Abstract

본 발명은 자동차용 소형모터외 카본브러쉬에 관한 것으로, 정류자에 전류공급 및 차단을 하게되는 카본브러쉬를 주성분인 흑연(C)에, 소정의 직경과 함량비로 동(CU), 이황화몰리브덴(MoS2), 납(pb)을 조성하되, 상기 흑연(C)의 입자직경범위만을 소정범위로 조정하여 비저항 및 마찰계수를 낮추어줌으로써 출력특성 및 습동특성을 향상시킬 수 있도록 한 것임.The present invention relates to a carbon brush other than a small motor for automobiles. The carbon brush, which supplies and cuts current to the commutator, is composed of graphite (C) as a main component, copper (CU) and molybdenum disulfide (MoS 2 ) in a predetermined diameter and content ratio. ), To form lead (pb), but by adjusting only the particle diameter range of the graphite (C) to a predetermined range to lower the specific resistance and friction coefficient to improve the output characteristics and sliding characteristics.
