La figure 1 illustre schematiquement l'extremite avant d'un vehicule automobile qui comprend un ensemble 1 comprenant lui-meme un echangeur de chaleur 2 et un ventilateur 3. Le ventilateur 3 comprend un moteur electrique 4 et FIG. 1 schematically illustrates the front end of a motor vehicle which comprises an assembly 1 itself comprising a heat exchanger 2 and a fan 3. The fan 3 comprises an electric motor 4 and
une helice 5 montee sur une arbre de sortie 6 du moteur 4. a propeller 5 mounted on an output shaft 6 of the motor 4.

Toutefois, le ventilateur 3 peut en variante In FIG. 1, the fan 3 has been placed at the rear of the radiator 2, that is to say in the suction configuration. However, the fan 3 can alternatively
etre dispose a ['avant du radiateur 2, c'est a dire en configuration soufflante. be placed at the front of the radiator 2, that is to say in the fan configuration.
Le moteur 4 est un moteur electrique a courant continu qui est raccorde electriquement a une source d'alimentation electrique 8 le soumettant a une tension d'alimentation U. par exemple de 42 Volts, et de maniere plus The motor 4 is a direct current electric motor which is electrically connected to an electric power source 8 subjecting it to a supply voltage U. for example of 42 Volts, and more
generale comprise entre 30 et 50 Volts, voire entre 36 et 42 Volts. general between 30 and 50 Volts, or even between 36 and 42 Volts.
Une telle source 8 peut comprendre un alternateur, ou une batterie delivrant directement la tension U. ou une batterie de 12 Volts suivie d'un convertisseur de tension Comme cela est connu, le moteur 4 comprend un stator inducteur 10 et un rotor induit 12 solidaire en rotation de l'arbre de sortie 6 et entoure Such a source 8 may include an alternator, or a battery directly delivering the voltage U. or a 12-volt battery followed by a voltage converter As is known, the motor 4 comprises an inductor stator 10 and an induced rotor 12 integral in rotation of the output shaft 6 and surrounds
exterieurement par le stator 10.externally by stator 10.
Comme represente sur la figure 2 en pointilles, le stator 10 definit successivement peripheriquement six poles magnetiques 14 alternes. Ces poles As shown in Figure 2 in dotted lines, the stator 10 successively peripherally defines six magnetic poles 14 alternating. These poles
14 peuvent etre par exemple formes par des aimants permanents. 14 may for example be formed by permanent magnets.
Comme cela est connu, le rotor 12 comprend un corps magnetique muni de dents 16 s'etendant radialement par rapport a l'axe de rotation A et delimitant entre elles des encoches 18. Dans l'exemple represente, le rotor 12 As is known, the rotor 12 comprises a magnetic body provided with teeth 16 extending radially with respect to the axis of rotation A and delimiting between them notches 18. In the example shown, the rotor 12
comprend vingt dents 16 et vingt encoches 18. includes twenty teeth 16 and twenty notches 18.
Le rotor 12 porte un enroulement electriquement conducteur 20 comprenant des fils electriquement conducteurs 22 raccordes electriquement aux The rotor 12 carries an electrically conductive winding 20 comprising electrically conductive wires 22 electrically connected to the
lames 24 d'un collecteur 26.blades 24 of a collector 26.
Le collecteur 26 comprend vingt lames 24 dans l'exemple represente. The collector 26 comprises twenty blades 24 in the example shown.
Le collecteur 26 est porte par le rotor 12 pour tourner avec lui autour de l'axe A. Le moteur 4 comprend en outre deux padres de balais 28 qui restent fixes lorsque le rotor 12 tourne autour de l'axe A. Les balais 28 vent raccordes electriquement a la source d'alimentation electrique 8 et viennent frotter sur les The collector 26 is carried by the rotor 12 to rotate with it around the axis A. The motor 4 further comprises two padres of brushes 28 which remain fixed when the rotor 12 rotates around the axis A. The brushes 28 wind electrically connected to the electrical power source 8 and rub on the
lames 24 du collecteur 26 pour alimenter electriquement l'enroulement 20. blades 24 of the collector 26 for electrically supplying the winding 20.
L'enroulement 20 ainsi alimente est alors soumis, comme cela est connu, du fait du champ magnetique cree par le stator 14, a des forces magnetiques The winding 20 thus supplied is then subjected, as is known, due to the magnetic field created by the stator 14, to magnetic forces
provoquant la rotation du rotor 12 et done de lthelice 5. causing the rotor 12 and therefore the propeller 5 to rotate.
Conformement a ['invention, I'enroulement 20 est un enroulement ondule. Plus specifiquement, I'enrou lement 20 du mode de real isation d es According to the invention, the winding 20 is a wavy winding. More specifically, the winding 20 of the embodiment of the
figures 1 a 3 est un enroulement ondule simple. Figures 1 to 3 is a simple wavy winding.
s Le motif elementaire d'un tel enroulement est illustre par la figure 3 ou l'on volt la forme d'un fil electriquement conducteur 22, et le debut du fil electriquement conducteur 22 suivant. Chaque fil 22 est connecte par ses deux extremites au collecteur 26. Chaque fil 22 correspond au motif elementaire de l'enroulement. Le motif elementaire a sensiblement une forme d'hexagone dont s The elementary pattern of such a winding is illustrated in FIG. 3 where the shape of an electrically conductive wire 22 is shown, and the beginning of the following electrically conductive wire 22. Each wire 22 is connected by its two ends to the collector 26. Each wire 22 corresponds to the elementary pattern of the winding. The elementary pattern has substantially a hexagon shape whose
les deux cOtes inferieurs ont ete ouverts. the two lower sides have been opened.
Sur la figure 2, on a represente en gras une serie de trots conducteurs In Figure 2, there is shown in bold a series of trotting conductors
22 successifs. Au sens de la presente description, deux conducteurs 22 vent 22 successive. Within the meaning of this description, two conductors 22 wind
successifs lorsqu'ils possedent chacun une extremite raccordee a la meme lame 24. Comme on peut le constater, deux conducteurs 22 successifs ne se coupent pas geometriquement et les zones geometriques qutils delimitent chacun interieurement ne se chevauchent pas partiellement, contrairement au cas des successive when they each have an end connected to the same blade 24. As can be seen, two successive conductors 22 do not intersect geometrically and the geometric zones which they each delimit internally do not overlap partially, unlike in the case of
enroulements imbriques.interlocking windings.
- La structure d'un tel enroulement imbrique est illustree par la figure 4 ou deux conducteurs 22 successifs vent representes. Comme on le volt sur cette figure, le motif elementaire qui correspond a un fil 22, a sensiblement une forme d'hexagone. Les deux conducteurs 22 successifs se coupent geometriquement et les zones geometriques qu'ils delimitent interieurement se chevauchent partiellement. L'epaisseur axiale des chignons 30 formes a chaque extremite axiale du rotor 12 par les trongons 32 des fils 22 qui ne vent pas loges dans les encoches 18 est reduite par rapport aux moteurs de l'etat de la technique. Ceci est dD au fait que ces tron,cons 32, dits tron,cons inactifs, vent plus courts en - The structure of such a nested winding is illustrated in Figure 4 or two successive conductors 22 wind represented. As shown in this figure, the elementary pattern which corresponds to a wire 22 has substantially the shape of a hexagon. The two successive conductors 22 intersect geometrically and the geometric zones which they delimit internally partially overlap. The axial thickness of the buns 30 formed at each axial end of the rotor 12 by the lengths 32 of the wires 22 which do not wind housed in the notches 18 is reduced compared to the motors of the state of the art. This is due to the fact that these sections, cons 32, known as sections, inactive cons, wind shorter in
raison du nombre de poles 14 plus important. because of the higher number of poles 14.
Ainsi, la longueur axiale du moteur 4 et done de ['ensemble 1 est reduite. Pour autant, le moteur 4 ne comporte, grace a l'utilisation d'un enroulement 20 ondule, que deux padres de balais 28, ce qui permet de Thus, the axial length of the motor 4 and therefore of the assembly 1 is reduced. However, the motor 4 comprises, thanks to the use of a winding 20 undulates, only two padres of brushes 28, which allows
conserver un coOt reduit.keep a reduced cost.
Enfin, I'utilisation d'une tension d'alimentation relativement elevee permet d'avoir un diametre de fils 22 suffisamment faible pour pouvoir menager des encoches 18 dans le rotor 12, ce qui ne serait pas possible avec une tension habituelle de liordre de 10 ou 18 Volts et un enroulement ondule tel que celui de ['invention. Par ailieurs, I'utilisation d'un enroulement 20 ondule permet, a puissance egale de moteur 4, de limiter le temps necessaire pour bobiner les fils 22 afin de realiser l'enroulement 20. De plus, les courants de circulation apparaissant dans l'enroulement 20 lors du fonctionnement du moteur vent reduits. Dans une variante illustree par la figure 5, I'enroulement 20 est un enroulement ondule en faisceau. Plus specifiquement, il s'agit d'un enroulement ondule triple, c'est a dire que chaque motif elementaire ou conducteur 22 forme Finally, the use of a relatively high supply voltage makes it possible to have a wire diameter 22 sufficiently small to be able to arrange notches 18 in the rotor 12, which would not be possible with a usual voltage of the order of 10 or 18 Volts and a winding undulates like that of the invention. Furthermore, the use of a corrugated winding 20 makes it possible, at equal power from motor 4, to limit the time necessary to wind the wires 22 in order to produce the winding 20. In addition, the circulation currents appearing in the winding 20 during operation of the wind motor reduced. In a variant illustrated by FIG. 5, the winding 20 is a wavy bundle winding. More specifically, it is a triple wavy winding, that is to say that each elementary or conductive pattern 22 forms
deux boucles hexagonales entre ses deux extremites. two hexagonal loops between its two ends.
De maniere plus generale d'autres enroulements ondules en faisceaux peuvent etre utilises, par exemple des enroulements doubles, c'est a dire formant une boucle dans cheque motif elementaire. L'utilisation d'enroulements 20 ondules en faisceaux permet de limiter les problemes lies a la commutation, et notamment l'usure des balais 28, car le nombre de lames 24 peut alors etre More generally, other corrugated windings in bundles can be used, for example double windings, that is to say forming a loop in each elementary pattern. The use of windings 20 corrugated in bundles makes it possible to limit the problems linked to switching, and in particular the wear of the brushes 28, because the number of blades 24 can then be
superieur au nombre d'encoches.greater than the number of notches.
