A geared motor (1) for a motor-vehicle wiping system including an electric motor (2) is disclosed. The geared motor has a rotor (20) including magnetic elements, a stator (21) having the electromagnetic excitation windings, a rotary shaft (22) rigidly connected to the rotor, a reduction gear (3) linking the rotary shaft (22) and an output shaft of the geared motor, and a casing (4) forming a protective envelope for said reduction gear or the electric motor (2). The reduction gear (3) includes a worm screw and worm wheel gear, the worm screw (30) being rigidly connected to the rotary shaft of the rotor (22), the worm wheel (31) rigidly connected to an output shaft (8) of the geared motor, bearing means (23, 24) for guiding the rotary shaft of the rotor (22) in rotation in relation to the casing (4), and a determination device for determining the angular position of the rotor including a multi-pole magnet (5) that is rigidly connected to the rotary shaft (22) of the rotor (20).
