Abstract: An end shield for a rotary electric machine includes a plate which extends generally transversely in relation to an axis (X), and a skirt which extends generally axially from the plate. The skirt has at least one shoulder which forms an axial stop, the shoulder being intended to axially block a stator body of the rotary electric machine. The shoulder extends only over a portion of the circumference of the skirt.

Abstract: An alternator having a rotor and a stator is described. The stator includes a cylindrical body with a plurality of phases. Each of the plurality of phases includes a phase input located at least partially outside of the cylindrical body, where the phase input is formed of a bar. The bar includes a longitudinal surface extending along at least a part of the bar, a first segment crossing the cylindrical body, and a second segment extending from an axial side of the cylindrical body. Each of the plurality of phases further includes a phase output located at least partially outside of the cylindrical body and conducting elements crossing the cylindrical body and forming at two axially opposite sides of the body, respectively, a first chignon and a second chignon. The conducting elements are electrically connected to form at least one winding connecting the phase input to the phase output.

Abstract: The invention relates to an alternator for a motor vehicle including a stator (13) equipped with a body (14) carrying several phases each comprising, on the one hand, an inlet (E1 to E?3) and an outlet (S1 to S?3) installed outside the body (14) of the stator (13), and, on the other hand, electrically conducting elements, which are arranged in a network on either side of the body (14) of the stator (13) so as to form a first (12) and a second (12?) bun and which pass through the said body, in which the electrically conducting elements are linked together to form the said networks and connect the inlet of the phase to the outlet of the phase by forming at least one winding. According to the invention, one of the buns (12, 12?), on one side of the body (14) of the stator (13), carries three inlets (E1 to E3–E?1 to E?3), an electrically conducting linking part (50, 51) linking the said inlets electrically together.

Abstract: An alternator, in particular for a motor vehicle, comprises half-shells to which stator windings are fixed and which rotatably receive a rotor shaft, and a rectifier circuit made up of power diodes each comprising body and a lead extending axially from said body. The bodies of some of the diodes are connected to ground while the bodies of the other diodes are connected to an output terminal of the alternator. The diode bodies are fixed on or in the back half-shell of the alternator on or in a dissipating support which is generally in the form of a plate that is insulated from the half-shell and that is outside it. According to the invention, the distance between the dissipating support and the back half-shell, and the positions of the said other diodes on the dissipating support are such that the leads of said other diodes project into openings formed in the back half-shell.
