Summary:The invention concerns a rotor for a rotary electric machine, the rotor having an axis of rotation and comprising:- a rotor shaft extending parallel to the axis of rotation;- a rotor body (7) mounted on the rotor shaft and having a plurality of teeth protruding radially;- at least one field coil wound around the plurality of teeth, said field coil forming coil ends at axial ends of the teeth;- at least one cover (15) mounted on the rotor shaft and configured to cover the coil ends, said cover having a mounting opening (16) receiving a portion (17) of the rotor shaft so that the cover and the portion of the rotor shaft exert reciprocal radial force on each other to ensure the fixation;characterized in that said mounting opening (16) and said rotor shaft portion have, in a cross-section perpendicular to the axis of rotation, form-fitting profiles (18) which are defined by a contour (19) having a plurality of points (A, B) that are at different distances from the axis of rotation.
