Cryo-Electric planes are being envisaged for the 2030’s. A key technological hurdle for realizing this is the availability of flight-weight motors, generators, and power distribution systems. Historically superconducting industrial and marine machines have been demonstrated – but not at the required flight power and volume densities. Developments for compact lightweight highly efficient...
Electrified aircraft are being developed to address climate change by reducing the fuel burn and emissions of aircraft. The large majority of aviation’s impact on the environment is caused by large transport aircraft, or those that can carry about 150+ passengers. At this scale, MW-class electrified propulsion systems are required. To achieve a net fuel burn and/or emissions benefit after...

Abstract - The increasing demand for high-power density electric motors in transportation industries opens a new research opportunity to develop motor topologies with less weight and higher efficiency. In particular, electric aircraft applications require very high power density motors. And increases of efficiency are desired for transportation, to reduce system impacts of high heat loads and...
There is growing interest to use superconductors for actuator applications. High-field superconducting electromagnets enable a much higher performance. DC-excited stator coils in such systems are subjected to time-varying magnetic fields of up to several hundred mT, leading to significant AC loss. Inherently stable no-insulation coils make motion systems more reliable, but come at the cost of...
