Description
Induit de machine électrique.Armature of electric machine.
La présente invention concerne des induits de machines électriques tournantes, notamment de démarreurs pour véhicules automobiles. The present invention relates to armatures of rotating electrical machines, in particular of motor vehicle starters.
Dans les induits de démarreurs connus à ce jour, les conducteurs logés dans les encoches pratiquées dans les tôles, constituant une partie de l'induit, sont disposés les uns au dessus des autres suivant l'axe de l'encoche, quel que soit le nombre de conducteurs par encoche, la forme de la section des conducteurs et le type de l'encoche, c'est à dire encoche ouverte, semi-fermée ou fermée. In the starter armatures known to date, the conductors housed in the notches made in the sheets, constituting a part of the armature, are arranged one above the other along the axis of the notch, whatever the number of conductors per notch, the shape of the conductor cross-section and the type of notch, ie open, semi-closed or closed notch.
Cette disposition des conducteurs présente l'inconvénient d'avoir à réaliser des encoches dont la profondeur provoque un rétrécissement important du fond de la denture, rétrécissement préjudiciable au passage du flux magnétique d'où une certaine limitation des performances de la machine. This arrangement of the conductors has the drawback of having to make notches the depth of which causes a significant narrowing of the bottom of the toothing, a narrowing which is detrimental to the passage of the magnetic flux, hence a certain limitation in the performance of the machine.
La présente invention a pour but de remédier à l'inconvénient cité et concerne à cet effet un induit de machine électrique tour nantie, notamment de démarreur pour véhicules automobiles, induit comprenant des tales munies d'encoches et du type à quatre conducteurs, de section ronde, par encoche caractérisé en ce que les encoches comprenent une première partie consituant le fond de l'encoche, partie dans l'axe de laquelle deux des conducteurs sont disposés sensiblement l'un au dessus de l'autre ; et faisant suite à la première, une deuxième partie dans laquelle les deux autres conducteurs sont disposés de façon telle que la droite joignant'les centres de ces deux conducteurs forme un angle otavec l'axe de l'encoche, de manière que l'augmentation de la section du fond de la denture, due à la diminution de la profondeur de l'encoche, résultant de l'angle 04, améliore les performances du démarreur sons aucun accroissement de ses dimensions. The object of the present invention is to remedy the aforementioned drawback and to this end relates to an armature of a ridden electric machine, in particular a starter for motor vehicles, armature comprising tales provided with notches and of the four-conductor type, of cross section round, by notch characterized in that the notches comprise a first part constituting the bottom of the notch, part in the axis of which two of the conductors are arranged substantially one above the other; and following the first, a second part in which the other two conductors are arranged in such a way that the straight line joining the centers of these two conductors forms an angle ot with the axis of the notch, so that the increase of the bottom section of the teeth, due to the decrease in the depth of the notch, resulting from the angle 04, improves the performance of the starter without any increase in its dimensions.
La description qui va suivre en regard des dessins annexés fera mieux comprendre comment l'invention peut être réalisée. The description which follows with reference to the appended drawings will make it easier to understand how the invention can be implemented.
La figure 1 représente une tôle d'induit de démarreur selon l'art antérieur, l'encoche étant du type ouvert de profondeur L. Figure 1 shows a starter armature sheet according to the prior art, the notch being of the open type of depth L.
La figure 2 représente une tôle d'induit selon l'invention. FIG. 2 represents an armature sheet according to the invention.
Selon un mode préféré de réalisation de l'invention plus particulièrement adapté, mais non exclusivement, à un induit dit "deux spires" chacune des tôles 1 (voir figure 2) constituant le paquet de tôles de l'induit (non représenté) est munie d'une pluralité d'encoches 2, dans lesquelles viennent se loger quatre conducteurs 3a, 3b, 4a, 4b, de section ronde, lesquels conducteurs sont revêtus, de façon connue, d'un émail d'isolement, un papier isolant 5 étant introduit dons l'encoche avant mise en place des conducteurs. According to a preferred embodiment of the invention more particularly, but not exclusively, adapted to an armature known as "two turns" each of the sheets 1 (see FIG. 2) constituting the package of sheets of the armature (not shown) is provided of a plurality of notches 2, in which are housed four conductors 3a, 3b, 4a, 4b, of round section, which conductors are coated, in known manner, with an insulating enamel, an insulating paper 5 being introduces donations before the conductors are put in place.
Chaque encoche 2 comprend une première partie 2a constituant le fond de l'encoche, partie dans l'axe de laquelle les deux conducteurs 3a, 3b sont disposés sensiblement l'un au dessus de l'autre, d'où une hauteur h sensiblement égale à la somme des deux diamètres. Each notch 2 comprises a first part 2a constituting the bottom of the notch, part in the axis of which the two conductors 3a, 3b are arranged substantially one above the other, hence a height h substantially equal to the sum of the two diameters.
Une deuxième partie 2b, faisant suite à la première partie 2a constitue le logement des conducteurs 4a, 4b. A second part 2b, following the first part 2a constitutes the housing of the conductors 4a, 4b.
La forme de cette deuxième partie est judicieusement déterminée de façon telle que lors de l'introduction dans l'encoche des conducteurs 4a, 4b, ceux-ci se placent de manière telle que la droite joignant les centres de ces deux conducteurs forme un angle oi avec l'axe de l'encoche. The shape of this second part is judiciously determined in such a way that during the introduction into the notch of the conductors 4a, 4b, these are placed in such a way that the straight line joining the centers of these two conductors forms an angle oi with the axis of the notch.
De ce fait la hauteur h', suivant l'axe de l'encoche, occupée par les deux conducteurs 4a, 4b, devient très inférieure à la hauteur h des deux conducteurs 3a, 3b, d'où une diminution notable de la profondeur des encoches. As a result, the height h ′, along the axis of the notch, occupied by the two conductors 4a, 4b, becomes much less than the height h of the two conductors 3a, 3b, whence a notable reduction in the depth of the notches.
En conséquence la largeur 1' du fond de la denture est supérieure à la largeur 1 (voir figures 1 et 2) d'une encoche de l'art antérieur, ce qui facilite le passage du flux magnétique dans cette zone et contribue à l'amélioration des performances du démarreur, sans qu'il soit nécessaire d'accroitre ses dimensions. Consequently, the width 1 ′ of the bottom of the teeth is greater than the width 1 (see FIGS. 1 and 2) of a notch of the prior art, which facilitates the passage of the magnetic flux in this area and contributes to the improved starter performance, without the need to increase its dimensions.
