Patent ID: 7723895

Claim:
Rotating electric machine apparatus including concentric rotor and stator assemblies comprising: an end plate cooperates during assembly of the electric machine apparatus to prevent undesirable contact between the rotor assembly and the stator assembly; said endplate defines an assembly guide ring having an outer peripheral wall and a protuberance formed radially outwardly from said outer peripheral wall, wherein the protuberance is circumferentially continuous and forms a uniform spacer between the rotor assembly and the stator assembly; wherein the stator assembly comprises: a stator unit having opposing ends and an outer cylindrical peripheral wall with an outer wall diameter; and said end plate defining said assembly guide ring being located at one of the opposing ends of the stator unit and said protuberance of the assembly guide ring having an outer ring diameter larger than the outer wall diameter of the outer cylindrical peripheral wall of the stator unit.
