Friction and wear with a carbon-brush collector contact

  • Ragnar Holm
Chapter

Abstract

Any wear rate treated in this chapter is of the microtype; cf. classification Table (41.05). In spite of the small rate, the wear can be intolerable due to great distances of travel. Fairly subtle discriminations are important in practice. The present theory can not help much in this situation. Therefore, the exposition will be mainly confined to summarizing the empirical results obtained under fairly well defined conditions. Threading (grooving) and copper picking of brushes as well as blistering of the collector film will not be treated. Concerning these phenomenas we refer to R. Holm [37] p. 271, Shobert [7], and J. E. Thompson [2] where further references are noted.
