Einrichtung zum Uniformen der Frequenz und Spannung von Wechselstrom unter Benutzung eines Frequenztranaiormators, bestehend aus einer fortlaufenden, mit entsprechenden Punkten an das Netz angeschlossenen Wicklung, der mit Hilfe eines Kollektors und relativ gegen die Wicklung umlaufender Bürsten, Strom veränderlicher Frequenz entnommen wird, und einem Spannungstransformator, um jeder Frequenz die geeignete Spannung zu geben, gekennzeichnet durch Anordnung des Spannungstransformators zwischen dem Frequenztransformator und dem Verbrauchakörper zum Zwecke, Verringerung der Bürstenströme und dadurch Verbesserung der Kommutierung zu erzielen.
EMI2.2
Device for the uniformity of the frequency and voltage of alternating current using a frequency transformer, consisting of a continuous winding connected to the network at appropriate points, which is drawn with the help of a collector and brushes rotating relative to the winding, current of variable frequency, and a voltage transformer , in order to give each frequency the appropriate voltage, characterized by the arrangement of the voltage transformer between the frequency transformer and the consumer body for the purpose of reducing the brush currents and thereby improving the commutation.
