Abstract

A brush-commutated direct-current motor comprises a stator with a plurality of exciter poles, a rotor with a plurality of pole teeth, which is rotatable relative to the stator about an axis of rotation, grooves arranged between the pole teeth, and coil windings arranged on the pole teeth and a commutator which is arranged on the rotor and a plurality of lamellae to which the coil windings are connected. For manufacturing such direct-current motor the coil windings are arranged on the pole teeth in winding cycles, in each of which a coil winding is wound onto each pole tooth. It is provided that on each pole tooth 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 are arranged.
