 zeigen ; diese Kurve beginnt im Koordinatenursprung, biegt dann bald um (je nach Bemessung des Variationswiderstandes) und nimmt dann einen fast vertikalen Verlauf an. 



   Um nun die Charakteristiken des kombinierten, der Feldwicklung vorgeschalteten Widerstandes, d. h. die Abhängigkeit zwischen C2 und   (   + iv) =   i zu finden,   muss man jede aus der Schar der M-Geraden der Fig. 5 mit der L-Kurve in bezug auf die Abszissen addieren. Man erhält auf diese Weise eine Schar der M-Kurven (siehe Fig. 6) als Charakteristiken für den kombinierten,

   (siehe Fig. 1) in bezug auf die Ordinaten addieren, und so kommt man zu den Kurven v8, t... Vx (Fig. 7), deren jede einem bestimmten Werte des Regelungswiderstandes entspricht. und die   Kurve   K   in je einem bestimmten Punkt scharf schneidet. 



   Es ist klar, dass, wenn man die obenbeschriebenen Schaltanordnungen. anstatt in Verbindung mit nur einem Teil oder einigen Teilen der Feldwicklung verwendet, das gleiche Resultat erhalten wird : die Charakteristik des betreffenden Teiles des   Erregerstromkreises     wird ungeradlinig.   folglich weicht auch die Charakteriskik des Gesamterregerkreises von dem geradlinigen Verlauf ab. Sie fällt also wiederum nicht mit dem geradlinigen Teil der Magnetisierungskurve zusammen. sondern schneidet diese scharf in einem Punkte wodurch wieder das stabile Arbeiten der Maschine erreicht wird.

 demonstrate ; this curve begins at the origin of the coordinates, then soon bends (depending on the dimensioning of the variation resistance) and then assumes an almost vertical course.



   In order to now examine the characteristics of the combined resistor connected upstream of the field winding, i. H. To find the relationship between C2 and (+ iv) = i, each of the family of M-straight lines in FIG. 5 must be added to the L-curve with respect to the abscissas. In this way a family of M curves (see Fig. 6) is obtained as characteristics for the combined,

   (see Fig. 1) with respect to the ordinates, and this leads to curves v8, t ... Vx (Fig. 7), each of which corresponds to a specific value of the control resistor. and the curve K intersects sharply at a specific point.



   It is clear that if one uses the switching arrangements described above. instead of being used in conjunction with only a part or some parts of the field winding, the same result is obtained: the characteristic of that part of the excitation circuit becomes irregular. consequently, the characteristics of the overall excitation circuit also deviate from the straight line. So again it does not coincide with the rectilinear part of the magnetization curve. but cuts it sharply in one point, which means that the machine can work again reliably.
