Abstract

Offenbart wird eine Rotorblattverstelleinrichtung einer Windkraftanlage mit einer drehzahl- sowie richtungsvariablen Motor-Pumpeneinheit, die über eine hydraulische Steuerung/Regelung mit einem hydraulischen Aktor fluidverbunden ist. Der Aktor ist mit zumindest einem Rotorblatt der Windkraftanlage für dessen Verdrehung um seine Längsachse mechanisch gekoppelt. Zum Betreiben des Motors ist erfindungsgemäß ein eine Not-Energieversorgungseinrichtung umfassender elektrischer Steuerkreis vorgesehen.
