1. A stator for an aircraft electric motor comprising:
a cantilever structure having a supported end and an unsupported end, wherein the cantilever structure includes an inlet support manifold and an outlet support manifold arranged at the supported end and a plurality of cooling plates extending from the inlet support manifold and the outlet support manifold to the unsupported end;
a plurality of coils arranged between and in thermal contact with the cooling plates;
a core passing through the plurality of coils and the plurality of cooling plates; and
a plurality of magnetic teeth wherein the cooling plates define gaps between adjacent cooling plates and each gap includes a coil of the plurality of coils and a magnetic tooth of the plurality of magnetic teeth,
wherein each cooling plate defines a cooling channel that fluidly couples the inlet support manifold and the outlet support manifold, and
wherein the coils and the core are structurally supported by the plurality of cooling plates in a cantilevered manner at the supported end.
