ABSTRACT:
The invention relates to an arrangement for holding and/or guiding and applying power to a carbon brush (16, 18) in the direction of a current-transferring commutator (14) comprising a first spring element (20), which acts upon the side of the carbon brush facing away from the contact surface. To ensure that the carbon brush is supplied with the necessary pressure in the direction of the commutator, it is suggested that a second spring element (52, 56, 56), which supplies power to the carbon brush (16, 18) in the direction of the commutator (14), act upon the first spring element (20).
