Mersen offers a wide range of electrographitic brushes, particularly adapted to DC motors, of which world-renowned EG34D, 2192, EG8220 and AC137 brush grades.

Mersen's carbon brushes for DC motors are in use in different equipment in railways, energy, and process industries, such as: traction, crushers, rolling mills, winders...

Electrographitic grades are prepared from carbon powders and coke; they are then subjected to high temperature thermal treatments (>2500 °C) to transform the basic amorphous carbon into artificial graphite.

CARBON BRUSHES TO MEET YOUR REQUIREMENTS
Our research efforts result in brush materials which provide greater commutating ability, longer life, and reduced commutator maintenance. Mersen produces advanced brush grades for service conditions ranging from high loads to low loads, contaminated environments (chemicals, moisture, oil vapors), and other difficult operating conditions. A grade able to meet your requirements can thus be readily selected among our variety of materials - please refer to Mersen’s Technical Guide Technical Guide "Carbon brushes for motors and generators"

Mersen, as a reference supplier of electric motor manufacturers, also offers dedicated services of refurbishment, replacement of brushes and brush-holders, re-engineering and trainings.

DC MOTORS CARBON BRUSHES
Mersen is capable of supplying you with carbon brushes of various designs, including shapes, components and sizes, with a high quality of manufacturing, in particular cable connection by tamping. When required, we could adjust the design (grade, cable, top pad, wafer size…) to adapt the carbon brush specifically to your DC motor for its application.
