Carbon Brushes for Generators

High-Performance Carbon Brushes for Generators of All Sizes

Generators operate under fluctuating load profiles and must function reliably even under extreme climate conditions. The carbon brushes used must withstand these stresses over the long term – while ensuring minimal wear on brushes and slip rings.

Additional challenges such as temperature variations, current fluctuations, vibrations, and long-term operation place high demands on material selection and design. Our generator brushes are precisely tailored to meet these challenges – including application-specific metal content for the required current density.

Typical requirements for generator brushes:

Reliable performance under varying climate conditions
Long-term current transmission
Low power loss under high load
Extended service life
Slip ring-friendly operation
Reliable contact under vibration, load shifts, and standby operation

This is how we ensure maximum operational safety – for years to come.

Materials & Technologies

Materials, Designs, and Technologies at a Glance

The right material selection is key to the efficiency and service life of generator carbon brushes. Depending on the application, materials such as metal graphite or electrographite are used. These materials differ in conductivity, density, friction coefficient, and load capacity – whether for continuous operation, infrequent use, or extreme current peaks.

Our custom designs enable a wide range of features, such as vibration damping, on-load brush replacement, wear indication, retrofit compatibility, and application-specific conductor cross-sections.

Carbon Brushes in Generators for Energy & Industry

Schunk carbon brushes for generators are used worldwide in a variety of energy and industrial applications. Depending on location and load, the demands vary – from high current density to challenging environmental conditions.

Our application areas:

Power plants (coal, gas, hydro, biomass): Long-term operation, high load variation, low-maintenance design
Wind turbines (onshore & offshore): Temperature fluctuations, humidity, salty air, compact designs, vibration resistance
Emergency generators & mobile units: Quick start-up times, minimal standstill corrosion
Industrial systems & flywheel storage units: Harsh conditions involving oil, dust, heat, and high torque

Our solutions ensure consistent performance – from scheduled grid operation to unplanned emergency power supply.
