Description
<EMI ID=1.1>
Le présent brevet consiste en une application au cas

cable aux régime de fonctionnement à vitesse variable en vue d'économiser les pertes dans les résistances de démarrage et de
<EMI ID=4.1>
machine exige que le couple de freinage exercé par la machine électrique, fonctionnant en génératrice, croisse avec la vitesse.
Pour réaliser une vitesse constante et réglable sur différentes pentes, il convient de disposer d'un réseau de caractéristiques telles que I, 2, 3, 4, de la fig. 1 du des in ci-annexé.
<EMI ID=5.1>
Pour réaliser ces conditions, la présente invention prévoit d'opposer deux tensions dans le circuit de l'enroulement indépendant � de l'excitatrice E (voir fig.2).
<EMI ID=6.1>

<EMI ID=7.1>
vitesse. La variation de la tension résultante, donc du courant, est donnée pour chaque valeur de N (voir fig.3) par la résultante
<EMI ID=8.1>
On voit que,pour un cran donné, ai la pente s'annula ce dispositif additionnel permet de passer de la marche en généra-
<EMI ID=9.1>
La diminution de vitesse dépendra de l'inclinaison de la oaractéris-tique compound de la machine. L'inclinaison de oette caracté-
<EMI ID=10.1>
Dans chaque cas particulier, on pourra donc réaliser la f�rme ùe caractéristique qui convient.
Le réseau de caractéristiques peut être obtenu :
<EMI ID=11.1>
s'annule également pour différentes valeurs de N (voir fig.5).
La variation de l'inclinaison ue la caractéristique ooapoud du moteur, en dehors des possibilités de construction, peut encore être obtenue par introduction ou suppression de résistances dans le circuit indépendant [pound] de l'excita-

le brevet principal, fonctionner sur la Caractéristique naturelle, donc en moteur série normal. Mais lorsque l'on veut récupérer, le mécanicien doit changer les connexions réalisées,
<EMI ID=13.1>
vant le schéma de la fig.2.
On peut supprimer oette dernière manoeuvre pour passer en récupération, tout en gardant la même disposition
<EMI ID=14.1>
<EMI ID=15.1>
<EMI ID = 1.1>
The present patent consists of an application to the case
<EMI ID = 2.1> <EMI ID = 3.1>
cable to variable speed operating conditions in order to save losses in starting resistors and
<EMI ID = 4.1>
machine requires that the braking torque exerted by the electric machine, operating as a generator, increases with speed.
To achieve a constant and adjustable speed on different slopes, it is necessary to have a network of characteristics such as I, 2, 3, 4, of fig. 1 of the attached hereto.
<EMI ID = 5.1>
To achieve these conditions, the present invention provides for opposing two voltages in the circuit of the independent winding � of the exciter E (see fig. 2).
<EMI ID = 6.1>
constant, but the current flowing in the independent winding
<EMI ID = 7.1>
speed. The variation of the resulting voltage, and therefore of the current, is given for each value of N (see fig. 3) by the resultant
<EMI ID = 8.1>
We see that, for a given notch, with the slope canceled out, this additional device makes it possible to switch from walking in general.
<EMI ID = 9.1>
The decrease in speed will depend on the inclination of the compound character of the machine. The inclination of this character
<EMI ID = 10.1>
In each particular case, we can therefore achieve the appropriate characteristic.
The network of characteristics can be obtained:
<EMI ID = 11.1>
is also canceled for different values of N (see fig. 5).
The variation of the inclination ue the ooapoud characteristic of the motor, apart from the possibilities of construction, can still be obtained by introducing or removing resistors in the independent circuit [pound] of the exciter.
<EMI ID = 12.1>
the main patent, operate on the natural characteristic, so in normal series motor. But when we want to recover, the mechanic must change the connections made,
<EMI ID = 13.1>
before the diagram in fig. 2.
We can delete this last maneuver to switch to recovery, while keeping the same arrangement
<EMI ID = 14.1>
<EMI ID = 15.1>
