Motor Brushes
Motor brushes are an essential component of electric motors that help to transmit electrical current to the motor's rotating armature. They consist of two parts: a conductive carbon block and a metal spring. As the motor spins, the brushes make contact with the armature, allowing current to flow through the motor. Over time, the brushes can wear down and need to be replaced to maintain the motor's performance. Motor brushes are commonly used in various applications, including power tools, household appliances, and automotive systems.
