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 &#65533; de l'excitatrice E (voir fig.2).

   <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 &#65533; 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.

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>
