Brushes with High Current and High Sliding Speeds.
Abstract
Experimental results in the literature indicate that electric brushes may deform, leading to point contact with the slip ring at high current levels. The present work provides theoretical support for these observations and a quantative statement showing how operating variables influence this behavior. The analysis is restricted to a two dimensional model of the brush, with isotropic and constant material properties. The most unexpected result is that, for steady current flow, cooling of the exterior of the brush increases the tendency to deform unfavorably. (Author)
