Abstract
The present invention relates to an inductive position sensor (1) for a rotating electric machine, the sensor having a printed circuit board (12) housed in at least one housing (10, 100, 11, 19, 101, 102, 103, 104, 15), the printed circuit board (12) having, on its main face (120), at least one emission element intended to emit an oscillating magnetic field toward a rotating target (2) in order to generate a modified oscillating magnetic field, and at least one receiving device intended to detect the modified oscillating magnetic field, the sensor having fluid circulation means (16, 17, 18, 166, 165), the fluid circulation means being formed by at least one duct (16, 17, 18), for allowing fluid to circulate into the interior of a rotor shaft (22, X) of the electric machine, the printed circuit board (12) being arranged such that its main face (120) faces the target (2).
