What is Carbon Brush? It's Functionality, Key Components & More

A carbon brush is an essential element of a motor that helps transmit electrical current from the spinning to the stationary components of the apparatus.
The main purpose of carbon brushes is to provide smooth electrical contact between moving and stationary parts. They ensure the smooth flow of electrical current by serving as a bridge, which is necessary to ensure the necessary smooth functioning across a variety of equipment applications.
Carbon brushes consist primarily of carbon or a carbon combination for conductivity, along with binders like resin for structural integrity. Metallic shunts facilitate current transfer, while terminal wires act as conduits for electrical flow within the assembly.
