Abstract of the Disclosure A generator having a stator and a rotor mounted for rotation relative to the stator, a generally cylindrical support structure for the stator either in the form of a housing or a support ring within the housing, said stator and support structure being formed of materials having substantially different thermal expansion rates and the stator having an outer surface engaging an inner surface of the support structure with an interference fit throughout the operating temperature range of the generator, and a plurality of longitudinal grooves formed in one of the surfaces to permit bending of said support structure in the area of said grooves when the generator is operating in the lower part of said temperature range. When the support structure is in the form of a ring, the housing also has a substantially different thermal expansion rate and the ring is supported relative to the housing by a plurality of integral legs associated with the grooves in a manner whereby the grooves each function as a deflecting arch for the adjacent leg whereby the legs maintain an interference fit with the housing throughout the operating range of the generator.
