Method for producing a brush-commutated direct-current motor

A method for manufacturing a brush-commutated direct-current motor, which includes

• a stator with a plurality of exciter poles,
• a rotor rotatable relative to the stator about an axis of rotation, comprising a plurality of pole teeth, grooves arranged between the pole teeth, and coil windings arranged on the pole teeth, and
• a commutator which is arranged on the rotor and includes a plurality of lamellae to which the coil windings are connected,
• wherein the coil windings are arranged on the pole teeth in winding cycles in which one coil winding each is wound onto each pole tooth,
• wherein 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, wherein
• in a first winding cycle the first coil windings are wound on a first part of the pole teeth and the second coil windings are wound on a second part of the pole teeth, and
• in a second winding cycle the second coil windings are wound on the first part of the pole teeth and the first coil windings are wound on the second part of the pole teeth.
