Abstract:
An electric machine including a stator having a sealed inner diameter, comprising:a stator including a plurality of circumferentially-spaced stator segment assemblies each including: a stator segment core; an endcap that is attached to said stator segment core; and winding wire that is wound around said endcap and said stator segment core, wherein said endcap provides first and second axial mating surfaces; and a rotor that rotates relative to said stator and that defines an airgap between an outer diameter of said rotor and said inner diameter of said stator, wherein said first axial mating surface of one stator segment assembly mates with said second axial mating surface of an adjacent stator segment assembly to provide axial seals between said stator segment assemblies and to prevent the entry of debris into said airgap.
