Abstract
A process for producing a brush for an electric motor having predetermined final dimensions and including a wearing block and a connecting braid. The brush is produced by preparing at least one mixture including a conductive graphite powder in the form of solid particles of a mean thickness less than 25 .mu.m and a mean shape factor greater than 5, encased with a distillation binder. The mixture is molded together with the connecting braid in a mold to form a crude brush of the final dimensions and the crude brush is baked.
