Abstract: The invention relates to a geared motor comprising a first brushless electric motor part having a stator, a rotor and a drive shaft, a second part having an output shaft and a reduction gear mechanism and an electronic part. The reduction gear mechanism comprises an output shaft, a worm and a toothed wheel designed to be engaged by the worm and to drive the output shaft in rotation. The geared motor comprises at least one rolling guide bearing disposed on the drive shaft and a multipolar magnet for measuring the position of the rotor. The rolling bearing is disposed between the measurement magnet and the worm such that the electric motor can be controlled depending on the measurement of the position of the rotor.
