What Is Carbon Brush / Motor Carbon Brush

Carbon Brush, also known as Motor Carbon Brush, is a core conductive sliding component widely used in brushed motors and rotating electrical equipment. Made of high-purity graphite or composite graphite materials, it installs on motor stators and maintains stable contact with rotating commutators, realizing safe and continuous current transmission and commutation switching. As a vulnerable and essential motor part, it directly determines the operating stability, noise level and service life of electrical equipment.

Main Material Types of Carbon Brush & Motor Carbon Brush

Carbon brushes are mainly divided into four mainstream materials to adapt to different working conditions. Natural graphite brushes feature low noise and small sparks, ideal for light-load household appliances. Electro graphite brushes are the most universal industrial type, with excellent wear resistance and stable commutation performance for conventional AC and DC motors. Metal graphite brushes mixed with copper or silver powder boast high conductivity and high temperature resistance, suitable for high-current heavy-duty equipment. Resin-bonded carbon brushes have strong mechanical strength and vibration resistance, applicable for harsh working environments such as mining and engineering machinery.
