Carbon Brush – High-Conductivity Brushes for Motors, Generators & Power Tools
Carbon Brushes are essential conductive components used in electric motors, generators, alternators, and power tools to deliver electrical current between stationary and rotating parts. Manufactured using high-grade carbon, graphite, and copper composites, these brushes ensure smooth current transfer, reduced friction, and stable motor performance. With excellent wear resistance and self-lubricating properties, carbon brushes are ideal for high-speed, heavy-load, and continuous operation applications.
