Carbon brushes are essential components for conducting electrical current in various automotive systems. Typically made from carbon and other conductive materials, they are widely used in automotive generators and starters to transmit power and ensure the smooth operation of the engine. Their excellent conductivity and wear resistance make them indispensable in automotive electrical systems. They effectively collect current and maintain stable contact, thereby extending the lifespan of generators and starters. The quality of carbon brushes directly impacts the electrical performance and reliability of vehicles, making them crucial in automotive manufacturing and maintenance. Their role in ensuring efficient power transmission and electrical reliability underscores their significance in the automotive industry.
This series of carbon brushes is widely used in automobile starter motors, generators, wipers, window lift motors, seat motors, blower motors, oil pump motors, and other automotive electrical systems, as well as in DC vacuum cleaners, power tools, gardening tools, and more.
