ABSTRACT:
A stator core support structure and an assembly of a stator core in a core support structure, both characterized by having a plurality of stress-relief devices that are mounted at selected areas of high radial rigidity on the core support structure to transmit a predetermined compressive force from the support structure to a stator core mounted in it with an interference fit, thereby to secure the stator core in a predetermined geometric configuration. The method of the invention includes the steps of mounting a plurality of stress-relief devices at selected points between a stator core and a support structure surrounding it, and loading each of said devices to transmit compressive forces to said points of the stator to secure it in a desired geometric configuration within the support structure.
