    Abstract: The disclosure relates to an assembly for an aircraft turbomachine, having a speed reduction gear comprising an input pinion connected to a power shaft of the turbomachine and an output pinion connected to a propeller shaft of the turbomachine. According to the disclosure, the assembly includes two electric machines which are each configured to provide electrical power to the propeller shaft or to draw mechanical power from the propeller shaft, each electric machine comprising a rotor and a stator, the stator configured to be connected to a casing of the turbomachine. The speed reduction gear can include two substantially parallel intermediate transmission lines configured to transmit the torque from the input pinion to the output pinion, each rotor being driven in rotation respectively by a pinion of an intermediate line.
