Abstract: The invention is related to a device for the noise suppression of small electric motors with a Cx capacitor to be installed between two connections (A1, A2) of the small electric motor as well as Cy capacitors installed between each of the connections (A1, A2) and a ground of the small electric motor, wherein the Cx capacitor and the Cy capacitors are combined in a disk-shaped component (1) which can be mounted on a housing cover (13) for the small electric motor or is integrated in the housing cover (13).

Abstract: A commutator arrangement for a small electric motor with a capacitor ring disk having several capacitor elements, wherein the capacitor ring disk is made of a dielectric first ring disk (RS) on whose upper side several sector-shaped electrode layers (6) are placed. Each of the electrode layers (6) are electrically conductively connected with a commutator segment (13). Counter electrodes of the capacitor elements are provided on an under side opposite the upper side. To improve the interference suppression features a single counter electrode layer (4), which underlies almost the entire surface of the electrode layer (6), is provided on the under side so that the counter electrodes of all capacitor elements have the same potential.
