ABSTRACT:
A compliant clamp (20) for a power generator and associated methods are provided (see FIG. 5). The clamp (20) preferably includes an end plate (18) mounted to an end of a generator stator core (10) and a core attaching member (15) connected to the generator stator core (10) and positioned to connect the generator stator core (10) to a frame (12). The core attaching member (15) preferably has at least an end portion (22) extending outwardly from the end plate (18). At least one spring member (25) is preferably mounted to the end portion (22) of the core attaching member (15) for springingly biasing the end plate (18) inwardly toward the generator core (10). The clamp (20) further includes at least one retaining member (23) mounted to the end portion (22) of the core attaching member (15) for retaining the spring member (25) on the end portion (22) of the core attaching member (15), a current shunt member (30) mounted to the end portion (22) of the core attaching member (15), having at least one portion abuttingly contacting the end plate (18), and having another portion abuttingly contacting the retaining member (23) to thereby provide a current shunt path from the retaining member (23) to the end plate (18), and at least one insulating member (26) mounted to the end portion (22) of the core attaching member (15) and positioned between the current shunt member (30) and the at least one spring member (25).
