The invention relates to a wiper motor (), with an output shaft () which rotates in exclusively one direction () and is designed at least indirectly to move at least one wiper blade () between two reversal positions (A, B). According to the invention, it is provided that the wiper motor () has means () which are designed at least indirectly to activate a pump () for conveying a cleaning fluid in such a manner that cleaning fluid can be applied to a vehicle window () exclusively in front of the wiper blade () in the respective wiping direction.

Wiper motor and wiping apparatus for wiping a vehicle window

A windscreen wiper motor with a housing is disclosed. In the housing, an armature shaft is arranged with a commutator which cooperates with carbon elements arranged in the region of a carbon holder plate, which elements are connected in an electrically conducting manner with voltage supply lines via electrical connections, preferably in the form of carbon strands. The voltage supply lines are connected with the electrical connections via a suppression device arranged at least substantially in a suppression housing, which is connected with the carbon holder plate, and the voltage supply lines are connected with at least one plug connection element, which is able to be connected to a plug connection region of the housing with mating plug connectors on the vehicle side.

Windscreen wiper motor and suppression assembly for a windscreen wiper motor

The invention relates to an arrangement () for determining the angular position of a shaft () of an electric motor (), in particular of a shaft () of a windscreen wiper motor (), with a magnet element arrangement, connected with the shaft (), and several magnetic field sensors (), wherein the angular position of the shaft () is inferred from the different signals of the magnetic field sensors (). Provision is made, according to the invention, for the magnet element arrangement to comprise at least one magnet element, preferably several separate magnet elements (), which are arranged one behind the other in the longitudinal direction of the shaft (), and for the magnetic field sensors () to be arranged on a printed circuit board () which is arranged at a slight distance from the shaft (), such that the magnetic fields of the magnet elements () are able to be determined by the magnetic field sensors ().
