Abstract

PURPOSE: To improve an electrical and mechanical performance by cutting the tip of metal brush plate into a multiplicity of brushing parts such that the brush part contacting with the commutator is of wider width to make the slit width between the adjacent wider parts the specified width.
CONSTITUTION: The tip of the elastic metal brush plate 1 is cut into a multiplicity of brushing parts 2 like the teeth of comb, the part contacting with the commutator 3 is provided a wider surface 5, the slit width of which is made one to two times as much as the thickness of the brush plate 1. Also the brush teeth 2 except the wider contact surface 5 is provided a thinner width, the slit width between the adjacent teeth 2 is made three to four times as much as the thickness of the metal brush plate 1. Thus, an electrical and a mechanical wears between the commutator 3 and the contact part 5 of brush teeth 2 can be reduced to improve the performance.
