Aenterprise provides top-quality carbon brushes engineered to improve the performance and extend the lifespan of electric motors, generators, and other rotating equipment. Made from premium materials, our brushes ensure excellent conductivity, minimize wear, and help keep maintenance to a minimum.

Manufactured using high-grade carbon and graphite materials, our brushes provide excellent electrical conductivity, reduce friction, and minimize wear on commutators and slip rings. This not only enhances operational reliability but also cuts down on maintenance costs and downtime. Designed to perform under demanding conditions, our carbon brushes are ideal for use in automotive systems, industrial motors, power tools, rail traction motors, and more.

Composition and Material Types

  • Metal Graphite: Incorporates metals like copper for improved conductivity and heat dissipation.
  • Silver Graphite: Used for high conductivity and low contact resistance.
  • Pure Graphite: Offers high resistance and is suitable for low-load applications.
  • Resin Graphite: Provides enhanced mechanical strength.
  • Electrographite: High-purity graphite for demanding electrical environments
