<p>The present invention provides an encapsulated stator assembly comprising: (a) a stator having a stator core and a stator end region; and (b) a ceramic bore tube defining a surface of the stator core; wherein the stator end region is disposed adjacent to the stator core, and wherein the stator end region comprises a plurality of stator armature end-windings, and wherein the stator end region comprises an inwardly-facing stator wall, and wherein the ceramic bore tube and the inwardly-facing stator wall define an interior volume configured to accommodate a rotor, said inwardly-facing stator wall having an inner surface and an outer surface, at least a portion of said inner surface comprising a barrier layer of a conductive metal selected from the group consisting of copper, silver and aluminum, said inwardly-facing stator wall comprising a corrosion resistant metal. Also provided are motors comprising the novel encapsulated stator assemblies.
