Investigation was performed to obtain data on performance of carbon brushes for traction motors of electric locomotives, to develop measuring method on commutation, and to examine brush materials through investigation of "filming action" on commutator surface; in special tests eccentricity of commutators, film distribution, roughness and damage of commutator surface, and brush wear were investigated.
