What is a Carbon Motor Brush?

Understanding Carbon Brushes

Carbon motor brushes are essential components in electric motors that transmit electrical current between the stationary parts of the motor (stator) and the rotating part (rotor or armature). These brushes are made of a blend of carbon and graphite materials, providing both conductivity and lubricating properties. Over time, the brush wears down due to constant friction, but it is designed to be replaced easily without damaging the motor.

Why Carbon is Used

Carbon is the material of choice for motor brushes due to its excellent electrical conductivity and natural lubricating properties, which reduce wear on the commutator or slip rings. Additionally, carbon can withstand high temperatures and is resilient under the frictional forces typically encountered in electric motors, making it an ideal material for motor brushes like the 90930.
