Abstract
The invention concerns an arrangement for supplying power to an electric motor having a commutator, comprising at least two carbon brushes (), as well as flat springs () that subject said brushes to force in the direction of the commutator and proceed from a mounting and are connected to electric terminals. In order to enable a defined transfer of force from the flat springs to the carbon brushes, while at the same time ensuring that an unambiguous fixing of the flat springs into position and a secure current supply takes place, it is proposed that the flat springs () have a U-shape with legs () of unequal length, that a carbon brush () be fastened to each longer leg, and that the shorter leg be connected electrically conductive to an at least partially encapsulated conductor path or printed circuit, which is at least a section of the mounting.
