ABSTRACT:
In a commutator formed by a plurality of commutator bars clamped between an annular shell and a clamping ring held together by studs, the life of the commutator may be extended significantly by imposing a resilient damper between the stud and the inside wall of a passage in the shell or ring, or both. The damper is spaced inwardly from the end of the stud, preferably by an amount approximately equal to one third of the length of the stud.
