The characteristics of carbon and graphite used in carbon brushes can generally be judged from the items of "electrical resistivity," "hardness," "bending strength," and "bulk density." In the case of metal graphite, the metal content is also noted in addition to the above items. All data are averages. The testing methods and equipment generally conform to IEC60413. These values can vary significantly due to various environmental factors and operating conditions. Therefore, based on experience, we have established a general range for the values of the two items and compiled them into a table by category. Please refer to the PDF document below for confirmation. *For more details, please refer to the PDF document or feel free to contact us.*

Schunk's grounding system effectively protects bearings from damage by directly discharging the capacitive discharge current generated from the rotor of the drive motor's shaft. It also minimizes noise emitted from the motor shaft.

Electrostatic discharge from the generator causes stray currents to occur in the shaft. If this current is not diverted, it can cause significant damage to the bearings; however, our high-quality two-layer carbon brushes handle it safely and reliably. Rollers and bearings are protected, avoiding costly repairs and system downtime. The advantages include: - Individually tailored materials for two-layer carbon brushes - High reliability and efficiency - Excellent protection for bearings and gearboxes

The rotating propeller shaft of the ship is electrically insulated from the hull by the use of a lubricating oil film within metal bearings or non-metal bearing materials. A potential is formed between the propeller and the hull, resulting in a current that returns to the hull through the gearbox. In this situation, a large current flows through the bearings and gearbox, causing these components to suffer from pitting and damaging the bearings, gearbox, and shaft. Schunk's grounding system prevents these phenomena.

Electromagnetic static electricity, system harmonics, and modern power electronics used in combination with motors and generators can potentially cause unwanted high-frequency currents. These currents often wander in search of a path to ground and circulate throughout the system. The problems caused by these currents can lead to issues such as: ● Electromigration of components like bearings and shafts ● System communication noise ● Damage to large-scale system electrical circuits ● Ground loop feedback Schunk Carbon's grounding solutions will solve your problems!
