Abstract
The invention relates to a brush-holding device for electric motors comprising carbon brushes, a conductive stamped grid as a printed circuit board, a base to which the printed circuit board is attached and components for monitoring temperature or for radioshielding. The printed circuit board is a single part and has several levels, at least one of which is staggered axially and in alignment with the commutator. The brush-holding device has a small overall length and the electric bonding of the components can take place simply without any additional parts.
