ELECTRICAL COMMUTATOR FOR WIPER BLADE DRIVE SYSTEM AND CORRESPONDING DRIVE SYSTEM

摘要

The invention relates to an electrical commutator for a wiper blade drive system (10) of a motor vehicle glazed panel including a motor (16), said commutator comprising: - at least one drive wheel (22) driven by said motor (16) in rotation about an axis of rotation (C), and - a means (44) for detecting the angular position of the wheel (22) about the first axis (C). According to the invention, said wheel (22) carries at least one conductor track (46) and at least one insulating region (47a, 47b) extending in a plane substantially parallel to the plane defined by said at least one conductor track (46 ), and said at least one insulating region (47a, 47b) being arranged at a distance (h) from said at least one conductor track (46) in a direction (Z) substantially perpendicular to the plane defined by said at least one conductor track (46), and said detecting means (44) comprises three conductor contact blades (48, 48', 48") arranged so as to come in contact with said wheel (22) and being angularly offset with respect to one another.
