About this technology
Overview
Innovators at the NASA Glenn Research Center have designed a High Efficiency Megawatt Motor (HEMM), a wound-field partially superconducting machine. The HEMM implements a combination of superconducting and non-superconducting elements, along with an integrated cryocooler, to achieve some of the benefits of a superconducting motor without the need for an external cryogenic system. This work is sponsored by the NASA Advanced Air Transportation Technologies project and the Hybrid Gas Electric subproject for use as an electrified aircraft propulsion (EAP) system. Electrification of propulsion has the potential to revolutionize the aviation industry by improving fuel efficiency, reducing emissions, and decreasing dependency on carbon-based fuels. While the HEMM is designed for future hybrid electric aircraft, the technology could be broadly applied to transportation markets including electric trains, hybrid cars, and turboelectric ships.
