Abstract
An electrical machine having an armature that is rotatable in a stator. The armature has a winding that is energized via a commutator or via slip rings cooperating with brushes. A holding plate is provided on which the brushes are held and which is supported freely shiftable in the direction of the axis of rotation of the machine, but circumferentially immovable. The holding plate butts against a part that is supported axially immovable on the shaft of the armature, preferably a bearing. Spring means acting between the holding plate and an adjacent side plate of the stator or housing serves to bias the holding plate in an axial direction. The part against which the holding plate butts, lies preferably in or near the plane of the holding plate.
