THE FUNCTION OF CARBON BRUSHES:

1. Apply External Current (Excitation Current) to the Rotating Rotor Through the Carbon Brush (Input Current);

2. Introduce the Static Charge on the Main Shaft Through the Carbon Brush to the Ground (Grounding Carbon Brush) (Output Current);

3. Change the Direction of the Current (in the Commutator Motor, the Brush Also Plays a Commutation Role);

4. Connect the Main Shaft (Ground) to the Protection Device for Rotor Grounding Protection and Measure the Positive and Negative Voltage of the Rotor to Ground.

HIGH QUALITY TO BE TRUSTWORTHY:

1. Strong Conductivity: Motor Carbon Brushes Are a Highly Conductive Material That Can Effectively Transmit Current. When the Motor Is Running, the Carbon Brush Needs to Come into Contact with the Rotating Shaft to Convert Electrical Energy into Mechanical Energy Through Friction.

2. Low Friction: the Carbon Brush Has a Smooth Surface and Low Friction, Therefore It Has a Lower Wear Rate During Motor Operation. This Feature Allows the Motor to Operate for a Long Time Without Replacing the Carbon Brushes.

3. Long Lifespan: the Lifespan of Motor Carbon Brushes Is Generally Relatively Long and Can Withstand High Working Pressure and Temperature, so They Are Widely Used in Various Types of Electric Mechanical Equipment.

4. High Maintainability: Compared to Traditional Metal Brushes, Motor Carbon Brushes Have the Characteristics of Being Detachable and Replaceable, Facilitating Maintenance and Replacement, and Reducing Equipment Repair Costs.
