PATENT-ANSPRUCH :
Verfahren zur Nutzbremsung von Wechselstrom-Reihenschlussmaschinen, die während der Generator- Periode vom Netz aus fremderregt werden, dadurch gekennzeichnet, dass die Spannung der Erregerwicklung durch Nebenschalten von Ohmschen Widerstand und Hinterschalten von induktivem Widerstand gegen die Netzspannung in der Phase verschoben wird.
EMI2.1
PATENT CLAIM:
Method for regenerative braking of alternating current series-wound machines that are externally excited from the mains during the generator period, characterized in that the voltage of the excitation winding is shifted in phase against the mains voltage by connecting ohmic resistance and inductive resistance in series.
