The present disclosure relates to a gear motor formed of a housing. An electric motor includes a stator assembly and a rotor driving a reduction gear train having a plurality of intermediate stages each formed by a shaft coupled to a toothed wheel and to a toothed gear. Also, an output stage is formed by a shaft coupled to a wheel and a coupling component, the shafts of the rotor, of the intermediate stages and of the output wheel being parallel. The gear motor further includes a printed circuit transversely positioned above the stator assembly, wherein the wheel of the output stage is positioned above part of the stator assembly, the shafts of the intermediate stages are located in the zone of the housing located on the opposite side, relative to a transverse vertical plane, of the zone including the shaft of the rotor and the shaft of the output wheel.
