1. A fan module for an aircraft turbomachine, comprising:
a fan comprising a disc carrying fan vanes,
a rotor of an electric machine the rotor being annular in shape and being mounted coaxially downstream of the fan,
an annular support for the rotor, a downstream end of which is attached to said rotor and an upstream end of which is attached to the disc,
wherein the support is attached to the disc by means of fusible screws configured to break when a torsional torque transmitted from the disc to the support exceeds a predetermined threshold.
