Abstract
A fan module for an aircraft turbine engine, this module comprising a fan and an electrical machine, such that the electrical machine is coaxially mounted downstream of the fan and comprises a rotor coupled to rotate with the fan and an annular member with generally C-shaped axial cross-section, the opening of which is axially orientated and receives the rotor, this member comprising a radially outer portion forming a stator, and a radially inner portion forming a support for bearings guiding the rotor.

A fan module for an aircraft turbine engine, this module comprising a fan and an electrical machine, characterised in that the electrical machine is coaxially mounted downstream of the fan and comprises a rotor coupled to rotate with the fan and an annular member with generally C-shaped axial cross-section, the opening of which is axially facing and receives said rotor, the annular member comprising a radially outer portion forming a stator, and a radially inner portion forming a support for bearings guiding the rotor, said rotor disposed radially between said radially outer portion and said radially inner portion.
A fan module for an aircraft turbine engine, this module comprising a fan and an electrical machine, wherein the electrical machine is coaxially mounted downstream of the fan and comprises a rotor coupled to rotate with the fan and an annular member with generally C-shaped axial cross-section, the opening of which is axially facing and receives said rotor, a stator being integrated with the annular member, and a radially inner portion of the annular member forming a support for bearings guiding the rotor, said rotor disposed radially between said stator and said radially inner portion.
A fan module for an aircraft turbine engine, this module comprising a fan and an electrical machine, wherein the electrical machine is coaxially mounted downstream of the fan and comprises a rotor coupled to rotate with the fan and an annular member with generally C-shaped axial cross-section, the opening of which is axially oriented and receives said rotor, the annular member comprising a radially outer portion forming a stator, and a radially inner portion forming a support for bearings guiding the rotor,
- the rotor being carried by a substantially cylindrical support element, the downstream end of which sealingly cooperates with a portion of the annular member that defines the opening, and the upstream end of which receives a closure element which sealingly cooperates with an upstream free end of said radially inner portion of the annular member,
- said closure element comprising a series of internal rectilinear splines for coupling to a series of external rectilinear splines of a connecting element to a fan disc.
