eVTOL Motors Face Unique Challenges Compared to Electric Vehicle Motors

Published on April 27, 2026

Electric vehicles have long been synonymous with sustainable transportation. Their development centers around efficiency and cost-effectiveness. However, the rise of electric vertical take-off and landing (eVTOL) aircraft is pushing the boundaries of traditional electric motor design.

Jon Wagner, a former Tesla engineer, now leads power train development at Jo. He outlines fundamental differences in priorities between eVTOL and conventional electric vehicle motors. In aviation, cost considerations take a back seat to weight and efficiency, pushing manufacturers to invest more in components that enhance performance and safety.

Safety standards in aviation necessitate a focus on redundancy that is often absent in electric vehicles. While both industries share similar motor technologies, eVTOL designs incorporate multiple backup systems to ensure continued flight in emergencies. The lack of a safe stopping point in the sky fundamentally alters the engineering approach taken .

The implications of this shift are significant. As the eVTOL industry matures, it could redefine manufacturing processes and introduce novel materials, such as high-cost cobalt-iron alloys. As Wagner emphasizes, the journey toward widespread eVTOL adoption will require a blend of innovation and patience, marking a substantial evolution in transportation technology.
