Beschreibung
Zusammenfassung:	A turbomachine having a longitudinal axis, the turbomachine comprising an annular rotor centered on the longitudinal axis of the turbomachine, an annular stator disposed coaxially around the rotor, at least one ball bearing disposed on the rotor and rotatably supporting said stator, the inside of the rotor defining part of an oil enclosure for cooling and lubricating the balls of the bearing, an electricity generator having a secondary magnetic circuit secured to the stator and a primary magnetic circuit constrained to rotate with the rotor, and a detector device for automatically detecting ferromagnetic particles in the oil enclosure, said detector device being powered electrically by electromagnetic induction.
