The soft magnetic alloys to power electric aircraft

Torque-dense and power-dense lamination stacks bring urban air mobility to life

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

No other alloys stack up

Stator and rotor stacks made with our best-in-class Hiperco® and Hypocore® alloys are produced from decades of experience combined with investement in the latest equipment:

  • High-volume production
  • Up to industry specifications
  • Produced in state-of-the-art facilities

Our soft magnetic alloy experts bring you full-service support, from concept to production:

  • Prototyping
  • Design flexibility and optimization
  • Product ramp
  • Supply chain management

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

Hybrid Electric Aircraft and UAV

The success of aerospace electrification depends on higher motor and generator power density. Our high-induction soft magnetic alloys help achieve this goal and reduce battery weight thus increasing aircraft range.

Generator Systems and Auxiliary Power Units (APUs)

High-performance materials enable the design of smaller, electric machines without compromising on performance. Our materials enable the most power-dense, smallest, and lightest generators and APUs.

Our solutions are stress-tested in the real world. In 2009, US Airways flight 1549 was forced to emergency land on the Hudson River in New York City. Fortunately, the airplane’s auxiliary power unit was made of our high-performance Hiperco® 50, which enabled the pilot to maneuver the plane and all its passengers to safety.
