Electrical steels are specialty steels tailored to produce certain magnetic properties - strips of electrical steel are stacked (laminations) to form electric motor stators and rotors. ArcelorMittal’s iCARe portfolio was created to help carmakers deliver lower emissions and improved fuel consumption for hybrid vehicles, or longer range for pure EVs. The iCARe steels promise to deliver increased power density from electric motors, helping to reduce the size and weight of a vehicle via enhanced energy efficiency.
