te sur sa face tournée vers le rotor., une forme 2 adaptée à l'arrondi du rotor comme représenté à la figure 1. La figure 1 représente la vue de dessus à partir de la face frontale de l'empilage de tôles du stator vers l'élément de couverture 1. La figure 1 montre encore que l'élément de couverture 1 est inséré entre les pointes des deux pôles 3 et 4 et te on its face turned towards the rotor., a shape 2 adapted to the rounding of the rotor as shown in FIG. 1. FIG. 1 represents the top view from the front face of the stack of sheets of stator towards the covering element 1. FIG. 1 also shows that the covering element 1 is inserted between the points of the two poles 3 and 4 and

L'élément de couverture 1 dépasse au moins d'une face frontale de l'empilage de tôles sur sa longueur. Le côté de l'élément de couverture 1, opposé à l'enceinte du rotor, présente un grand nombre de raidisseurs 5 qui sont dirigés suivant l'axe du moteur et qui vont jusqu'à toucher i'empilage de tôles, tandis que des raidisseurs 6 plus étroits sont disposés perpendiculairement au premier, mais qui ne ferment qu'une faible partie des canaux formés par les raidisseurs 5, de sorte qu'il reste possible de faire passer par exemple des conducteurs à travers les canaux. La figure 2 montre plus particulièrement la disposition des raidisseurs. Les canaux formés par les raidisseurs servent de logement à des connecteurs à fiche 7 sur une face frontale de l'élément de couverture 1. Les connecteurs à fiche 7 et leur mode de fixation dans l'élément de couverture 1 sont représentés à la figure 3.. La figure 3 représente une coupe de l'extrémité de l'élément de couverture située en haut à la figure. Le connecteur à fiches 7 en forme de U présente de préférence une languette 8 obtenue par pliage et découpage, sur laquelle peut être appliquée l'extrémité d'un enroulement de bobine de manière à conduire l'électricité. L'extrémité 9 du connecteur à fiche est de préférence une languette de prise sur laquelle peut être placé un connecteur à fiche qui est relié à un cordon menant à des The covering element 1 protrudes at least from one end face of the sheet stack along its length. The side of the covering element 1, opposite the enclosure of the rotor, has a large number of stiffeners 5 which are directed along the axis of the engine and which go as far as touching the stack of sheets, while narrower stiffeners 6 are arranged perpendicular to the first, but which only close a small part of the channels formed by the stiffeners 5, so that it remains possible for example to pass conductors through the channels. Figure 2 shows more particularly the arrangement of the stiffeners. The channels formed by the stiffeners serve as housing for plug connectors 7 on a front face of the cover element 1. The plug connectors 7 and their method of fixing in the cover element 1 are shown in FIG. 3 .. Figure 3 shows a section of the end of the cover element located at the top in the figure. The U-shaped plug connector 7 preferably has a tongue 8 obtained by folding and cutting, to which the end of a coil winding can be applied so as to conduct electricity. The end 9 of the plug connector is preferably a plug tab on which can be placed a plug connector which is connected to a cord leading to

La position des connecteurs à fiche 7 est encore montrée à la figure 1 o les connecteurs sont The position of the plug connectors 7 is also shown in Figure 1 o the connectors are
260457C260457C
représentés & partir de la face -frontale du moteur, et à la figure 2 o on les voit à partir du côté extérieur du moteur. Sur l'élément de couverture 1 il est encore prévu des ergots 12 dont le nombre et la forme peuvent être différents et qui servent à la fixation au moins provisoire des extrémités de l'enroulement du moteur, mais qui d'une manière avantageuse peuvent être utilisés pour guider, maintenir le fil et relâcher en permanence la tension. La figure 1 montre encore qu'une thermosonde 13 peut être avantageusement montée dans l'un des canaux formés par les raidisseurs 5. Il est possible aussi de monter des bobines de self, des composants électroniques ou composants similaires introduits et maintenus dans'les canaux 'fournis par les raidisseurs 5. La réalisation d'un moteur conformé suivant l'invention est la suivante: la bobine est tout d'abord enroulée sur le noyau de pôle, ensuite les extrémités des enroulements sont fixées par un élément particulier de la bobineuse, l'élément de couverture 1 est ensuite introduit dans le stator entre les pointes des pôles et enfin les extrémités des enroulements sont libérées par la bobineuse pour être fixées sur les connecteurs à fiche 7 et/ou shown & from the -front face of the engine, and in Figure 2 o we see them from the outside of the engine. Lugs 12 are also provided on the covering element 1, the number and shape of which can be different and which serve for at least temporary fixing of the ends of the motor winding, but which advantageously can be used to guide, hold the thread and permanently release tension. FIG. 1 also shows that a thermoprobe 13 can advantageously be mounted in one of the channels formed by the stiffeners 5. It is also possible to mount inductor coils, electronic components or similar components introduced and maintained in the channels 'supplied by the stiffeners 5. The embodiment of a motor shaped according to the invention is as follows: the coil is first wound on the pole core, then the ends of the windings are fixed by a particular element of the winder , the covering element 1 is then introduced into the stator between the points of the poles and finally the ends of the windings are released by the winder to be fixed on the plug connectors 7 and / or
auparavant sur les ergots 12.previously on the pins 12.
L'invention a pour avantage de permettre la réalisation entièrement automatique et en une seule opération de l'enroulement avec ses raccordements, de telle sorte que le moteur puisse être raccordé également entièrement automatiquement au moyen d'un The invention has the advantage of allowing the fully automatic and in a single operation of the winding with its connections, so that the motor can also be connected fully automatically by means of a
manipulateur, aux câbles menant à l'appareil. manipulator, to cables leading to the device.
Ce mode de réalisation du moteur est rendu possible de manière avantageuse en ce que les connecteurs à fiche sont disposés directement sur l'élément de couverture et en ce que ce dernier est calé avec certitude entre les pointes des pôles du This embodiment of the motor is advantageously made possible in that the plug connectors are arranged directly on the cover element and in that the latter is wedged with certainty between the points of the poles of the
