Abstract: The system concerns a gear motor for a motor vehicle wiping system comprising:—an electric motor comprising a rotor, a stator and a rotating shaft solidly attached to the rotor,—a reducing mechanism connecting the rotating shaft and an output shaft of the gear motor. According to the invention, a roller bearing (23) guides the rotating shaft (22) at one of the longitudinal ends of the rotating shaft, said roller bearing (23), arranged inside the rotor and stator assembly, housed in an inner recess of the rotor, and in which a hollow support bears the magnetic elements and is arranged coaxially and connected in rotation with the rotating shaft (22), said hollow support (25) covering said roller bearing (23) guiding the longitudinal end of the rotating shaft (20) on the side of the electric motor (2), the axial locking of the roller bearing (23) on the rotating shaft (22) being obtained by pressing against the inner race of the roller bearing (23) on the inner wall of the hollow support (25), directly or indirectly through the intermediary of a spacer (8).

Abstract: A wiper motor control circuit carries out control in which a driving circuit generates, and supplies to a wiper motor, a voltage that eliminates deviation between a target speed and an actual speed of an output shaft. In a case in which a state in which the deviation between the target speed and the actual speed is greater than or equal to a predetermined threshold value continues for a predetermined time or more, the wiper motor control circuit carries out control that lowers the target speed and in which the driving circuit generates, and supplies to the wiper motor, a voltage that eliminates deviation between the lowered target speed and the actual speed of the output shaft.
