Abstract

A rotor assembly for an electrical machine includes two pole pieces with intermeshing pole fingers. Disposed between the pole pieces is a silencer assembly with silencer portions at least partially filling the gaps between adjacent pairs of intermeshed pole fingers. The silencer portions have projections which cooperate with lateral surfaces of the pole fingers to limit outward radial movement of the silencer portions.
