Abstract:
1. An electric motor assembly comprising: a stator assembly comprising: a rotor assembly comprising: a first end cap located adjacent to said first end of said stator stack and supporting a first end bearing for receiving said first end of said rotor shaft; a second end cap located adjacent to said second end of said stator stack and defining a second end cap bore concentrically aligned with said central rotor passage in an axial direction, and said second end cap including a first axially extending leg defining an annular space within said second end cap between said first axially extending leg and said second end cap bore; an overmold material extending through said stator slots and extending within and substantially filling said annular space within said second end cap; and an endbell formed separately from said second end cap and at least a portion of said endbell axially slidably positioned within said second end cap bore, a second end bearing located within said endbell for receiving said second end of said rotor shaft, wherein said endbell is slidably adjustable within said second end cap bore during positioning of said endbell into said second end cap thereby providing an adjustable final axial position for the endbell relative to said second end cap to compensate for variations in the axial position of said second end bearing relative to at least one of said stator assembly and said rotor assembly.
