This paper presents the design of a novel superconducting motor for electric aircraft. The motor is an axial flux, air-core, slotless, synchronous motor with a low-temperature superconducting rotor. There are two three phase liquid cooled copper stators. The superconducting rotor is cooled by an onboard reservoir of liquid helium, whose vapor is used to cool cryogenic eddy shields. The reservoir is sized for an 11 hour flight. The liquid helium is cooled at the airport and reused. G-10 fiberglass composite material is used for the spoke structure. The motor is sized to replace turboprop engines for regional passenger aircraft such as the Beechcraft 1900 and the Cessna Denali. It produces 1 MW of power and 4000 RPM and has a total mass of 100 kg which is superior to the comparable jet fueled engine, the General Electric Catalyst, which has a mass of 270 kg. It fits within the nacelle of the Beechcraft 1900.
