Brush-holder for an electric machine such as, for example, an electric motor and/or a generator, - with a housing, having a brush support for supporting of at least one brush for electrically contacting of rotor windings of the machine, - wherein the housing is provided, on an installation side, with a recess for the accommodation of electric and/or electronic units, - wherein these units are inserted into the recess from the installation side, such that they can be electrically bonded from the installation side, - wherein a first such unit is formed by an EMC circuit for the improvement of electromagnetic compatibility, having a printed circuit board, on which at least one EMC unit is arranged, and having a plurality of mutually parallel and adjacently arranged EMC contacts, - wherein the recess has an EMC region for the fitting of the printed circuit board, - wherein a second such unit is constituted by an ECU component for the control of the machine, having a plurality of electrical ECU contacts in a mutually parallel and adjoining arrangement, - wherein at least one of the ECU contacts is electrically connected to one of the EMC contacts, - wherein the recess has an ECU region for the fitting of the ECU component, - wherein conductor rails (24, 25, 26, 27, 28) form a conductor frame, - wherein contact points of the conductor rails (24, 25, 26, 27, 28) are exposed at least in the brush support and in the recess, characterized in that - the housing is formed by plastic moulding, - the conductor frame is enclosed in the plastic moulding of the housing, - said contact points of the conductor rails (24, 25, 26, 27, 28) are not covered by the plastic in the brush support and in the recess, - the EMC contacts form an EMC contact rank on the printed circuit board, in which all the EMC contacts are configured in a mutually parallel and adjoining arrangement, - the ECU contacts form an ECU contact rank on the ECU component, in which all the ECU contacts are configured in a mutually parallel and adjoining arrangement, - the EMC contact rank and the ECU contact rank are arranged in opposition on a common plane, such that the EMC contacts run parallel to the ECU contacts, - all the EMC contacts are arranged in axial alignment opposite one of the ECU contacts respectively, and - in the EMC region each EMC contact and the respective opposite ECU contact are electrically connected to the respective conductor rail (24, 25, 26, 28) by means of soldered or welded joints, such that said conductor rail (24, 25, 26, 28) is electrically connected to said EMC contact and to said ECU contact. -
