Description

L'invention concerne notamment un dispositif de démarrage pour moteur à combustion interne, notamment de véhicule automobile, et plus particulièrement un démarreur "compound", c'est-à-dire un démarreur composé d'un ensemble de bobines connectées en série avec l'induit et d'un ensemble de bobines connectées en parallèle avec l'induit (bobines shunts).The invention relates in particular to a starting device for an internal combustion engine, in particular a motor vehicle, and more particularly to a "compound" starter, that is to say a starter composed of a set of coils connected in series with the motor. armature and a set of coils connected in parallel with the armature (shunt coils).

On connaît par le brevet FR 2 174 421 un contacteur électromagnétique pour démarreur électrique de véhicule automobile. Ce contacteur comprend un équipage mobile composé d'un noyau plongeur sur lequel est fixé une tige portant à l'une de ses extrémités une plaquette de contact montée coulissante. Cette plaquette est initialement en appui, notamment par l'action de ressorts, sur des contacts d'un circuit électrique comprenant une résistance de bobinage de sorte que, dans une première phase de démarrage, le démarreur tourne à faible vitesse. Dans une deuxième phase de démarrage, cette même plaquette de contact ferme un circuit électrique permettant au démarreur de délivrer son couple maximum.We know by the patent FR 2 174 421 an electromagnetic contactor for a motor vehicle electric starter. This contactor comprises a mobile unit composed of a plunger core on which is fixed a rod carrying at one of its ends a sliding mounted contact plate. This plate is initially supported, in particular by the action of springs, on contacts of an electrical circuit comprising a winding resistor so that, in a first startup phase, the starter rotates at a low speed. In a second start-up phase, this same contact plate closes an electrical circuit allowing the starter to deliver its maximum torque.

Le brevet FR 2 827 341 décrit un contacteur électromagnétique avec une résistance de puissance pour permettre une pré-rotation du lanceur.The patent FR 2 827 341 describes an electromagnetic contactor with a power resistor to allow pre-rotation of the launcher.

La demande de brevet FR 2 881 479 décrit un dispositif de commande d'un démarreur doté d'un moteur électrique. Celui-ci comprend un bobinage inducteur à quatre enroulements formant deux groupes en parallèle chacun de deux enroulements en série. Un interrupteur électromagnétique à action différée est prévu pour permettre, dans une première phase, l'activation seulement de l'un des groupes d'enroulements et, dans une deuxième phase, l'activation des deux groupes d'enroulements.The patent application FR 2 881 479 describes a control device of a starter with an electric motor. This comprises an inductor winding with four windings forming two groups in parallel each of two windings in series. A deferred electromagnetic switch is provided to allow, in a first phase, the activation of only one of the groups of windings and, in a second phase, the activation of the two groups of windings.

On a représenté sur la figure 2 différents éléments d'un dispositif de démarrage selon un état de la technique.We have shown on the figure 2 different elements of a starting device according to a state of the art.

Parmi ces éléments, figure un contacteur principal P relié, d'une part, à une batterie 26 et, d'autre part, à un bobinage inducteur B formé par une pluralité de bobines en série. Ces bobines ont la même résistance électrique.Among these elements, there is a main contactor P connected, on the one hand, to a battery 26 and, on the other hand, to an inductor coil B formed by a plurality of coils in series. These coils have the same electrical resistance.

D'une manière générale, lors du démarrage (le contacteur P étant dans l'état ON comme illustré sur la courbe a/ de la figure 3), il se produit aux bornes de la batterie, pendant l'appel, une chute de tension (voir courbe b/ de la figure 3). Cette chute peut par exemple entraîner la tension jusqu'à une valeur en dessous de 9 Volts.In general, when starting (the switch P being in the ON state as illustrated on the curve a / of the figure 3 ), there is a voltage drop across the battery terminals during the call (see curve b / figure 3 ). This fall can for example cause the voltage to a value below 9 volts.

Toutefois il convient, dans certains cas, d'éviter un niveau de tension excessivement bas aux bornes de la batterie 26 car le réseau de bord du véhicule pourrait être affecté par cette tension trop basse.However, in some cases it is advisable to avoid an excessively low level of voltage at the terminals of the battery 26 because the vehicle's on-board network could be affected by this too low voltage.

L'invention vise notamment à limiter la chute de tension aux bornes de la batterie lors du démarrage sans pour autant dégrader la puissance mécanique délivrée par le dispositif de démarrage.The invention aims in particular to limit the voltage drop across the battery during startup without degrading the mechanical power delivered by the starting device.

L'invention a ainsi pour objet un dispositif de démarrage pour moteur à combustion, notamment de véhicule automobile, comportant :

  • un lanceur agencé pour démarrer le moteur à combustion, notamment par l'intermédiaire d'une couronne,
  • un moteur électrique agencé pour entraîner en rotation le lanceur, le moteur électrique comprenant :
    1. i. un inducteur ou stator comportant un bobinage formé par une pluralité de bobines, l'une au moins des bobines présentant une résistance électrique faible et au moins une autre bobine présentant une résistance électrique forte,
    2. ii. un ensemble de contacteurs agencé pour commander l'alimentation électrique d'une partie seulement des bobines avant de commander l'alimentation électrique de toutes les bobines du bobinage d'inducteur.
The invention thus relates to a starting device for a combustion engine, especially a motor vehicle, comprising:
  • a launcher arranged to start the combustion engine, in particular by means of a crown,
  • an electric motor arranged to drive the launcher in rotation, the electric motor comprising:

    2. ii. a set of contactors arranged to control the power supply of only part of the coils before controlling the power supply of all the coils of the inductor winding.

De préférence, le bobinage d'inducteur comprend au moins une bobine à faible résistance électrique et des première et deuxième bobines à forte résistance, par exemple des premier et deuxième groupes de deux bobines (chacune sur un pôle) à forte résistance, et l'ensemble de contacteurs est agencé pour commander :

  • dans une première phase, l'alimentation électrique de ladite au moins une bobine à faible résistance et de la première bobine à forte résistance électrique, ces bobines étant alors électriquement en série,
  • dans une deuxième phase, l'alimentation électrique essentiellement de la bobine à faible résistance, voire l'alimentation électrique seulement de cette bobine à faible résistance.
Preferably, the inductor winding comprises at least one low-resistance coil and first and second high-resistance coils, for example example of the first and second groups of two coils (each on a pole) with high resistance, and the set of contactors is arranged to control:
  • in a first phase, the power supply of the at least one low resistance coil and the first coil with high electrical resistance, these coils then being electrically in series,
  • in a second phase, the power supply essentially of the low resistance coil, or even the power supply only of this low resistance coil.

Grâce à l'invention, il est possible de réduire fortement la chute de tension lors du pic initial de courant, évitant, le cas échéant, la mise en oeuvre de convertisseur électronique DC/DC coûteux, ou d'une batterie supplémentaire.Thanks to the invention, it is possible to greatly reduce the voltage drop during the initial peak current, avoiding, if necessary, the implementation of expensive DC / DC electronic converter, or an additional battery.

L'invention permet de bénéficier de résistances bobinées de puissance pour temporairement limiter l'appel de courant à un équivalent de tension par exemple égal à 9 Volts aux bornes de la batterie tout en ayant un niveau de couple impulsionnel suffisant à chaud.The invention makes it possible to benefit from power wound resistors for temporarily limiting the current draw to a voltage equivalent, for example equal to 9 volts, across the battery while having a sufficient pulse torque level when hot.

Avantageusement l'ensemble de contacteurs est agencé pour commander :

  • dans une troisième phase succédant aux première et deuxième phases, l'alimentation électrique de toutes les bobines du bobinage d'inducteur.
Advantageously, the set of contactors is arranged to control:
  • in a third phase succeeding the first and second phases, the power supply of all the coils of the inductor winding.

De préférence, la machine comporte un induit ou rotor, et la ou les bobines à faible résistance sont électriquement en série à l'induit de la machine électriquePreferably, the machine comprises an armature or rotor, and the low resistance coil or coils are electrically in series with the armature of the electric machine.

Dans un exemple de mise en oeuvre de l'invention, la machine comporte un induit ou rotor, et la ou les bobines d'inducteur à forte résistance sont électriquement en parallèle à l'induit de la machine électrique lorsque toutes les bobines du bobinage sont alimentées électriquement.In an exemplary implementation of the invention, the machine comprises an armature or rotor, and the high-resistance inductor coil or coils are electrically parallel to the armature of the electrical machine when all the coils of the winding are electrically powered.

Avantageusement le bobinage d'inducteur comporte au moins deux bobines à faible résistance électrique.Advantageously, the inductor winding comprises at least two coils with a low electrical resistance.

De préférence, le bobinage d'inducteur présente deux paires de pôles magnétiques, et les pôles d'un type (par exemple Nord) sont formés par des bobines à faible résistance et les pôles d'un autre type (par exemple Sud) sont formés par des bobines à forte résistance électrique.Preferably, the inductor winding has two pairs of magnetic poles, and the poles of one type (for example North) are formed by low-resistance coils and poles of another type (eg South) are formed by coils with high electrical resistance.

L'invention prévoit ainsi, selon l'un de ses aspects, un dispositif de démarrage avec un stator pourvu d'un ou de plusieurs pôles dits 'shunt' formés par deux sous-bobines à forte résistance de manière à alimenter dans un premier temps une partie seulement des enroulements de ces sous-bobines.The invention thus provides, according to one of its aspects, a starting device with a stator provided with one or more so- called shunt poles formed by two high-strength sub-coils so as to feed initially. only part of the windings of these sub-coils.

Ces parties d'enroulement 'shunt' à alimenter en premier doivent de préférence l'être en série avec l'induit et les pôles inducteur- série à faible résistance, puis doivent être connectés en série avec le reste des enroulements 'shunt' lorsque les bobinages série à faible résistance auront été alimentés par un contacteur dédié commandé avec un certain retard.These 'shunt' winding parts to be fed first should preferably be in series with the armature and low resistance inductor-series poles and then connected in series with the rest of the 'shunt' windings when the Low resistance series windings will have been powered by a dedicated contactor ordered with some delay.

De préférence, l'ensemble de contacteurs comporte au moins un contacteur commandable électriquement.Preferably, the set of contactors comprises at least one electrically controllable contactor.

Avantageusement l'ensemble de contacteurs est agencé de manière à ce que le contacteur principal soit d'abord actionné, puis le premier contacteur auxiliaire et enfin le deuxième contacteur auxiliaire sont actionnés successivement.Advantageously the set of contactors is arranged so that the main contactor is first actuated, then the first auxiliary contactor and finally the second auxiliary contactor are actuated successively.

Si on le souhaite, la bobine à faible résistance électrique comporte au moins un fil électrique présentant un méplat ou une section importante, sur au moins une portion de sa longueur. Eventuellement la bobine à faible résistance comporte un nombre faible de spires.If desired, the low-resistance coil comprises at least one electrical wire having a flat or a large section, over at least a portion of its length. Optionally the low resistance coil has a low number of turns.

Par exemple, la bobine à forte résistance électrique comporte au moins un fil électrique présentant une section transversale plus petite que celle du fil ou des fils de la bobine à faible résistance. Ce fil électrique peut être fin. Eventuellement la bobine à forte résistance comporte un nombre élevé de spires.For example, the high-resistance coil has at least one electrical wire having a smaller cross-section than the wire or wires of the low-resistance coil.

Dans un exemple de mise en oeuvre de l'invention, la bobine à forte résistance électrique comporte un nombre de spires plus grand que pour la bobine à faible résistance.In an exemplary implementation of the invention, the coil with high electrical resistance has a larger number of turns than for the low resistance coil.

Le cas échéant, le dispositif de démarrage est agencé pour redémarrer automatiquement le moteur à combustion.If necessary, the starting device is arranged to automatically restart the combustion engine.

L'invention a encore pour objet un procédé pour démarrer un moteur à combustion, notamment d'un véhicule automobile, à l'aide d'un dispositif de démarrage comportant un moteur électrique pourvu d'un inducteur avec un bobinage comprenant au moins une bobine à faible résistance électrique et des première et deuxième bobines à forte résistance, le procédé comportant les étapes suivantes :

La machine électrique est connectée à une batterie pour son alimentation électrique.The electric machine is connected to a battery for its power supply.

On a représenté sur la figure 1 un dispositif de démarrage 1 pour moteur à combustion interne de véhicule automobile.We have shown on the figure 1 a starting device 1 for an internal combustion engine of a motor vehicle.

Ce dispositif 1 comprend un moteur électrique avec, d'une part, un rotor 2, encore appelé induit, pouvant tourner autour d'un axe X, et d'autre part, un stator 3, encore appelé inducteur, autour du rotor 2.This device 1 comprises an electric motor with, on the one hand, a rotor 2, also called an armature, rotatable about an axis X, and on the other hand, a stator 3, also called an inductor, around the rotor 2.

Ce stator 3 comporte une culasse sur laquelle sont fixées une ou plusieurs pièces polaires 4 pour la mise en place d'un bobinage inducteur 5.This stator 3 comprises a yoke on which are fixed one or more pole pieces 4 for the introduction of an inductor coil 5.

Ce bobinage 5 est décrit en détail plus bas.This winding 5 is described in detail below.

Le rotor 2 comporte un corps de rotor 7, et un bobinage d'induit 8 enroulé dans des encoches du corps de rotor 7.The rotor 2 comprises a rotor body 7, and an armature winding 8 wound in notches of the rotor body 7.

Ce bobinage d'induit 8 forme, de part et d'autre du corps de rotor 7, un chignon avant 9 et un chignon arrière 10.This armature winding 8 forms, on either side of the rotor body 7, a front bun 9 and a rear bun 10.

Le rotor 2 est pourvu, à l'arrière, d'un collecteur 12 comprenant une pluralité de pièces de contact connectées électriquement aux éléments conducteurs, formés dans l'exemple considéré par des fils, du bobinage d'induit 8.The rotor 2 is provided, at the rear, with a collector 12 comprising a plurality of contact pieces electrically connected to the conductive elements, formed in the example in question by wires, of the armature winding 8.

Un groupe de balais 13 et 14 est prévu pour l'alimentation électrique du bobinage d'induit 8, l'un des balais 13 étant relié à la masse du dispositif 1 et un autre des balais 14 étant relié à un contacteur 17. Les balais sont par exemple au nombre de quatre.A group of brushes 13 and 14 is provided for the power supply of the armature winding 8, one of the brushes 13 being connected to the ground of the device 1 and another of the brushes 14 being connected to a switch 17. The brushes are for example four in number.

Les balais 13 et 14 viennent frotter sur le collecteur 12 lorsque le rotor 2 est en rotation.The brushes 13 and 14 rub on the collector 12 when the rotor 2 is rotating.

Le dispositif de démarrage 1 comporte en outre un lanceur 19 monté de manière coulissante sur un arbre d'entraînement 18 et pouvant être entraîné en rotation autour de l'axe X par le rotor 2.The starting device 1 further comprises a launcher 19 slidably mounted on a drive shaft 18 and drivable in rotation about the X axis by the rotor 2.

Un ensemble réducteur de vitesses 20 peut être interposé entre le rotor 2 et l'arbre d'entraînement 18, de manière connue en soi.A gear reduction unit 20 may be interposed between the rotor 2 and the drive shaft 18, in a manner known per se.

Le lanceur 19 comporte un élément d'entraînement formé par un pignon 21 et destiné à s'engager sur un organe d'entraînement 33 du moteur à combustion. Cet organe d'entraînement est par exemple une couronne dentée.The launcher 19 comprises a driving element formed by a pinion 21 and intended to engage on a drive member 33 of the combustion engine. This drive member is for example a ring gear.

Le lanceur 19 comprend en outre une roue libre 22 et une rondelle poulie 23 définissant entre elles une gorge 24 pour recevoir l'extrémité 25 d'une fourchette 27.The launcher 19 further comprises a freewheel 22 and a pulley washer 23 defining between them a groove 24 for receiving the end 25 of a fork 27.

Cette fourchette 27 est réalisée par exemple par moulage d'une matière plastique.This fork 27 is made for example by molding a plastic material.

La fourchette 27 est actionnée par le contacteur 17 pour déplacer le lanceur 19 par rapport à l'arbre d'entraînement 18, suivant l'axe X, entre une première position dans laquelle le lanceur 19 entraîne le moteur à combustion par l'intermédiaire du pignon 21, et une deuxième position dans laquelle le lanceur 19 est désengagé de la couronne dentée 33.The fork 27 is actuated by the switch 17 to move the launcher 19 relative to the drive shaft 18, along the X axis, between a first position in which the launcher 19 drives the combustion engine via the pinion 21, and a second position in which the launcher 19 is disengaged from the ring gear 33.

Le contacteur 17 comprend une borne 29 reliée via un élément de liaison électrique, notamment un fil 30, à une alimentation électrique du véhicule, notamment une batterie 26.The contactor 17 comprises a terminal 29 connected via an electrical connection element, in particular a wire 30, to a power supply of the vehicle, in particular a battery 26.

On va maintenant décrire plus en détail le bobinage inducteur 5.We will now describe in more detail the inductor coil 5.

Comme illustré sur la figure 4, le bobinage inducteur 5 comporte une pluralité de bobines dont des bobines 50 présentant une résistance électrique faible et des premier et deuxième groupes de bobines 51 et 52 présentant une résistance électrique forte.As illustrated on the figure 4 the inductor winding 5 comprises a plurality of coils including coils 50 having a low electrical resistance and first and second groups of coils 51 and 52 having a strong electrical resistance.

Les bobines shunts 51 et 52 sont représentées figure 7 à 10 en deux parties ovales pour les spires nombreuses de faible section (fil rond) et forte résistance caractérisant les bobines shunts, et les bobines séries 50 rectangles pour les spires peu nombreuses de forte section (méplat de section rectangulaire) et faible résistance.The shunt coils 51 and 52 are shown figure 7 to 10 in two oval parts for the numerous rounds of small section (round wire) and strong resistance characterizing the shunt coils, and the series coils 50 rectangles for the few turns of strong section (flat section of rectangular section) and low resistance.

Les bobines shunts 51 et 52 sont connectées à la masse 0 V en parallèle de l'induit 2, et les bobines série 50 connectées en série avec l'induit 2.The shunt coils 51 and 52 are connected to the ground 0 V in parallel with the armature 2, and the series coils 50 connected in series with the armature 2.

Pour 4 pôles, les deux groupes de bobines 50, 51 et 52 qui se distinguent par une différence de résistance électrique très marquée : l'enroulement série à faible résistance, et l'enroulement parallèle (ici double) à forte résistance à des fins de protection thermique. Ce dernier bobinage 51 et 52 ne pouvant naturellement pas bénéficier de la FEM de l'induit 2 lors de la rotation du moteur pour réduire son courant, puisqu'il n'est justement pas en série avec l'induit 2.For 4 poles, the two groups of coils 50, 51 and 52 which are distinguished by a very marked difference in electrical resistance: the low resistance series winding, and the parallel winding (here double) with high resistance for the purpose of thermal protection. This latter winding 51 and 52 can not naturally benefit from the FEM of the armature 2 during the rotation of the motor to reduce its current, since it is not precisely in series with the armature 2.

Une valeur de résistance faible peut par exemple être comprise entre environ 2 à 20 milli- Ohm, et une valeur de forte résistance forte peut par exemple être comprise entre 30 et 300 milli- Ohm, pour par exemple des démarreurs de 12 V.A low resistance value may for example be between about 2 to 20 milli-Ohm, and a strong high resistance value may for example be between 30 and 300 milli-Ohm, for example 12V starters.

Le bobinage inducteur 5 forme deux paires de pôles magnétiques Nord et Sud, et les pôles Nord sont formés par des bobines 50 à faible résistance et les pôles Sud sont formés par des bobines 51 et 52 à forte résistance électrique.The inductor winding 5 forms two pairs of magnetic north and south poles, and the north poles are formed by low resistance coils 50 and the south poles are formed by coils 51 and 52 with high electrical resistance.

Le premier groupe de bobines 51, respectivement le deuxième groupe 52, comporte au moins une bobine 51 a, respectivement 52a, associée à l'un des pôles Sud et au moins une bobine 51 b, respectivement 52b, associée à l'autre des pôles Sud (voir figure 7).The first group of coils 51, respectively the second group 52, comprises at least one coil 51a, respectively 52a, associated with one of the South poles and at least one coil 51b, respectively 52b, associated with the other of the poles. South (see figure 7 ).

L'ensemble 55 de contacteurs comporte un contacteur principal 60 et des premier et deuxième contacteurs auxiliaires 61 et 62.The set 55 of contactors comprises a main contactor 60 and first and second auxiliary contactors 61 and 62.

Habituellement il n'y a qu'un seul contacteur 60 qui sert à tirer sur le levier 27, c'est le contacteur principal. Sur la figure 6 le contacteur principal 60 est le plus gros, car il doit être assez puissant pour pouvoir tirer le levier et pas seulement pousser un contact mobile, il est flanqué de deux contacteurs auxiliaires 61 et 62 plus petits.Usually there is only one switch 60 which is used to pull the lever 27 is the main contactor. On the figure 6 the main switch 60 is the largest, because it must be powerful enough to pull the lever and not just push a movable contact, it is flanked by two auxiliary contactors 61 and 62 smaller.

Le contacteur principal 60, une fois activé, commande ensuite les contacteurs auxiliaires 61 puis 62, qui n'ont pour fonction que de modifier la topologie du circuit électrique, ce qui les différencie encore davantage du principal, qui a pour fonctions de modifier cette topologie, mais aussi, principalement, d'actionner le levier et le lanceur du démarreur avec son pignon.The main contactor 60, once activated, then controls the auxiliary contactors 61 and 62, whose function is only to change the topology of the electrical circuit, which differentiates them even more from the principal, whose function is to modify this topology , but also, mainly, to operate the starter lever and starter with its pinion.

Ces contacteurs 60 à 62 comportent chacun un contacteur 63 et un enroulement de commande 64 de manière à être commandables électriquement.These contactors 60 to 62 each comprise a contactor 63 and a control winding 64 so as to be electrically controllable.

L'ensemble 55 de contacteurs est agencé de manière à ce qu'un courant passant dans l'enroulement 64 du premier contacteur auxiliaire 61 puisse servir à commander l'actionnement du deuxième contacteur auxiliaire 62 avec un retard lié à la constante de temps caractéristique du contacteur 61.The set 55 of contactors is arranged so that a current flowing in the winding 64 of the first auxiliary contactor 61 can serve to control the actuation of the second auxiliary contactor 62 with a delay related to the characteristic time constant of the contactor 61.

L'ensemble 55 de contacteurs est agencé de manière à ce que le contacteur principal 60 soit d'abord actionné, puis le premier contacteur auxiliaire 61 et enfin le deuxième contacteur auxiliaire 62 sont actionnés successivement.The set 55 of contactors is arranged so that the main contactor 60 is first actuated, then the first auxiliary contactor 61 and finally the second auxiliary switch 62 are actuated successively.

On a représenté sur la figure 6 un exemple de disposition des contacteurs 60 à 62, avec les contacteurs auxiliaires 61 et 62 placé de part et d'autre du contacteur principal 60.We have shown on the figure 6 an example of arrangement of the contactors 60 to 62, with the auxiliary contactors 61 and 62 placed on either side of the main contactor 60.

On va maintenant décrire en référence aux figures 7 à 10 différentes étapes de fonctionnement du dispositif de démarrage 1 pour un démarrage du moteur à combustion.We will now describe with reference to Figures 7 to 10 different stages of operation of the starting device 1 for starting the combustion engine.

Etape 1 (figure 7) Step 1 (Figure 7)

Les contacteurs 60 à 62 sont initialement désactivés (la bobine 52 n'est pas alimentée dans cette étape).The contactors 60 to 62 are initially deactivated (the coil 52 is not energized in this step).

Etape 2 (figure 8) Step 2 (Figure 8)

Il se produit, par commande du contacteur principal 60, les contacteurs auxiliaires 61 et 62 étant maintenus désactivés, l'alimentation électrique des bobines 50 à faible résistance et des bobines 51 a et 51 b du premier groupe 51 de bobines à forte résistance électrique, ces bobines étant alors toutes électriquement en série.It produces, by control of the main contactor 60, the auxiliary contactors 61 and 62 being kept off, the power supply of the low resistance coils 50 and the coils 51a and 51b of the first group 51 of coils with high electrical resistance, these coils then being all electrically in series.

Etape 3 (figure 9) Step 3 (Figure 9)

Il se produit, par actionnement des contacteurs 60 et 61, l'alimentation électrique essentiellement des bobines 50 à faible résistance, voire l'alimentation électrique seulement de ces bobines 50 à faible résistance, à l'exclusion des bobines à fortes résistance.It operates, by actuation of the contactors 60 and 61, the power supply essentially of the low-resistance coils 50, or even the power supply only of these low-resistance coils 50, excluding the high-resistance coils.

Etape 4 (figure 10) Step 4 (Figure 10)

Dans cette phase succédant aux phases précédentes, il se produit, par actionnement des trois contacteurs 60 à 62, l'alimentation électrique de toutes les bobines 50, 51 et 52 du bobinage inducteur 5.In this phase following the preceding phases, the electrical power supply of all the coils 50, 51 and 52 of the inductor coil 5 is generated by actuation of the three contactors 60 to 62.

Les bobines d'inducteur à forte résistance 51 et 52 sont alors électriquement en parallèle avec l'induit de la machine électrique lorsque toutes les bobines du bobinage sont alimentées électriquement.The high-resistance inductor coils 51 and 52 are then electrically in parallel with the armature of the electrical machine when all the coils of the winding are electrically powered.

Les bobines à faible résistance 51 et 52 sont électriquement en série avec l'induit 2 de la machine électriqueThe low resistance coils 51 and 52 are electrically in series with the armature 2 of the electrical machine

La machine électrique est connectée à une batterie 26 pour son alimentation électrique.The electric machine is connected to a battery 26 for its power supply.

Lors du démarrage du moteur à combustion à l'aide du dispositif de démarrage 1, la tension aux bornes de la batterie chute tout en restant avantageusement au dessus de 9 Volts.When starting the combustion engine using the starting device 1, the voltage across the battery drops while still advantageously above 9 volts.

Dans un exemple de mise en oeuvre non illustré, il est possible de remplacer chaque groupe de bobines à forte résistance, réparties sur plusieurs pôles, par une seule bobine à forte résistance et localisée sur un seul pôle. Le fonctionnement revient alors à alimenter en 'shunt' un pôle puis les deux.In an example of implementation not illustrated, it is possible to replace each group of high-resistance coils, distributed over several poles, by a single coil with high resistance and located on a single pole. The operation then returns to supply shunt one pole then the two.
