Abstract
A turbomachine includes a high-pressure spool, an axial compressor of axis X mounted on a rotor and including a casing and at least one rear bearing disposed between the casing and the rotor of the compressor. The turbomachine further includes an electricity generator coaxial with the spool and including a primary magnetic circuit that is constrained to rotate with the rotor of the compressor and a secondary magnetic circuit that is secured to the casing. The electricity generator is disposed upstream from the rear bearing and includes at least a first cooling circuit surrounding the secondary magnetic circuit and extended by a nozzle for lubricating the rear bearing.
