Abstract
A brush-commutated direct-current motor comprises a stator which includes a plurality of exciter poles, a rotor rotatable relative to the stator about an axis of rotation, a plurality of pole teeth arranged on the rotor, and grooves arranged between the pole teeth, wherein the pole teeth are separated from each other by the grooves along a circumferential direction around the axis of rotation. On the pole teeth coil windings are arranged. A commutator is arranged on the rotor and includes a plurality of lamellae, wherein each coil winding is connected with one of the lamellae via a first connecting arm and is connected with another one of the lamellae via a second connecting arm.
