    The invention relates in particular to a stator for a rotating electrical machine. The invention finds a particularly advantageous application in the field of rotating electrical machines such as alternators or reversible machines. It will be recalled that a reversible machine is a rotating electrical machine able to work in a reversible manner, on the one hand, as an electric generator in alternator function and, on the other hand, as an electric motor in particular for starting the engine of the motor vehicle.
    A rotating electrical machine comprises a rotor rotatable about an axis and a fixed stator surrounding the rotor. In alternator mode, when the rotor is rotating, it induces a magnetic field to the stator which transforms it into electric current to power the vehicle electronics and recharge the battery. In motor mode, the stator is electrically powered and induces a magnetic field driving the rotor in rotation.
    The stator is provided with an electrical winding comprising a plurality of phase-forming electrical conductors. When the coupling of the winding is of the star-coupling type, each phase comprises a neutral point and a connection point corresponding to an input or a phase output. The stator winding therefore comprises a plurality of neutral points and a plurality of connection points distributed along a periphery of the stator. The neutral points of the same phase system must be connected together without creating an electrical short circuit with the connection points in order to ensure a good electrical supply of the stator winding.
    The present invention aims to improve the stators.
    The present invention aims in particular to allow to connect the neutral points of the same phase system between them without creating an electrical short circuit with the connection points.

    This makes it possible to connect the neutral points while avoiding electrical contact with the connection points. Thus, the neutral points of the same phase system are electrically connected so as to form a single neutral point per phase system without the risk of an electrical short circuit with the connection points. In addition, thanks to the invention, the electrical connection between the neutral points of the winding can be relatively robust and a good power supply of the winding can be guaranteed.

    FIG. 1 represents a rotating electrical machine 1 compact and polyphase, in particular for a motor vehicle. This rotating electrical machine 1 transforms mechanical energy into electrical energy, into alternator mode, and can operate in motor mode to transform electrical energy into mechanical energy. This rotary electrical machine 1 is, for example, an alternator or a reversible machine.
    The rotary electrical machine 1 comprises a housing 2. Inside this housing 2, it further comprises a shaft 3, a rotor 4 integral in rotation with the shaft 3 and a stator 5 surrounding the rotor 4. The rotational movement of the rotor 4 is around an axis X. In the remainder of the description the radial, ortho-radial and axial orientations are to be considered with respect to this axis X.
    In this example, the housing 2 comprises a front bearing 6 and a rear bearing 7 which are assembled together. These bearings 6, 7 are of hollow form and each bear, centrally, a respective ball bearing 10, 11 for the rotational mounting of the shaft 3.
    A pulley 12 is fixed on a front end of the shaft 3, at the front bearing 6, for example by means of a nut bearing on the bottom of the cavity of this pulley. This pulley 12 transmits the rotational movement to the shaft 3. The rear end of the shaft 3 carries, here, slip rings belonging to a collector. Brushes belonging to a brush holder 8 are arranged so as to rub on the slip rings. The brush holder 8 is connected to a voltage regulator included in a rectifier bridge 9.
    The front bearing 6 and the rear bearing 7 may further comprise substantially lateral openings for the passage of air in order to allow the cooling of the rotary electric machine by air circulation generated by the rotation of a fan. before 13 on the front dorsal face of the rotor 4, that is to say at the front bearing 6 and a rear fan 14 on the rear dorsal face of the rotor, that is to say at the level of the bearing back 7.
    In this exemplary embodiment, the stator 5 comprises a body 15 in the form of a pack of sheets with notches, for example of the semi-closed or open type, equipped with slot insulator for mounting an electric winding. 16. This coil 16 passes through the notches of the body 15 and form a front bun and a rear bun on both sides of the stator body. This winding 16 is obtained, for example, from a continuous wire covered with enamel or from conducting elements in the form of bars such as pins connected together.
    In this example, the rotor 4 is a claw rotor. It comprises two pole wheels 17. Each pole wheel 17 is formed of a flange 18 and a plurality of claws 19 forming magnetic poles. The flange 18 is of transverse orientation and has, for example, a substantially annular shape. This rotor 4 further comprises a cylindrical core 20 which is interposed axially between the pole wheels 17. Here, this core 20 is formed of two half-cores each belonging to one of the pole wheels 17. The rotor 4 comprises, between the core 20 and the claws 19, a coil comprising, here, a winding hub 22 and an electric winding 21 on this hub. For example, the collector rings belonging to the collector are connected by wire bonds to said coil. The rotor 4 may also comprise magnetic elements interposed between two adjacent claws.
    When the electric winding is electrically powered from the brushes, the rotor 4 is magnetized and becomes an inductor rotor with formation of north-south magnetic poles at the claws 19. This inductor rotor creates an alternating induced current in the stator induced when the shaft 3 is rotating. The rectifier bridge 9 then transforms this AC induced current into a direct current, in particular to supply the loads and the consumers of the motor vehicle's onboard network as well as to recharge its battery.
    In addition, in the example of FIG. 1, the electric winding 16 is connected in a star.
    The stator 5 extends around the axis X and comprises: the electric winding 16, this winding comprising a plurality of electrical conductors forming phases, each phase comprising: an electric neutral point formed by an end of an electrical conductor and a connection point 24 of an input or a phase output formed by another end of an electrical conductor, these neutral and connection points being on the same circumference; and an electrical connector comprising at least one electrical connection member which is arranged to electrically connect at least two neutral points, this connector having a shape that bypasses the connection points.
    As illustrated in the example of Figure 2, the connector 25 is mounted on an apex of a winding bun 16. In particular here, the connector 25 is mounted opposite the rear bearing 7 of the rotary electric machine 1 and therefore on the back bun.

    In this example, the connecting member 26 comprises at least one radial recess 27 which extends along an arc of a diameter smaller than that of the circumference on which are arranged the neutral points 23 and 24 connection. Preferably, the radial recess 27 may be arranged at a non-zero radial distance from the connection points 24.
    In FIG. 3, the connecting member 26 comprises at least one axial recess 28 which extends on the same circumference as that in which the neutral 23 and connection 24 points are located. Moreover, in the examples illustrated here, the coil 16 comprises at least one electrical conductor having a section overlapping an apex of the bun. The axial recess 28 is preferably arranged at a non-zero axial distance of this section, on an axial side opposite the top of the bun.
    In the example described here, the connector 25 comprises a plurality of sections 29 of connecting members 26 connecting at least two neutral points 23 between them. Preferably, the sections 29 are arranged along the same circumference.
    Alternatively, the connecting member 26 could be formed of a single section 29 arranged to electrically connect the neutral points 23.
    In addition, the connecting member 26 is arranged to form a space for the insertion of an electrical conductor end forming a neutral point 23. For example, at least two neighboring sections 29 are arranged to form this space.
    Preferably, the connecting member 26 is welded to the associated neutral points 23. Thus, the connecting member 26 is welded to all the neutral points 23 that must be connected together. In particular, the welding is done by resistance brazing or by electric arcs or by soldering or by laser.
    In the example of Figure 3, each section 29 comprises a lug 30, in particular at one end of said member, this lug extending substantially axially. Some of the sections 29 comprise, here, two lugs 30 located at the respective ends of said sections facing the corresponding neutral point 23.
    Each neutral point 23 is here in electrical contact with two tabs 30 of neighboring sections 29, these tabs 30 being in particular arranged opposite one another.
    In this example, each section 29 comprises at least one elbow 31, in particular rounded, facing the winding 16 and being arranged to facilitate the insertion of a conductor end forming a neutral point 23. Where appropriate, the elbow 31 is here formed at the junction between the tab 30 and the rest of the section 29.
    Preferably, the connecting member 26 is made of copper.
    Figure 4 illustrates in more detail the connector 25.
    In the examples described here, the connector 25 further comprises an electrically insulating body 32 which carries the connecting member 26. Preferably, the insulating body 32 comprises a plastic material. The connector extends here on a circular arc.
    Preferably, the insulating body 32 is obtained by overmolding the connecting member 26. Always preferably, the connecting member 26 is embedded in the insulating body 32 over a major part of its length.
    In the example of FIG. 4, the insulating body 32 comprises at least a first radial notch 33 arranged to allow the passage of at least one electrical conductor end forming a connection point 24. For example, the radial notch 33 is emerging on an outer periphery of the connector 25.
    Still in this example, the insulating body 32 further comprises at least a second radial notch 34 arranged to receive at least one lug 30 and at least one electrical conductor end forming a neutral point 23. This radial notch 34 is, for example, example, opening on an outer periphery of the connector 25.
    In addition, the connector 25 comprises, in the example of Figure 4, at least one orifice 35 formed in the insulating body 32 and arranged to receive an electrical conductor end forming a connection point 24.
    In the example of FIGS. 2, 3 and 4, the winding 16 is of double three-phase type, with in particular two phase systems each having three neutral points 23. The connector 25 then comprises two connecting members 26 each being arranged to to electrically connect the neutral points 23 of the same phase system. As a variant, the stator 5 could comprise two connectors 25 such as that illustrated in FIG. 6, each being arranged to make it possible to electrically connect all the neutral points 23 of the same phase system of the winding.
    In a variant embodiment where the winding would be of simple three-phase type, the stator 5 would then comprise a single connector 25 as illustrated in the example of FIG.
    In the examples of FIGS. 2 and 7, the stator 5 further comprises at least one temperature measuring probe 36 carried by the connector 25 and comprising at least one sensitive element 37 arranged to measure the temperature of the winding 16. The sensitive element 37 is here arranged to be in thermal contact with a connecting member 26 of the connector 25, the connecting member 26 being in thermal contact with an electrical conductor of the coil 16. In particular, sensing element 37 and connecting member 26 are in direct contact with each other.
    The measurement probe 36 may have different locations along the connector 25. In the example of FIG. 2, the measurement probe 36 is positioned at one end of the connector 25. In the example of FIG. 7, said probe is positioned between two neutral points 23.
    For example, the connector 25, in particular the insulating body 32, comprises a housing 38 intended to receive the measurement probe 36. Preferably, the housing 38 comprises a thermally conductive material 39 in which at least part of the probe is embedded. This material 39 is, for example, a varnish or a resin or an adhesive. The sensitive element 37 is here positioned in the housing 38 in axial contact with the connecting member 26.
    In these examples, the connector 25 comprises a cover 40 arranged to close the housing 38. In addition, the closure of the cover 40 is provided by a latching device 43.
    In the example illustrated in FIG. 8, the measuring probe 36 is inserted in a housing 41. In a variant, in the example of FIG. 9, the measuring probe 36 could be latched via a latching device 45.
    In the example illustrated in FIG. 8, the measuring probe 36 is carried by the cover 40. In this example, the cover 40 is connected to the remainder of the connector 25 via a hinge 42.
    In a variant, in the example illustrated in FIGS. 9 and 10, the measurement probe 36 is carried by the housing 38. For example, the measurement probe 36 is snapped onto a bottom of the housing 38. Still in this example, the cover 40 may be attached to the connector 25 and snapped to the rest of said connector.
    Preferably, the measurement probe 36 is a negative thermal coefficient (NTC) sensor.
    The measurement probe 36 comprises, here, at least one electrical wire 44 arranged to transmit an electrical signal to an electronic assembly, the electronic assembly being mounted in particular on the rotary electrical machine 1. For example, the housing 38 comprises an orifice allowing the passage of at least one electrical wire 44 to the electronic assembly.
    A connector as previously described makes it possible to electrically connect the neutral points while avoiding electrical contact with the connection points. Indeed, the neutral points are at an electric potential of mass while the points of connection are connected to the bridge rectifier and present a different electric potential from that of the neutral points. The present invention thus makes it possible to electrically connect the neutral points of the same phase system to each other by reducing the risks of short-circuiting with the connection points. In addition, the present invention achieves this result in a simple, inexpensive, reliable manner and maintains optimum performance of the rotating electrical machine.
    The present invention finds applications in particular in the automotive field stators for alternator or reversible machine of a motor vehicle but it could also apply to any type of rotating machine.
    Of course, the foregoing description has been given by way of example only and does not limit the scope of the present invention which would not be overcome by replacing the various elements by any other equivalents.
