The technology is particularly well-suited for aerospace propulsion and actuation systems, where every gram saved contributes to lower fuel consumption and increased payload capacity.

Description

Lightweight electrical winding material for high-performance electric motors, offering a significant reduction in motor weight without compromising efficiency or mechanical robustness. The technology is particularly well-suited for aerospace propulsion and actuation systems, where every gram saved contributes to lower fuel consumption and increased payload capacity.

Advantages

  • Up to 25% lighter than reference copper windings, enabling more compact and efficient motor designs.
  • Comparable electrical efficiency, maintaining performance across standard operating ranges.
  • Superior thermal and mechanical stability, supporting operation under demanding aerospace conditions.
  • Reduced system-level complexity, eliminating the need for auxiliary cooling or weight compensation.
  • Sustainability benefit through lower material mass and potential recyclability of carbon-based conductors.
