Abstract: Hammer brush holders (2) are plugged or snapped together as pivoting bearings with cupped bearing receptacles (2.2;2.3) arranged radially on knife-edge bearings (1.2;1.3) of a motor stator part, in particular a bearing bow (1). To prevent tilting due to forces acting perpendicularly to the hammer brush holder's pivotal motion, in particular those arising during assembly and transport, a securing pin (2.1) of the hammer brush holder (2) extends or locks into a securing notch (1.1) of the motor stator part.

Abstract: A brush holder for an electrical machine, and in particular a hammer brush holder, can include a carbon brush inserted with one of its ends provided with a brush shunt into a pot-shaped receptacle part of the brush holder. The carbon brush is retained in the receptacle part by means of clamping. A reliable clamping of the carbon brush is guaranteed by providing a scraper rib on at least one side wall of the receptacle part and designing it to ascend from the entry slot of the receptacle part toward its pot-like bottom with respect to its height and/or its width pointing into the receiving space of the receptacle part. The brush holder may be manufactured from plastic, and the carbon brush is inserted with a clamp locking force fit into a receiving opening of the brush holder.
