ABSTRACT:
The invention concerns a pot or cup-shaped carrier (10) for carbon brushes (12), especially intended for servomotors, comprising an inner wall, such as a bottom wall, originating from the carrier perimeter wall, and interspersed by the commutator or by a shaft originating therefrom, wherein each carbon brush is acted upon via a plate spring (14) in the direction of a commutator that is interspersed by the carrier. In order that the plate spring, which is required to act upon the carbon brushes, can be held back in a defined manner during assembly, while at the same time allowing facilitation of an easy release, without the need for removed elements, it is suggested that the inner wall have partially cut-free spring-loaded first sections, from each of which a holding section originates, which extends along the longitudinal axis of the carrier (10), wherein each holding section has a carbon brush (12) assigned to it in such a way that the carbon brush is freely displaceable in the direction of the commutator, or is held in a pulled-back position, a certain distance from the commutator.
