ABSTRACT:
A packaged stator core assembly and a method of making such an assembly and mounting it on a housing frame. Arcuately spaced tension ribs secure two annular clamping flanges in compression against opposite ends of a stack of stator laminations. Torque ribs, each having an angular cross-section and a key portion located substantially at its shear center, are welded between the clamping flanges to hold the ribs in engagement with positioning slots or tabs on the outer periphery of the stacked laminations. The lines of reaction torque force from the laminations to the ribs pass essentially through the shear centers of each rib. In the method of the invention the ribs are welded to the clamping flanges and the stator core package is mounted in a housing frame by welding only the flanges to the frame.
