWh
  • pumps, fans and compressors
  • 2-, 4- and 6-pole motors from 75 to 200 kW, for which IE4 is mandatory in Europe

European regulations

Since 1 July 2021, EU Regulation 2019/1781 requires at least efficiency class IE3 in Europe for three-phase asynchronous motors with 2, 4, 6 and 8 poles from 0.75 to 1000 kW, and at least IE2 from 0.12 to 0.75 kW. Since 1 July 2023, 2-, 4- and 6-pole motors from 75 to 200 kW must be class IE4 (brake motors and motors for explosive atmospheres excluded).

Frame sizes, power ratings, poles and mounting are defined according to the application: send us your data and we will propose the right motor.
