The engine has a controller (19) provided with an output unit (18) for providing a supply voltage to a sensor (13), and an input unit (23a, 23b) for receiving a signal from the sensor to calculate the position of a core (15). A remote energy transmission unit (22) comprises a group of reels (20, 21,24a, 24b, 25a, 25b) arranged to transmit energy by mutual induction between the reels. The reels of the transmission unit are connected to the sensor and the controller, where the sensor is mounted on a rotor, and the controller is mounted on a stator. L'invention concerne une turbomachine comportant au moins un capteur de position inductif (13) de type LVTD monté sur un rotor et un calculateur (19) monté sur le stator, reliés par l'intermédiaire de moyens (22) de transmission d'énergie à distance tel qu'un transformateur tournant.
