Abstract(in English) Many D.C motors are used for automotive electrical equipment. Particularly, a motor for a fuel pump has a distinctive feature that its commutation is carried out in gasoline. Our previous study reported that brush wear in gasoline was much more than that in air. And also carbon brushes were sometimes severely worn in negative polar. In this paper, the wear of carbon brushes under commutation arc in gasoline were investigated and compared with those of carbon-fiber brushes. In order to find the cause of severe wear, we examined with changing commutation current from 5-10A. As a result, an excessive carbon film is observed on the commutator surface when severe wear takes place.
