    Powering efficient motors and propulsion systems for eVTOL aircraft

    A revolution in flight

    Urban air mobility will transform travel with sustainable, fast, and convenient point-to-point transit. Electric motors bring the critical performance factors needed for air taxis and regional air mobility airplanes to reach broad adoption:

    • Quiet operation
    • High efficiency during high-torque, high-power takeoff, hover, and landing operations

    Materials propel performance

    Our industry-leading soft magnetic materials deliver the higher power and torque density required to make electric motors lighter and smaller. The best lamination stacks in aviation optimize motor and propulsion system performance:

    • Improved transient response
    • Cooler running temps for lower thermal stress
    • Direct drive reliability
    • Downsized battery pack for less weight
    • Longer range and endurance

    Powering urban air mobility

    Hybrid and full-electric aircraft

    The commercialization of electric aircraft will transform air travel, bringing more flexible, convenient, and clean transportation to people around the world:

    • Electric vertical takeoff and landing (eVTOL) aircraft
    • Hybrid and full-electric airplanes, and e-copters
    • Flying cars and hover bikes

    Optimizing power density

    In order for large-scale aircraft electrification to become a reality, electric aircraft will need high-output generators and motors with compact form factors. Our high-induction Hiperco® alloys give e-motor designers the materials they need to achieve:

    • High power density
    • High torque density
    • Reduced size and weight

    Stacking up performance

    Our advanced stator and rotor stack manufacturing capabilities enable the use of thin Hiperco® laminations, ideal for high-speed motors and generators:

    • Low core loss
    • Continuous power operation
    • Lower operating temperatures
