More electric is a platform being widely adopted by the current generation of aircraft. It offers
significant benefits in terms of fuel savings and flexibility of airframe design but relies on the
development of torque dense machines. This paper documents the development of an air-
cooled transverse flux machine for use in short-haul aircraft to improve on-ground
operational efficiency. If its potential is to be realized, this topology of the machine comes
with a new set of manufacturing challenges. Two competing machine layouts with different …

More-electric is a platform being widely adopted by the current generation of aircraft. It offers
significant benefits in terms of fuel savings and flexibility of airframe design, as well as
passenger comfort. The application of a motor drive to facilitate an aircraft's on-ground
operations has been well studied but as yet no solution has come to market for civil
aerospace. This paper documents a transverse flux machine topology for use in short-haul
aircraft, where current inefficiency can be bettered through use of an electrical machine …
