Custom-Engineered Carbon Brushes for Demanding Requirements

Each application places specific demands on carbon brushes – from current density and operating conditions to contact materials and mechanical stress. Our solutions are precisely adapted to your operating conditions. With state-of-the-art manufacturing technologies, we ensure consistent quality and optimal performance – even for complex technical requirements.

Typical requirements for carbon brushes:

Load change resistance
Low wear of brushes and counter material
Adaptation to individual motor parameters
Secure current transmission

This results in maximum safety in motor operation – reliable and long-lasting.

Materials & Technologies

What sets our motor carbon brushes apart

For our carbon brushes, we use premium materials such as electrographite, metal graphite, or resin-bonded graphite. Each composition is specifically adapted to the mechanical and electrical demands of your application. This results in solutions offering optimal current transmission, low abrasion, and high resistance to load changes – even under extreme conditions.

Regardless of whether a DC (direct current) or AC (alternating current) motor is used, material selection and design are critical. In aggressive environments – such as the chemical industry – special impregnations and precisely matched forms significantly enhance performance.

Carbon brushes for electric motors in practice

Our carbon brushes for electric motors are used across numerous industries – from highly sensitive industrial sectors to large-scale consumer applications. Requirements vary depending on the environment, load, and speed.

Industry-specific requirements:

Chemical industry: Corrosive media and temperature fluctuations require durable, impregnated specialty materials.
Textile, paper & printing industry: Dust, chemically contaminated environments, humidity, and fluctuating loads demand long-term material stability.
Cranes: Start-stop stress, dynamic load changes, and varying ambient temperatures require robust materials and reliable current transfer.
Power tools & household appliances: High rotational speeds, vibrations, and strict EMC requirements call for specially adapted material and design combinations.
Steel & cement industry: Dynamic load changes, different climatic and extreme environmental conditions, as well as mechanical stress.
Micromotors: Compact dimensions, tight tolerances, and minimal abrasion are critical for precise results.

As diverse as the applications may be – our carbon brushes deliver consistent quality.
