Carbon brushes for train traction motors are important components in the traction motors of trains. Here is an introduction to the product:
Material and Structure
Material: The main materials are electrographite, impregnated graphite, and metal (copper, silver) graphite. Electrographite has good electrical conductivity and high-temperature resistance; impregnated graphite is treated by impregnation to enhance its lubrication and wear resistance; metal graphite, containing metal components, has better electrical conductivity and mechanical strength.
Structure: It usually consists of brush filaments, brush braids, and brush holders. The brush filaments are the key parts of the carbon brush that contact the commutator, and their material and performance directly affect the performance of the carbon brush; the brush braid is used to connect the brush filaments and the external circuit to ensure the stable transmission of electric current; the brush holder serves to fix and support the carbon brush, enabling it to stably contact the commutator.

Product Feature
1.Good Electrical Conductivity: As a key component for current transmission, the carbon brushes for train traction motors have excellent electrical conductivity, ensuring the smooth and efficient conduction of electric current between the fixed and rotating parts of the motor, thereby ensuring the normal operation of the motor.
2.Excellent Commutation Performance: In DC motors, the carbon brush cooperates with the commutator to switch the direction of the current continuously during the rotation of the rotor, driving the motor to keep running. Some carbon brushes, such as Morgan's ME778, have good commutation performance and are widely used in electric locomotive and light rail traction motors.
3.Strong Wear Resistance: During the operation of the train traction motor, there is continuous friction between the carbon brush and the commutator. The carbon brush has high wear resistance, which can maintain stable performance in long-term friction, reduce wear and replacement frequency, and reduce maintenance costs.
4.Good Self-lubrication: Carbon materials themselves have good self-lubrication properties. A lubricating film can be formed during the friction process, reducing the friction resistance and further reducing the wear between the commutator, improving the operating efficiency of the motor.
5.Strong High-temperature Resistance: The motor generates a lot of heat during operation. The high-temperature resistance of the carbon brush enables it to work normally in a high-temperature environment, ensuring the stable operation of the motor.
