Abstract
The invention relates to a carbon brush and a method for producing a carbon brush for electrically contacting a contact structure, in particular a commutator or a collector ring of an electric machine, moved with respect to the carbon brush, a brush body of the carbon brush being realized by pressing and hardening a material blend, the material blend being obtained by blending a graphite powder with a hardenable resin and an additive, wherein graphene is used as the additive.
Claims14
A method for producing a carbon brush for electrically contacting a contact structure of an electric machine, moved with respect to the carbon brush, the method comprising:
- forming a brush body of the carbon brush being obtained by pressing and hardening a material blend, the material blend being obtained by blending a graphite powder with a hardenable resin and an additive, characterized in that graphene is used as the additive.
A carbon brush for electrically contacting a contact structure of an electric machine, moved with respect to the carbon brush, the carbon brush being made of a brush body comprising a hardened material blend made of graphite powder having a hardened resin and a particle-shaped additive, characterized in that the additive is graphene.
