Electrical insulating element for stator, and associated stator, electric machine, sensor and aircraft

An electrical insulating element for a stator comprising a stack of magnetic sheets having at least one first stator tooth and comprising at least one first stator coil wound around the stator tooth, the first stator tooth having a first end face located at one end of the stack of magnetic sheets, the insulating element comprising an electrically insulating foil having a face coated with adhesive, the insulating element being configured to be inserted between the first face of the first stator tooth and the first stator coil, the face coated with adhesive being adhered to the first face, characterized in that the insulating element is U-shaped obtained by folding the insulating foil and configured to be fitted in a longitudinal direction of the stator on the first stator tooth so that the insulating element is further inserted between the first stator coil and side faces of the first stator tooth, the adhesive-coated face being configured to be adhered to the side faces of the first stator tooth, the insulating element being in one piece and made exclusively from the electrically insulating foil.
