Next-generation hybrid military vehicles, hybrid electric aircrafts and emerging urban air mobility platforms will require new integrated propulsion systems. To increase the fuel efficiency and flight times for these applications, the volume, weight and power density of the electric motors need to be considered. Adoption of Silicon-carbide (SiC) technologies will help achieve high power density, high temperature operation, high efficiencies and smaller drive size. Calnetix Technologies’ Defense & Aerospace division is developing lightweight air-or liquid-cooled high-speed electric motors along with SiC-based drives that will significantly reduce the system mass and subsequently boost fuel efficiency and flight times.
