Abstract
Description
"Rotor de machine tournante électrique,
avec encoches logeant deux conducteurs superposés"
La présente invention concerne un rotor de machine tournante électrique, avec encoches logeant deux conducteurs superposés. Plus particulièrement, cette invention concerne la structure des rotors de moteurs électriques à courant continu, avec un paquet de tôles pourvues d'encoches périphériques du type "semi-fermé", recevant chacune deux conducteurs électriques superposés, de section ronde ou autre, appartenant l'un à une couche de conducteurs extérieure et l'autre à une couche de conducteurs intérieure du bobinage."Rotating electric machine rotor,
with slots accommodating two superimposed conductors "
The present invention relates to an electric rotating machine rotor, with slots accommodating two superimposed conductors. More particularly, this invention relates to the structure of the rotors of direct current electric motors, with a package of sheets provided with peripheral notches of the "semi-closed" type, each receiving two superimposed electrical conductors, of round or other cross section, belonging to the one to an outer conductor layer and the other to an inner conductor layer of the winding.
Dans ce genre de rotor, les encoches possèdent un profil de forme oblongue, avec deux côtés rectilignes parallèles s'étendant en direction radiale, et avec deux extrémités arrondies. L'isolement des deux conducteurs introduits dans chaque encoche est assurée au moins partiellement par un vernis d'imprégnation, qui enveloppe les deux conducteurs en remplissant le jeu existant entre ces conducteurs et la paroi de l'encoche. In this type of rotor, the notches have an oblong profile, with two parallel rectilinear sides extending in the radial direction, and with two rounded ends. The isolation of the two conductors introduced into each notch is ensured at least partially by an impregnation varnish, which envelops the two conductors by filling the clearance existing between these conductors and the wall of the notch.
Ce jeu est très variable, car il se limite à un faible interstice vers les extrémités arrondies de l'encoche, alors qu'un jour important existe entre les deux conducteurs et chaque flanc rectiligne de l'encoche. Or le meme vernis d'imprégnation peut difficilement posséder, d'une part, une fluidité suffisante pour pénétrer dans les petits interstices, et d'autre part, une ^/ sc^s té adaptée au remplissage de volumes relativement importants, tels que les jours existant entre les deux conducteurs et les deux flancs de l'encoche. Le profil habituel des encoches ntest donc pas adapté à une bonne imprégnation. This play is very variable, because it is limited to a small gap towards the rounded ends of the notch, while a large day exists between the two conductors and each straight flank of the notch. However, the same impregnating varnish can hardly have, on the one hand, sufficient fluidity to penetrate into small interstices, and on the other hand, a ^ / sc ^ s tee suitable for filling relatively large volumes, such as days existing between the two conductors and the two sides of the notch. The usual profile of the notches is therefore not suitable for good impregnation.
Egalement d'un point de vue thermique, pour l'obtention d'un bon refroidissement des conducteurs du rotor en cours de fonctionnement, le profil actuel des encoches n'est pas idéal, étant donné que l'épaisseur importante du vernis d'imprégnation dans certaines régions constitue un obstacle à la dissipation de la chaleur vers l'extérieur, au travers des tôles du rotor. Also from a thermal point of view, to obtain good cooling of the conductors of the rotor during operation, the current profile of the notches is not ideal, since the large thickness of the impregnation varnish in certain regions constitutes an obstacle to the dissipation of heat towards the outside, through the sheets of the rotor.
La présente invention élimine ces inconvénients, en fournissant un profil d'encoche optimisé. The present invention eliminates these drawbacks by providing an optimized notch profile.
A cet effet, dans le rotor de machine tournante électrique selon
I'invention, le profil de chaque encoche comporte, dans la région médiane de l'encoche, deux becs tournés l'un vers l'autre, formés par les tôles du rotor et s'avançant chacun entre les deux conducteurs, de manière à ménager un jeu sensiblement constant tout autour de ces deux conducteurs.For this purpose, in the rotor of an electric rotating machine according to
I'invention, the profile of each notch comprises, in the middle region of the notch, two spouts facing one another, formed by the sheets of the rotor and each advancing between the two conductors, so as to provide a substantially constant clearance all around these two conductors.
L'invention propose donc un profil d'encoche qui égalise le jeu autour des deux conducteurs superposés logés dans l'encoche, ce qui conduit à un triple résultat
a) Le vernis d'imprégnation n'a plus à satisfaire des exigences contradictoires, en ce qui concerne sa fluidité, pour pouvoir remplir des espaces d'épaisseurs diverses, et la suppression des jours importants entraîne aussi une forte réduction de la quantité totale de vernis nécessaire.The invention therefore provides a notch profile which equalizes the clearance around the two superimposed conductors housed in the notch, which leads to a triple result
a) The impregnation varnish no longer has to meet contradictory requirements, with regard to its fluidity, in order to be able to fill spaces of various thicknesses, and the elimination of important days also results in a large reduction in the total amount of varnish required.
b) Par l'adjonction des deux becs, des épaisseurs habituelles de vernis d'imprégnation se trouvent remplacées par du métal qui est un bon conducteur thermique, et la couche de vernis reste partout relativement fine, de sorte que le refroidissement des conducteurs du rotor se trouve amélioré. b) By the addition of the two nozzles, usual thicknesses of impregnation varnish are replaced by metal which is a good thermal conductor, and the varnish layer remains relatively thin everywhere, so that the cooling of the conductors of the rotor is improved.
c) Les deux becs qui s'avancent entre les deux conducteurs constituent, par ailleurs, des éléments de retenue mécanique pour ces conducteurs. Plus particulièrement, ces becs s'opposent, en cours de fonctionnement, à la force centrifuge s'exerçant sur le conducteur intérieur, sans que celle-ci soit transmise au conducteur extérieur. En outre, les deux becs maintiennent l'écartement géométrique des deux conducteurs, sans solliciter mécaniquement la partie médiane de la capote isolante d'encoche enroulée en "S" autour des deux conducteurs, dans le cas où une telle capote est prévue. c) The two nozzles which extend between the two conductors also constitute mechanical retaining elements for these conductors. More particularly, these spouts oppose, during operation, the centrifugal force exerted on the inner conductor, without this being transmitted to the outer conductor. In addition, the two nozzles maintain the geometrical spacing of the two conductors, without mechanically biasing the middle part of the insulating hood of the notch wound in an "S" shape around the two conductors, in the case where such a hood is provided.
Dans le cas particulier de conducteurs superposés de section ronde, les deux becs possèdent chacun un profil délimité par deux arcs de cercle, dont les concavités sont tournées vers les -axes respectifs des deux conducteurs, de manière à épouser la forme de ces conducteurs. In the particular case of superimposed conductors of round section, the two nozzles each have a profile delimited by two arcs of a circle, the concavities of which face the respective axes of the two conductors, so as to conform to the shape of these conductors.
Dans tous les cas, les becs sont formés directement par un découpage approprié des tôles du rotor, de sorte que l'invention peut être mise en oeuvre de manière extrêmement économique. In all cases, the spouts are formed directly by appropriate cutting of the sheets of the rotor, so that the invention can be implemented in an extremely economical manner.
De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, deux formes d'exécution de ce rotor de machine tournante électrique
Figure 1 est une vue en coupe transversale montrant une encoche d'un rotor conforme à l'invention, avec conducteurs de section ronde
Figure 2 est une vue en coupe similaire à figure 1, mais relative à un rotor avec conducteurs de section différente. In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing showing, by way of nonlimiting examples, two embodiments of this rotor of an electric rotary machine
Figure 1 is a cross-sectional view showing a notch of a rotor according to the invention, with conductors of round section
Figure 2 is a sectional view similar to Figure 1, but relating to a rotor with conductors of different section.
Sur les figures, est représenté un secteur de la périphérie d'un rotor de moteur électrique, dans la région d'une encoche 1 de type "semi-fermé" du paquet de tôles 2. L'encoche 1 sert de logement à deux conducteurs électriques superposés 3 et 4. In the figures, a sector of the periphery of an electric motor rotor is shown, in the region of a notch 1 of the "semi-closed" type of the sheet metal package 2. The notch 1 serves as a housing for two conductors electrical superimposed 3 and 4.
Dans l'exemple de la figure 1, les deux conducteurs 3 et 4 sont de section ronde, et de même diamètre. Ces deux conducteurs 3 et 4 sont enveloppés dans une même capote d'encoche isolante 5, enroulée en "S". In the example of Figure 1, the two conductors 3 and 4 are of round section, and of the same diameter. These two conductors 3 and 4 are wrapped in the same insulating notch cover 5, wound in an "S" shape.
Le profil de l'encoche 1 est déterminé de manière à ménager un jeu de montage 6 de valeur sensiblement constante, tout autour de la capote d'encoche 5. Ainsi, ce profil se définit de la manière suivante
- Le fond de l'encoche 1 possède un profil semi-circulaire 7, coaxial à la section ronde du conducteur inférieur 3.The profile of the notch 1 is determined so as to provide a mounting clearance 6 of substantially constant value, all around the hood of the notch 5. Thus, this profile is defined as follows
- The bottom of the notch 1 has a semi-circular profile 7, coaxial with the round section of the lower conductor 3.
- Dans la région de son entrée 8, l'encoche est délimitée par deux arcs de cercle 9, coaxiaux à la section ronde du conducteur supérieur 4. - In the region of its entry 8, the notch is delimited by two arcs of a circle 9, coaxial with the round section of the upper conductor 4.
- Sur les deux flancs de l'encoche 1, et à mi-profondeur, sont formés deux becs 10 situés l'un en regard de l'autre. Chaque bec 10 s'avance entre les deux conducteurs 3 et 4, en direction de l'autre bec 10. - On the two sides of the notch 1, and at mid-depth, are formed two nozzles 10 located one opposite the other. Each spout 10 advances between the two conductors 3 and 4, in the direction of the other spout 10.
Plus précisément, le profil de chaque bec 10 est délimité par un premier arc de cercle 11, coaxial à la section du conducteur intérieur 3, et par un second arc de cercle 12, coaxial à la section du conducteur extérieur 4, les deux arcs de cercle 11 et 12 se raccordant suivant une pointe légèrement arrondie.More precisely, the profile of each spout 10 is delimited by a first arc of a circle 11, coaxial with the section of the inner conductor 3, and by a second arc of a circle 12, coaxial with the section of the outer conductor 4, the two arcs of circle 11 and 12 connecting along a slightly rounded point.
Les deux becs 10, formés par les tôles 2, remplacent le profil habituellement rectiligne 13 des deux flancs de l'encoche 1. Grâce à la présence de ces becs 10, l'épaisseur du vernis d'imprégnation venant remplir le jeu 6 est sensiblement constante et relativement fine, en tout points. De plus, les deux becs 10 maintiennent l'écartement géométrique des conducteurs 3 et 4, sans solliciter mécaniquement la partie médiane 14 de la capote d'encoche 5 prise en sandwich entre eux. En cours de rotation, la présence des becs 10 a aussi pour effet de répartir les forces centrifuges sur deux zones de réaction, au lieu d'une seule - habituellement: : la force centrifuge appliquée au conducteur intérieur 3 est absorbée par les deux becs supplémentaires 10, tandis que pour la force centrifuge appliquée au conducteur extérieur 4, la réaction est assurée par les deux becs habituels 15 qui délimitent l'entrée 8 de l'encoche 1. The two nozzles 10, formed by the sheets 2, replace the usually rectilinear profile 13 of the two sides of the notch 1. Thanks to the presence of these nozzles 10, the thickness of the impregnation varnish coming to fill the clearance 6 is substantially constant and relatively fine, in all respects. In addition, the two nozzles 10 maintain the geometric spacing of the conductors 3 and 4, without mechanically stressing the middle part 14 of the notch hood 5 sandwiched between them. During rotation, the presence of the spouts 10 also has the effect of distributing the centrifugal forces over two reaction zones, instead of just one - usually: the centrifugal force applied to the inner conductor 3 is absorbed by the two additional spouts 10, while for the centrifugal force applied to the external conductor 4, the reaction is ensured by the two usual nozzles 15 which delimit the inlet 8 of the notch 1.
La figure 2 illustre l'application de l'invention d'une encoche logeant deux conducteurs superposés 3 et 4 de section non pas ronde, mais oblongue. Les éléments correspondants étant désignés par les mêmes repères que sur la figure 1, on note en particulier la présence des deux becs 10 formés sur les flancs de l'encoche 1 à mi-profondeur, et s'avançant l'un vers l'autre entre les deux conducteurs 3 et 4 de section oblongue. FIG. 2 illustrates the application of the invention of a notch housing two superimposed conductors 3 and 4 of section not round, but oblong. The corresponding elements being designated by the same references as in Figure 1, we note in particular the presence of the two nozzles 10 formed on the sides of the notch 1 at mid-depth, and advancing towards one another between the two conductors 3 and 4 of oblong section.
Le rotor objet de l'invention est applicable, entre autres, à la réalisation de démarreurs avec moteur électrique à courant continu, pour le lancement des moteurs à combustion interne, plus particulièrement sur les véhicules automobiles. The rotor object of the invention is applicable, inter alia, to the production of starters with direct current electric motor, for the launch of internal combustion engines, more particularly on motor vehicles.
Il va de soi que l'invention ne se limite pas aux seules formes d'exécution de ce rotor de machine tournante électrique qui ont été décrites ci-dessus, à titre d'exemples ; elle en embrasse, au contraire, toutes les variantes de réalisation et d'application respectant le même principe. C'est ainsi, notamment, que l'invention peut être mise en oeuvre avec des becs 10 de formes et dimensions très diverses, en fonction des sections des deux conducteurs 3 et 4 logés dans chaque encoche 1 du rotor, aucune limitation n'existant quant à la section de ces conducteurs. Bien entendu, l'invention est applicable à un rotor de machine tournante électrique quelconque à double couche de conducteurs, que la machine soit motrice ou génératrice. It goes without saying that the invention is not limited to the sole embodiments of this rotor of an electric rotary machine which have been described above, by way of examples; on the contrary, it embraces all of the variant embodiments and applications respecting the same principle. Thus, in particular, that the invention can be implemented with nozzles 10 of very different shapes and dimensions, depending on the sections of the two conductors 3 and 4 housed in each notch 1 of the rotor, no limitation existing as for the cross section of these conductors. Of course, the invention is applicable to any rotor of an electrical rotary machine with a double layer of conductors, whether the machine is motive or generator.
