Three-phase asynchronous motors, efficiency class IE2 (high efficiency)
IE2 three-phase motors are a high-technology design developed for general applications. Compared with a standard efficiency motor, efficiency increases by roughly 5–10% depending on the type: a saving that becomes significant when there are many motors or high power ratings.

Efficiency classes and regulations
Standard IEC 60034-30-1 defines four classes: IE1 standard efficiency, IE2 high efficiency, IE3 premium efficiency, IE4 super premium efficiency.
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).
Our IE2 range covers 0.25 to 0.55 kW, where IE2 is the minimum class required. Contact us to check together the right class for your application.
