Wear of current collectors (electrical brushes) is a major cause of             failure in motors, further, resultant down time for repair has a                serious impact on productivity.  The objective of this effort is to             provide an improved theoretical model of high current density brush             physics that includes both dynamic and thermoelastic effects.                   Specifically, the effects of bulk variables such as current, rotor              speed and geometry, contact force, and others on the formation of               slowly moving hot spots in the brush will be  investigated.  With               better understanding of brush physics, the model should lead to                 improved brushdesign.
