    [0001] The invention relates to a rotor for a rotating electrical machine. The invention finds a particularly advantageous application in the field of rotating electrical machines such as alternators or alternator-starters. It will be recalled that an alternator starter 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 movable in rotation and having a constant machined outer diameter. This rotating electrical machine further comprises a fixed stator surrounding the rotor. The rotor and the stator are separated from each other by a gap of constant width. 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 addition, motor vehicles have a consumption of electrical energy increasingly important, so we ask the rotating electrical machines to be more and more efficient in order to provide the necessary electrical energy. One solution for improving the performance of a rotating electrical machine is to increase the speed of rotation of the rotor. Indeed, it increases the flow of the rotating electrical machine.
    [0002] However, increasing the rotational speed amplifies the centrifugation effect corresponding to the mechanical deformation of rotor claws. Because of the centrifugation, the claws of the rotor could then rub on the internal diameter of the stator and thus destroy the rotating electrical machine or at least damage it.
    [0003] To avoid the risk of friction between the rotor and the stator, the width of the gap must be increased. However, increasing this width amounts to moving the rotor away from the stator, which causes a decrease in the performance of the rotating electrical machine.
    [0004] The present invention aims to avoid the disadvantages of the prior art. Thus, the present invention aims at making it possible to produce a rotating electrical machine whose electromagnetic performances are improved while guaranteeing a good holding of said rotating electric machine at centrifugation. The present invention therefore relates to a rotor for a rotating electric machine. According to the present invention, the rotor is rotatably mounted about an axis and has a pair of pole wheels each having a flange and a plurality of magnetic poles, each magnetic pole extending axially from the flange to one end. free and having an outer surface, said outer surface of at least one magnetic pole of at least one pole wheel having at least one decreasing segment, said decreasing segment being configured such that a radius between said outer surface and the axis of the rotor decreases, as one moves, along said decreasing segment, towards the free end of said magnetic pole. The descending segment is further defined as a segment belonging to a sectional plane comprising the rotational axis of the rotor and extending on the axial outer surface of a magnetic pole between a first end and a second end. end so that the distance between the axis of rotation and the first end of the segment is greater than the distance between the axis of rotation and the second end of the segment which is closer to the free end of said magnetic pole than The first end. In other words, the outer surface of the magnetic pole does not extend parallel to the axis of the rotor but towards the axis of the rotor when one moves towards the free end of the magnetic pole. Thus, the outer diameter of the rotor at said magnetic pole is not constant along the axis of the rotor.
    [0005] A radial width of an air gap, defined as a space between the outer surface of the rotor and an inner surface of a stator associated with said rotor, is therefore not constant. In addition, this also allows the air gap to have a width, in a radial direction, which increases when moving axially towards the free end of said magnetic pole. The fact that the width of the air gap increases when one moves toward the free end of the magnetic pole, makes it possible to obtain an air gap width that is both: - relatively small at the level of the portion of the air gap; magnetic pole where the passage of the magnetic flux from the rotor to the stator is the largest, that is to say for the portion of the magnetic pole close to the flange and 10 - relatively large at the free end of the magnetic pole which is the most sensitive zone to the holding in mechanical centrifugation during the rotation of the rotor. Indeed, by acting in particular on the part of the magnetic pole of the rotor comprising the free end, the mechanical stresses on the overall centrifugation of the magnetic pole are reduced. This therefore makes it possible to reduce the minimum value of gap width while keeping a gap width, at the free end of the magnetic pole, acceptable to avoid any contact between the rotor and the stator, when the rotor is in contact. rotation.
    [0006] A rotor having such an outer surface is thus adapted to allow both the centrifugation hold and an increase of the electric current produced by the corresponding rotating electric machine at a given speed. Moreover, a rotor having such an outer surface is also adapted to allow, for a given airgap width, the increase in the speed of rotation of the rotor which thus makes it possible to increase the electric current produced by the electric machine. rotating. Advantageously, the radius decreases, along the decreasing segment, substantially linearly. This makes it possible to improve the centrifugation behavior of the rotor as well as to simplify the manufacture of the rotor. Advantageously, the radius decreases along the decreasing segment at an angle less than or equal to 20 ° with respect to the axis of the rotor. This angle value allows balancing between the improvement of the electric current flow of the rotor and its good resistance in centrifugation. In addition, the decreasing segment advantageously has a length, in an axial direction, between 0.2 and 1 times the length of the outer surface of the corresponding magnetic pole. Advantageously, the decreasing segment has two ends, one of which ends coincides with the free end of the magnetic pole. In an advantageous embodiment of the invention, the outer surface has, in addition, a chamfered segment extending from an outer axial end of the flange. The chamfered segment extends in a cutting plane comprising the axis of rotation of the rotor, on the axial outer surface of a magnetic pole, between a first end and a second end so that the distance between the axis the first end of the chamfered segment is less than the distance between the axis of rotation and the second end of the chamfered segment which is closer to the free end of said magnetic pole than the first end. This chamfered segment improves the balancing of the rotor.
    [0007] In another advantageous example of implementation of the invention, the outer surface has, in addition, at least one constant segment configured so that the radius between said outer surface and the axis of the rotor is constant, the along said constant segment. The constant segment extends in a cutting plane comprising the axis of rotation of the rotor, on the axial outer surface of a magnetic pole, between a first end and a second end so that the distance between the axis of rotation and the first end of the constant segment is equal to the distance between the axis of rotation and the second end of the constant segment which is closer to the free end 30 of said magnetic pole than the first end. This makes it possible to have an area where the outer surface of the rotor extends parallel to the axis of the rotor, that is to say where the distance between the axis of rotation and a point of the constant segment is the same whatever the point taken on said constant segment.
    [0008] This constant segment makes it possible to avoid any throttling zone of the magnetic flux. Advantageously, the constant segment extends axially between an outer axial surface of the flange and the decreasing segment. Where appropriate, the constant segment is closer to the flange than to the free end of the corresponding magnetic pole. This allows that area where the distance between the outer surface of the magnetic pole and the axis of rotation is the same, is in an area where said outer surface is close to the stator and therefore an area where the air gap is low. The current flow of the rotating electrical machine is thus increased. In an advantageous exemplary embodiment, the constant segment is adjacent to the chamfered segment and the decreasing segment. This allows that area where the distance between the outer surface of the magnetic pole and the axis of rotation is the same, is in an area where said outer surface is closest to the stator and therefore an area where the gap is minimal . The current flow of the rotating electrical machine is thus increased. In addition, the constant segment advantageously has a length, in an axial direction, between 0.3 and 0.8 times the length of the outer surface of the corresponding magnetic pole. This constant segment length allows a balancing between the increase of the electric current produced and the good resistance in centrifugation of the rotor. In an advantageous exemplary embodiment, each magnetic pole of only one of the pole wheels has an outer surface 25 comprising, respectively, at least one decreasing segment. The fact that all the magnetic poles of the same pole wheel have the same shape makes it possible to simplify the manufacture of the pole wheel and therefore of the rotor. In another advantageous embodiment, each magnetic pole of the two pole wheels has an outer surface comprising, respectively, at least one decreasing segment. This makes it possible to have a radius of the constant outer surface in a radial plane, over the entire circumference of the rotor, and therefore to improve the performance of this rotor as well as its resistance in centrifugation. Likewise, this makes it possible to have an air gap of the associated rotary electrical machine constant in a radial plane, all around the circumference of said machine, and thus to improve its performance as well as its holding in centrifugation. Advantageously, each magnetic pole is shaped claw. Finally, the present invention relates to a rotating electrical machine comprising a rotor as previously described. Thus, the width of the air gap of the rotating electrical machine is adapted so as to allow both the centrifugation behavior and the improvement of the electromagnetic performance of the corresponding rotating electrical machine, at a given speed. In another configuration, the width of the air gap of the rotating electrical machine is also adapted to allow, for a given centrifugation strength and for a given airgap width, the increase in the speed of rotation of the rotor. thus makes it possible to improve the performance of the rotating electrical machine. In addition, a rotating electrical machine as previously described may advantageously form an alternator or an alternator-starter. The invention will be better understood on reading the detailed description which follows, examples of non-limiting implementation of the invention and the examination of the accompanying drawings, in which: - Figure 1 represents, schematically and partially, a sectional view of a rotary electric machine according to an exemplary implementation of the invention; - Figure 2 shows, schematically and partially, a sectional view of a rotor and a stator of the figure 1, - Figure 3 shows, schematically and partially, a sectional view of a portion of a rotor and a stator according to another embodiment. Identical, similar or similar elements retain the same references from one figure to another.
    [0009] 1 shows a rotating electrical machine 1 compact and polyphase, especially for a motor vehicle. This rotating electrical machine 1 transforms mechanical energy into electrical energy, into alternator mode, and can operate in starter mode 5 to transform electrical energy into mechanical energy. 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 10 the radial, transverse and axial orientations are to be considered with respect to this axis X. In this example, the casing 2 comprises a front bearing. 6 and a rear bearing 7 which are assembled together. These bearings 6, 7 are hollow in shape and each carries, 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 makes it possible to transmit the rotational movement to the shaft 3.
    [0010] The rear end of the shaft 3 carries, here, slip rings belonging to a collector and connected by wire links to the winding. 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.
    [0011] The front bearing 6 and the rear bearing 7 may furthermore 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 front fan 13 on the front dorsal face of the rotor 4, that is to say at the front bearing 6 and 30 of a rear fan 14 on the rear dorsal face of the rotor, that is to say at the 7. In this 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 notch insulation for the assembly of the phases of the stator. Each phase comprises at least one winding 16 passing through the notches of the body 15 and forming, with all the phases, a front bun and a rear bun on either side of the body of the stator. The windings 16 are obtained, for example, from a continuous wire covered with enamel or from bar-like conductor elements such as pins connected together. These windings 16 are, for example, three-phase windings connected in a star or in a triangle, the outputs of which are connected to the rectifier bridge 9.
    [0012] The rotor 4 of Figure 1 is a claw rotor. It comprises two pole wheels 17. Each pole wheel 17 is formed of a flange 18 and a plurality of magnetic poles 19. The rotor 4 further comprises a cylindrical core 20 which is interposed axially between the pole wheels 17. Here, this core 17 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 magnetic poles 19, a coil 21 comprising, here, a winding hub and an electric winding on this hub. The coil 21 may be wound on a coil insulator 22.
    [0013] The rotor 4 may also comprise permanent magnets (not shown) interposed between two adjacent magnetic poles 19 at the outer periphery of the rotor. Alternatively, the rotor 4 may be devoid of such permanent magnets. When the electric winding is electrically powered from the brushes, the rotor 4 is magnetized and becomes an inductor rotor with formation of magnetic north-south poles at the magnetic poles 19. This inductive rotor creates an alternating induced current in the induced stator. when the shaft 3 is rotating. The rectifier bridge 9 then transforms this AC induced current into a DC current, in particular for supplying the loads and the consumers of the onboard network of the motor vehicle as well as for recharging its battery. Figure 2 illustrates more specifically one of the pole wheels 17 of the rotor 4 of Figure 1. The pole wheel 17 has a flange 18 of transverse orientation. The flange 18 has, here, an annular shape defined by an outer axial surface 25 extending substantially perpendicular to the axis X and an inner axial surface 23 extending substantially perpendicular to the axis X.
    [0014] The pole wheel 17 has, in addition, a plurality of magnetic poles 19. The magnetic poles 19 are each preferably trapezoidal in shape and in particular in the form of a claw. Each of the magnetic poles 19 extends in a substantially axial direction from the flange 18 to a free end 26 of the corresponding magnetic pole 19. The magnetic poles 19 of a pole wheel are, respectively, directed axially towards the flange 18 of the other pole wheel, each magnetic pole 19 penetrating into the space between two magnetic poles neighboring said other pole wheel, so that the magnetic poles 19 of the two pole wheels 17 are interleaved. Each magnetic pole 19 has an outer surface 27 opposite the stator 5 and an inner surface 28 radially opposite to said outer surface 27. The outer surface 27 and the inner surface 28 extend substantially axially, respectively.
    [0015] The outer surface 27 of each of the magnetic poles 19 extends substantially axially between the outer axial surface 25 of the flange 18 and the free end 26. The outer surface 27 of the magnetic pole 19 of the pole wheel 17 has a decreasing segment 29 configured so that a radius between the outer surface 27 and the X axis of the rotor 4 decreases, as one moves, along the decreasing segment 29, toward the free end 26 of the corresponding magnetic pole 19 . For example, the distance between the X axis and the outer surface 27 at the free end 26 is less than the distance between the X axis and the outer surface 27 at one end of the decreasing segment 29 opposite , axially, at the free end 26. In this case, one end of the decreasing segment 29 is merged with the free end 26.
    [0016] In the embodiment of FIG. 2, the inner surface 28 has a segment configured so that a radius between the inner surface 28 and the X axis of the rotor 4 increases when the moving along the segment toward the free end 26 of the magnetic pole 19 5 corresponding. In an alternative embodiment, this segment could be configured so that a radius between the inner surface 28 and the X axis of the rotor 4 is constant, as one moves along the segment towards the free end 26 of the magnetic pole 19 corresponding. In the two configurations described above, the free end 26 of the magnetic pole 19 is the portion of said magnetic pole which has a minimum radial width. In addition, the outer surface 27 is closer to the axis X at the free end 26 than at the portion of the magnetic pole 19 near the flange 18 and thus further away from the stator 5. In the example Shown here, the radius of the outer surface 27 decreases along the decreasing segment 29 in a substantially linear fashion. As a variant, this radius could decrease by forming bearings, for example in the form of a staircase. In another variant embodiment, this radius could also decrease by following a curve shape, for example an ellipse.
    [0017] Preferably, the radius of the outer surface 27 decreases, along the decreasing segment 29, at an angle less than or equal to 20 ° with respect to the axis X. Still preferably, this angle is greater than 0.1 ° . In addition, the decreasing segment 29 preferably has a length, in an axial direction, between 0.2 and 1 times the axial length of the outer surface 27 of the corresponding magnetic pole 19. In this example, the outer surface 27 further comprises a chamfered segment 24 extending from the outer axial surface 25 of the flange 18. In the example of FIG. 2, the descending segment 29 extends over the length of the outer surface 27 between the chamfered segment 24 and the free end 26. FIG. 3 illustrates another embodiment of the rotor wheel 17 of the rotor 4. In this embodiment, the outer surface 27 has a 3037198 n further, a constant segment 30 configured so that the radius between the outer surface 27 and the axis X of the rotor 4 is constant along the constant segment 30. Preferably, the constant segment 30 extends axially between the outer axial surface 25 of the flange 18 and the descending segment 29. In particular, in the example represented here, the constant segment 30 is adjacent to the chamfered segment 24 and to the decreasing segment 29. Preferably, the constant segment has a length, in an axial direction, between 0.3 and 0.8 times the length of the outer surface 27 of the corresponding magnetic pole 19. By choosing such a ratio, for each magnetic pole 19, the constant segment 30 is sized as a function of the total flux transferred by the magnetic pole from the rotor 4 to the stator 5 since the length of the magnetic pole 19 is dimensioned to transfer this flux. In addition, this ratio is chosen taking into account the reluctance of the magnetic circuit of the magnetic pole. Thus, in the example of FIG. 3, the outer surface 27 of the magnetic pole 19 comprises a chamfered segment 24, a constant segment 30 and a decreasing segment 29. In a variant, the outer surface 27 could comprise several constant segments 30 and or a plurality of decreasing segments 29, alternately arranged in the length of the outer surface 27 in one embodiment. In one embodiment, each magnetic pole 19 of the pole wheel 17 has an outer surface 27 as previously described. In addition, in another embodiment, each magnetic pole 19 of the two pole wheels 17 of the rotor 4 has an outer surface 27 as previously described. Such an outer surface 27 of a rotor 4 can be formed directly during the manufacturing process of the pole wheel 17. In an alternative embodiment, this form of outer surface 27 can be machined once the rotor 4 has been formed. In both cases, the outer surface 27 is formed before the package of the rotor 4.
    [0018] The present invention further relates to a rotary electric machine 1, such as an alternator or an alternator-starter, comprising a rotor 4 as previously described. The fact that the outer surface 27 of the magnetic pole 19 has a decreasing segment 29 allows the rotary electric machine 1 to have an air gap 31 which has a width, in a radial direction, which increases when moving axially. towards the free end 26 of said magnetic pole 19. An air gap 31 is defined as a space between an inner surface 32 of the stator 5, corresponding to the inner axial periphery 10 of said stator 5, and the outer surface 27 of one of the poles. The inner surface 32 and the outer surface 27 extend axially and are facing each other. Thus, the width of the gap 31 varies. In particular, the width of the air gap 31 at the free end 26 is greater than the width of the gap 31 at the zone of the magnetic pole 19 close to the flange 18. The gap 31 is therefore at the free end 26 of the magnetic pole 19. In addition, the passage of the magnetic flux from the rotor 4 to the stator 5 is very important in the zone of the magnetic pole 19 near the flange 18.
    [0019] Thus, reducing the air gap 31 in this flow passage zone generally makes it possible to substantially increase the flow passage from the rotor 4 to the stator 5, for a given speed of rotation. This is all the more advantageous as the zone of the free end 26 of each magnetic pole 19 is the zone most sensitive to the centrifugal effect generated by the rotation of the rotor 4. Thus, increasing the gap 31 in the zone of the free end 26 of the magnetic pole 19 makes it possible to substantially increase the speed of rotation of the rotor 4 without increasing the risk of friction between the rotor 4 and the stator 5. The electric current produced, in particular the level current flow, as well as the mechanical performance of such a rotating electrical machine 1 are greatly improved. Indeed, such a rotating electrical machine can then achieve rotational speeds of the rotor greater than 20,000 revolutions per minute (rpm) and in particular of the order of 23,800 rpm without damaging said machine. For rotary electric machine applications at speeds less than 20,000 rpm, the present invention can make it possible to increase the length of the magnetic pole comprising such an outer surface. Indeed, the free end of the magnetic pole being further away from the stator, the constraints on the centrifugation effect of said magnetic pole are reduced. Thus, the length of the magnetic pole can be increased to improve the electromagnetic performance of the rotor.
    [0020] In addition, for the same reasons, the axial thickness of the flange of the pole wheel can be reduced and thus allow the rotor to have a larger amount of wound conductors, for applications at speeds below 20,000 rpm. In addition, the present invention makes it possible to provide a rotor for a rotating electrical machine in a simple, reliable, inexpensive and efficient manner while improving its performance. The invention finds applications in particular in the field of rotors for alternator or alternator-starter but it could also be applied to any type of rotating electrical machine 20 comprising a rotor, in particular a claw rotor. Of course, the foregoing description has been given by way of example only and does not limit the scope of the invention which would not be overcome by replacing the different elements by any other equivalent.
