ABSTRACT:
The present invention provides a method for producing a stator assembly. The method initially includes providing an assembly mandrel having a generally cylindrical hub and a generally annular base circumscribing a terminal end portion of the hub. A first end ring and a stator shell are installed around the mandrel hub and onto the mandrel base. Thereafter, a plurality of poles are disposed on top of the first end ring and in a generally cylindrical pattern between the stator shell and the mandrel hub. A second end ring is disposed around the mandrel hub and on top of the plurality of poles. A plurality of stator shell tabs may then be bent in a radially inward direction to axially retain the first and second end rings.
