ABSTRACT:
Indicators of incremental brush wear are disclosed. Versions of the indicators may comprise signal wire assemblies embedded in brushes so that they continuously contact rotating components of electrical machines. Each such wire assembly typically is chosen so that its nominal electrical resistance differs from that of its corresponding brush, while its mechanical properties remain similar to those of the brush.
