The AETP Program is a research platform funded by the New Zealand government, which is focused on developing technology to accelerate the electrification of large scale transport.For the last four years, a team of multidisciplinary researchers has been working together on a theme of fully superconducting machines, and aiming to develop a deep understanding of the key challenges and generate solutions that will be applicable in future motors, specifically in electric aviation applications.This presentation will outline some of the key work streams, and significant developments that have been achieved. These include
-Iron-free fully superconducting machine concept
-Cryogenic cooled rotor prototype
-REBCO saddle coils
-Additive manufactured cryogenic helium heat exchangers
-Superconducting power supply for field windings
-Stator conductor selection and AC loss management
-Stator cooling circuit design for liquid hydrogen cooling
We will present a summary of the work competed to date, as well as an outline of work in progress.
