ABSTRACT:
The invention relates to a collector machine, in particular an electric motor, having a rotor, rotatably supported in a housing and having an armature winding and a collector. The collector for electrically contacting the armature winding cooperates with at least two brushes resting slidingly on the collector, which are each displaceably guided counter to an initial tension in a respective quiver provided for each brush on a brush carrier plate. In accordance with the improvement according to the invention, at least one contact element, which is part of an associated quiver and for one pole of the electrical contacting establishes an electrically conductive contact with the housing.
