The present invention relates to a contact-disk system including a control unit, a rotatable contact disk and a plurality of contact elements, the contact disk having a plurality of paths and each contact element being associated with one path. The paths have electrically conductive segments and electrically insulating segments, logical states being encoded by the electrically conductive segments and the electrically insulating segments. The contact disk has n paths with n&gE;2, and N logic states are encoded by the n paths and by the sequence of the electrically conductive segments and the electrically insulating segments, with N>2 . The present invention also relates to a method for controlling a windshield-wiper motor and a windshield-wiper motor having a contact-disk system according to the present invention.

Contact washer system and method for controlling a windscreen wiper motor

An electric motor, in particular a wiper motor, for wiping a window of a motor vehicle, having a gearing situated in a gear housing, a cover closing the gear housing, and a control electronics having a sensor device, which detects the position of the gearing and records the signals of a signal transmitter situated at or in a movable part of the gearing, elements of the sensor device being situated in the cover or at least on the side of the gearing facing the cover and determining the position of the gearing without contact.
