Les enroulements secondaires des moteurs en court-circuit sont normalement constitués de conducteurs actifs soudés à des anneaux d'extrémités et la pratique a prouvé que ce genre de bobinage présentait certains défauts due à l'impossibilité de réaliser une soudure parfaite entre les conducteurs actifs et les anneaux d'extrémités
Les cages ainsi constituées n'ont pas toute la solidité désirable elles présentent aux points de soudure, des résistances iné- vitables et ne pouvant être exactement prédéterminées. En plus, elles demandent une main d'oeuvre importante et expérimentée.
On a remédié a ces inconvénients en coulant d'une pièce les cages de o-ertains moteurs en

la présente invention * pour objet la réalisation d'un bobinage en court-circuit sans soudure et non coule*
Les conducteurs actifs réalises suivant l'invention sont obtenus en partant d'une feuille de métal découpée en son milieu et dépliée sur gaba- rit, de manière à constituer un circuit fermé de caractéristiques déterminées par le moteur à réaliser, la figure 1 représente une telle feuille de métal. La partie A-B Constitua un conducteur actif.

The secondary windings of short-circuited motors are normally made up of live conductors soldered to end rings and practice has shown that this type of winding has certain defects due to the impossibility of achieving a perfect weld between the live conductors and the end rings
The cages thus formed do not have all the desirable strength; they exhibit strengths at the welding points which are unavoidable and which cannot be exactly predetermined. In addition, they require a large and experienced workforce.
These drawbacks have been remedied by casting in one piece the cages of certain engines in

<Desc / Clms Page number 2>
the present invention * for object the realization of a winding in short-circuit without welding and not flowing *
The active conductors produced according to the invention are obtained starting from a sheet of metal cut in the middle and unfolded on a template, so as to constitute a closed circuit with characteristics determined by the motor to be produced, FIG. 1 represents a like sheet of metal. Part A-B Constituted an active conductor.
Part E-F a second active conductor placed in the winding at a distance of one or an odd number of pitches.

laries of the first, Parts B '0, Dt 3 and F. qt R, A constitute the connecting co-conductors having ventilation fins in CD and HG * the final shape of the conductor can be obtained by any machine to open current employee for the manufacture of winding sections. Figure 2 shows the sheet of Fig. 1 opened for a

The sections fit easily into the notches; they are interchangeable and constitute an economical winding and having large cooling surfaces, and causing a movement of air useful for ventilation.
