Commutator motor, method for producing a commutator motor, and windscreen-wiper motor

Abstract

The invention relates to a commutator motor (), particularly as part of a windscreen-wiper motor (), having at least four magnet elements (to) which are arranged on a reference-circle diameter around an axis of rotation of an armature shaft () with polarity that alternates in the circumferential direction, and having an armature () with armature slots (Nto N) and armature teeth (Zto Z), wherein winding wires () having a multiplicity of windings () in each case for constructing coils (Cto C) are arranged in the armature slots (Nto N), wherein a start () and an end () of a winding wire () is electrically conductively connected to a commutator hook (Hto H) in each case, wherein a winding wire () has two winding-wire sections (), which are arranged in the region of different magnet elements (to) in such a manner that a first winding-wire section () with a first number of windings () in a first winding direction is assigned to a first magnet element (to) and is located in two armature slots (Nto N), and that a second winding-wire section () with a second number of windings () in a second winding direction, opposite to the first winding direction, is assigned to a second magnet element (to) and is located in two armature slots (Nto N), and wherein the two magnet elements (to) have different polarities.
