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: main features
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.
Operational properties can thus be optimized by enhancing the mechanical stability (shape, components, friction coefficient) and electrical performances (voltage drop at contact, commutation ability, load capacity), reducing the sensitivity to environmental condition (protecting / polishing / lubricating action on the commutator skin), etc. The function of a good brush is further explained in our technical data sheet reference TDS‑01.
In addition, Mersen offers solutions for alerting on brush wear (indicator devices, linked to the brush or to the brush-holder), or, to go further, monitoring of operational parameters with our complete solution MERSEN Total Monitoring.
