Three-phase motors IE1

Three-phase asynchronous motors, IE1 series

Our range of IE1 three-phase asynchronous electric motors is the ideal choice for industrial automation that demands reliability and flexibility. Designed to IEC standards, these motors combine robust construction with optimised energy management, covering a wide range of power ratings and mechanical applications.

Why choose our motors

Inverter-ready: insulated phases on all frame sizes allow use with inverters without discharge risks.
Full protection: rotors are tropicalised with moisture-resistant varnish that protects the winding from humidity.
Flexible connection: 230/400 V 50 Hz from IEC 56 to 132, 400/690 V 50 Hz for larger frames (160–315).

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).

IE1 motors are therefore used in applications excluded from the regulation or outside the European Union. Contact us to check together the right class for your application.
