The carbon brush is an important part that acts as a conduction role and rectification by touching the surface of a commutator or a slip ring of a rotating machine such as an electronic commutator.
It is produced by powder metallurgy process mainly made of graphite.
Metallic Graphite: Wound Induction Motor, Low Voltage Small DC
Resin-bonded graphite: Small AC commutator motor
Carbon graphite: Small DC, AC motor
Electric graphite: DC generator, turbine generator, synchronous motor
