Abstract
The armature (,) has metal segments (,) separated from each other by grooves (,) distributed around its circumference on a front side thereof. Commutator covers (,) are placed on the segments (,) and soldered with the segments (,) in order to form the plane commutator (,). The commutator cover (,) has respective recesses (,) in its front side facing the metal segments, which correspond in their size and shape at least approximately to the segments (,). When the commutator cover (,) is assembled in the armature each segment (,) is inserted in a corresponding recess (,) of the commutator cover (,) and is soldered in the recess (,). Side surfaces of the segments (,) facing in the circumferential direction and edge surfaces pointing radially inwardly are covered by the commutator covers (,). The commutator covers (,) are positioned exactly by the metal segments (,) inserted in their recesses and are separated from each other by comparatively small slots (,) in the armature.
