moteur CILS

Three-phase induction motors with cast iron IE4

75 to 200 kW


Developed to reduce drastically the energy consumption of the machines while maintaining maximum level of robustness and performance, the new Super Premium IE4 cast iron CILS series is integrating the global IMfinity® range.


The IMfinity® CILS is compliant to the ecodesign requirement of the EU 2009/125/EC directive and to the latest stage of the Commission Regulation UE 2019/1781 on induction electric motors starting July 2023. Indeed, from this date, electric motors with a power between 75 kW and 200 kW and covered by the regulation must have an energy efficiency level of IE4 minimum.
