1. An aircraft propulsion system comprising:
a turbomachine,
at least one electric motor comprising a first half-motor and a second half-motor, comprising, respectively, a first stator and a second stator cooperating with a common rotor of said motor,
at least one first energy source configured to provide a DC voltage,
at least one electrical generator driven by the turbomachine and configured to generate an AC voltage to form a second energy source, and associated with an active rectifier configured to transform said AC voltage into a DC voltage the value of which is controlled by said active rectifier, the first power source being connected to the output of the active rectifier,
at least one command module configured to supply and to control the speed of each half-motor, from at least one of the voltage of the first energy source and the output voltage of the active rectifier,
at least one monitoring module separate from the command module, the monitoring module being configured to remove the power supply to at least one electric half-motor if an anomaly is detected.
