Abstract:
An electric propulsion assembly for an electric aircraft propulsor including an integrated stator assembly including a mandrel having an outer cylindrical surface, an inner cylindrical surface, an upper edge, and a lower edge, the mandrel includes a plurality of electrically insulating guide walls disposed on at least a portion of the outer cylindrical surface and at least a portion of the inner cylindrical surface, wherein the electrically insulating guide wall forms a path across the outer and inner cylindrical surfaces. Assembly includes a plurality of copper windings wound upon the mandrel, electrically insulating epoxy, wherein the epoxy envelops at least a portion of the plurality of copper windings, a first cylindrical surface facing the inner cylindrical surface including a permanent magnet array, a second cylindrical surface facing the outer cylindrical surface including a back iron and a void disposed between the first cylindrical surface and the second cylindrical surface.
