- Motors and/or generators (Electric machines) are needed on all electrified aircraft.
- NASA is sponsoring or performing work to achieve power densities 2-3 times the state of the art for machines in the MW or larger class.
- Three major machine types are being developed: permanent magnet, induction, and wound field
power rating, MW
