An accessory gearbox houses at least one gear train with a series of pinions. The casing has two substantially flat and opposite parallel side walls between which are mounted support shafts for each of the pinions, each of which receives accessories, and which define in the enclosure an internal volume surrounding a shaft supporting at least one hybridization pinion. The gearbox receives at least one electric machine having a rotor and a stator, wherein the rotor of the electric machine is supported by the shaft supporting the hybridization pinion of the gear train, and the stator extends around the rotor in the internal volume.
