Brush-commutated direct-current motor

A brush-commutated direct-current motor, comprising

• a stator which has 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,
• 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,
• coil windings arranged on the pole teeth, and
• a commutator which 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,
• wherein each pole tooth carries a first coil winding wound around the pole tooth in a first winding direction and a second coil winding wound around the pole tooth in a second winding direction opposite to the first winding direction, wherein the first connecting arm and/or the second connecting arm of the first coil winding is laid around at least one other pole tooth towards a respectively associated lamella.
