Abstract:

Recent work at the University of Virginia has shown that metal fiber electrical brushes with fiber diameters as low as 5 μ m can be superior to the best available commercial monolithic brushes in three important respects: lower electrical loss at the interface between a brush and a rotor, high current capacity, and ability to run stably at much lower loads. In this project, even thinner fibers were used in gold and platinum brushes, and results showed that better conductivity and performance was observed, but that performance fell short of theoretical expectations when tested.
