Abstract
(EN)
Aircraft turbine engine (10) comprising: - a gas generator (12) having a longitudinal axis (A), - a fan (14) which is located at an upstream end of the gas generator and which is configured to rotate about the axis, and - an electric machine (70) which has a generally annular shape, is mounted coaxially downstream of the fan and comprises a rotor (70a) which is coupled in terms of rotation to the fan, and a stator (70b) which is connected to an electronic power circuit (78) by at least one rigid electroconductive bar (80).
