Carbon brushes for DC motors in traction and process equipment
Mersen offers a wide range of electrographitic brushes, particularly adapted to DC motors, of which world-renowned EG34D and EG8220 brush grades.
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.
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, environments contaminated (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 "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.
