The role of the carbon brush in the brush motor:

1. Change the direction of current (in the commutator machine, brush also play a directional role)

2. The external current (excitation current) on the carbon brush and added to the rotation of the rotor (input current)

3. The major axis (ground) leads to protection device for rotor grounding protection and measure the rotor voltage is positive and negative to ground

4. The static charges on the large shaft through the introduction of the earth (ground) carbon brush carbon brush (output current)
