Abstract
An electric module for an aircraft turbomachine includes an electric machine stator having an annular shape around an axis (A) and being configured to surround a rotor of the electric machine, and an annular support element of the stator. The support element includes an outer annular surface configured to be swept over by a gas stream (F) from the turbomachine with a view to conductively cooling the stator.
Claims15
An electric module for an aircraft turbomachine, the electric module comprising:
- a stator of an electric machine, said stator having an annular shape about an axis (A) and being configured to surround a rotor of the electric machine,
- an annular support element for said stator, said annular support element comprising an external annular surface configured to be swept by a gas flow from the aircraft turbomachine, the gas flow cooling the annular support element,
- said annular support element comprising:
- an annular support which surrounds and covers at least one portion of said stator and which is attached to an external periphery of the stator, the annular support comprising at least one flange configured to attach to a member of the aircraft turbomachine and being located at a downstream end of the stator, and
- an annular cover which surrounds at least one portion of said annular support and which comprises said external annular surface swept by the gas flow, said gas flow cooling the annular cover,
- wherein said annular cover is in radial abutment against said annular support along an entirety of an axial extent of the stator so as to cool the stator by radial conduction through the annular cover and through annular support along the entirety of said axial extent.
