Abstract: The present invention relates to an unwound rotor (1) for an inductive angular displacement sensor, which rotor is rotatably movable about a first axis (X1) and symmetrical with respect to the first axis (X1), the rotor (1) having: —a central portion (10), —two active portions (20) on either side of the central portion (10) relative to the first axis (X1), each active portion (20) comprising an outer surface (21) and two connecting walls (221, 222) connecting the outer surface (21) to the central portion (10), the rotor (1) being characterised in that in a plane (P) normal to the first axis (X1), each connecting wall (221, 222) forms an angle (a) greater than 45° with a second axis (X2). The invention also describes an inductive angular displacement sensor comprising such a rotor.
