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.

Abstract: An electric motor stator wherein an annular central part and a yoke surrounding the central part, the central part includes a bundle of laminations delimiting poles, wherein the bundle of laminations includes a plurality of first laminations each containing portions forming a pole part that are joined by an annular internal portion, second laminations each forming a pole part being mounted between the first laminations, the first laminations being spaced apart from one another at a predetermined spacing according to a required inductance.

Abstract: An electric motor rotor including a magnetic core, magnets fastened to the periphery of the magnetic core, and a wire wound with touching turns around the magnetic core and the magnets. The wire includes a metal core surrounded by an electrically insulating layer, itself covered by an outer sheath of thermo-adhesive material, the turns being fastened to one another by adhesion between mutually contacting portions of the outer sheath. A method of fabricating such a rotor. An electric motor including such a rotor.
