• The carbon brush of the generator is also called the electric brush, because its materials is "carbon", so it is often known as "carbon brush" The function of the carbon brush is to provide the external power supply (usually a DC excitation current) of the generator to the winding (excitation winding) of the rotor during the slip ring on the collector ring In this way, when the rotor rotates, the DC current flowing in will preserve flowing from one finish of the rotor, so that the generator rotates in a single route The carbon brush is connected with the flexibility supply to produce electrical calories for the rotor
