Technical & development services for electric machines

ArcelorMittal supports motor and generator development with expert co-engineering, validated material data and manufacturing insight, helping design teams move from simulation to scalable production.

Co-engineering for electric machines

ArcelorMittal partners with motor and generator design teams to turn performance targets into manufacturable, industrial solutions. Our co-engineering approach combines deep expertise in electrical steels with hands-on understanding of electromagnetic design, mechanical constraints and large-scale production realities.

Our support includes:

  • Material selection support
    Identifying the right electrical steel grades based on performance, manufacturability and application needs.
  • Simulation support
    Providing reliable material data to enable accurate modelling and design optimisation.
  • Prototyping & validation
    Supporting prototype builds to test real-world performance and refine designs.
  • Industrialisation
    Helping scale from prototype to serial production with consistent quality and stable material behaviour.

Electrical machine design tools

As electrification accelerates across mobility, industry and energy systems, electric machine efficiency is under increasing pressure. Electrical steels play a critical role in determining these outcomes.

To support informed design decisions, ArcelorMittal provides tools and data that integrate electrical steel behaviour directly into development workflows

FAQs

Do you provide technical support during product development and qualification?

Yes. Our R&D teams and business development engineers support customers throughout product development, including trials, testing and material qualification. This helps ensure materials are validated and aligned with application requirements before industrialisation.

What ongoing technical support is available after project launch?

ArcelorMittal’s CTS (Customer Technical Support) teams provide continuous technical support since the very first stage of the project industrialisation and throughout the full lifecycle, helping reinforce customer capabilities and address evolving technical challenges, and also providing technical support during serial production.

Are digital services available to support collaboration and communication?

Significant investment has been made in digital services to streamline customer communication, data exchange and collaboration throughout development and production phases.

Do you offer tailor-made services for specific customer needs?

Yes. Services can be tailored to meet specific technical, manufacturing and supply-chain requirements, ensuring support is aligned with each customer’s application and project context.

Can I request samples of electrical steels?

Yes. You can request free samples across both our industrial and e-mobility product ranges. Available options include fully processed and semi-processed grades, as well as pole sheets and advanced solutions such as iCARe® Save, iCARe® Speed, iCARe® Torque and iCARe® 420 Save. Our team can also help guide sample selection to ensure the materials provided are aligned with your specific application and performance requirements.
