   Wird der Ständer von Hochspannung gespeist, dann kann gefordert werden, dass die Hochspannung von dem Läufer ferngehalten werden soll. Da aber bei den Schaltungen nach Fig. 6 und 11 der Läufer in leitender Verbindung mit der   Ständerwicklung   steht, so ist eine Sicherung gegen Hochspannung in diesem Falle am besten durch Erdung zu erreichen. Für den Anschluss einer 
 EMI4.1 
 Bürstensätze   b1   und b2 geschaltet ist. Von dem Nullpunkt der Drosselspule wird die Erdungsleitung abgezweigt. 



   Das   Übersetzungsverhältnis   des Transformators T kann natürlich auch regelbar gemacht 
 EMI4.2 
 andere Regelungskreise überzugehen. Gleichzeitig kann auch den neuen Bedingungen entsprechend der feste Winkel y je eine andere Einstellung erfahren. 



   PATENT-ANSPRÜCHE :
1. Einrichtung zum Regeln von   Mehrphasen-Reibenschlussmotoren   mit Doppelbürsten durch   B rstenverschiebung   eines Bürstensatzes, dadurch gekennzeichnet, dass die Stromverteilung auf die beiden Bürstensätze ungleich gemacht, dass ferner der den grösseren Strom führende Bürstensatz als feststehender Bürstensatz zweckmässig in gegen die Ständerwicklungsachse verstellter Lage verwendet wird und dass hiebei das   Windungsverhältnis   der Ständer zur Läuferwicklung oder das Stromverhältnis der   Ständer-zur Läuferwicklung   oder das Stromverhältnis des Ständer- zum Läuferstrom derart gewählt wird, dass die durch den Strom des festen Bürstensatzes erzeugte Läuferamperewindungszahl kleiner als die Ständeramperwindungszahl ist.

   If the stator is fed by high voltage, then it can be required that the high voltage should be kept away from the rotor. However, since the rotor is in conductive connection with the stator winding in the circuits according to FIGS. 6 and 11, protection against high voltage can best be achieved in this case by grounding. For connecting a
 EMI4.1
 Brush sets b1 and b2 is switched. The grounding line is branched from the zero point of the choke coil.



   The transformation ratio of the transformer T can of course also be made adjustable
 EMI4.2
 to pass other regulatory circles. At the same time, the fixed angle y can also experience a different setting depending on the new conditions.



   PATENT CLAIMS:
1. Device for regulating multi-phase friction motors with double brushes by brush displacement of a brush set, characterized in that the current distribution to the two brush sets is made unequal, and that the brush set carrying the larger current is also used as a fixed brush set in a position displaced from the stator winding axis and that the turns ratio of the stator to the rotor winding or the current ratio of the stator to the rotor winding or the current ratio of the stator to the rotor current is selected such that the rotor ampere-turns generated by the current of the fixed brush set is less than the stator ampere-turns.
