Abstract
An electric machine incorporates a brush assembly that provides an audible warning when the brush in the brush assembly approaches the end of its useable length. The brush incorporates a device incorporated into the brush or a brush design which cooperates with the brush holder to generate the noise. The noise provides a warning to the user of the electric machine that the useable length of the brush material is near.
