The important role of brush DC motor armature current with transmission and transform the cur-rent direction. Suitable brush relates to many factors restrict the problem, there is not a set of scientific selec-tion method. The brush selection, this paper summarizes two aspects. One is the main factor in determining the brush contact resistance and voltage drop, illustrated by a factor of six. Two is the correct selection of DC mo-tor brush should pay attention to aspects, summed up the six aspects.
