Carbon Brushes for Electric Motors

Tailor-made carbon brushes for precise requirements

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

Typical requirements for carbon brushes:

High current or low signal transmission with specifically selected resistance
Low wear and long service life, even in challenging atmospheres
Thermal stability under high loads
Adaptation to individual motor parameters
Compliance with specific environmental standards (e.g., hygiene areas)

This ensures maximum efficiency in motor operation – reliably and sustainably.

Materials & Technologies

What sets our motor carbon brushes apart

Our motor carbon brushes are based on high-quality materials such as electrographite, metal graphite, or hard carbon. Each composition is precisely matched to the mechanical and electrical requirements of your application. The result: solutions with optimal current transmission, minimal wear, and high temperature resistance – even under extreme conditions.

Regardless of whether a direct current (DC) or alternating current (AC) motor is used, the choice of material and geometry is crucial. In aggressive environments – such as in the chemical industry – special impregnations and finely tuned shapes significantly enhance performance.

Carbon brushes for electric motors in practice

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

Industry-specific requirements

Chemical Industry: Corrosive media, temperature fluctuations, and vibrations require durable, impregnated special materials.
Textile, Paper & Printing Industry: Dust, humidity, and fluctuating loads demand long-term stability.
Food Industry: Hygienically critical production environments require carbon brushes that meet sector-specific standards, are cleaning-resistant, and process-stable.
Crane Systems & Warehousing: Start-stop loads, dynamic load changes, and varying ambient temperatures require resilient materials with constant current conduction in continuous operation.
Power Tools & Household Appliances: High speeds, vibrations, and mass production demand reproducible quality at optimal cost.
Micromotors & Wire Industry: Compact designs, tight tolerances, and minimal wear are crucial for precise results.
