Negative temperature co-efficient. The carbon brush is having negative temperature co-efficient.
Shape adopting. ...
Self lubricating.
Simply put, carbon brushes reduce the damage to the motor. The block of carbon, referred to as a brush, carries a current back and forth from the stationary parts of a motor to the moving parts. These brushes also help transmit electricity from outside the motor to the mid part, or spinning area of the motor.
Although the first brushes were made of copper, carbon eventually became the preferred motor brush material because of its high contact resistance, low friction, and ability to resist arcing.
