Metal-graphite brushes for direct current rotating electric machines

Lampar, specializing in the production of carbon brushes of any type and dimension for electrical machines, manufactures and sells bakelite-graphite brushes for direct current rotating electric machines with low voltage.

Metal-graphite can be obtained from graphite and carbons mixed with dust of copper and other metals, it has a high conductivity and low electric contact resistance; current density is much higher then of pure carbon one.
