Abstract
The invention relates to a planetary gear reducer () for an aircraft turbine engine (), the reducer () comprising a sun gear () and a ring gear () which are centred on a longitudinal axis X and a planet carrier () which carries at least one planet gear () rotatably mounted about a planet axis A parallel to the longitudinal axis X, the sun gear () being rotatable about the longitudinal axis, the planet gear () meshing both with the sun gear () and the ring gear (), the planet carrier () being movable about the longitudinal axis and the ring gear () being rotationally fixed. According to the invention, the reducer () comprises an electric machine () integrated therewith and which comprises a rotor () mounted on the planet carrier () in such a way as to be rotated about the longitudinal axis X and a stator () mounted on the ring gear ().
