ABSTRACT:
A stack of stator core laminations are compressed between a pair of resilient end flanges that are flexed into a dished configuration and secured in a pre-determined spaced-apart relationship by being welded to a plurality of longitudinal ribs disposed around the periphery of the stator laminations. Special tools and welding techniques are used during the manufacture of the core assembly to cause the dished flanges to continuously apply a pre-determined compressive force to the stacked laminations after the core assembly is completed.
