Abstract

Die Fördervorrichtung weist einen stromgesteuerten Motor, ein diesem nachgeschaltetes Getriebe zum Umsetzen der rotatorischen Rotorbewegung in eine translatorische Hubbewegung auf sowie eine davon angetriebene oszillierende Arbeitsmaschine. Der Motor wird von einer elektronischen Steuerung angesteuert, wobei der dem Motor zugeführte Strom (6 oder 7) entsprechend derzu erwartenden Motorbelastung in Abhängigkeit der Hubstellung der Arbeitsmaschine begrenzt wird. Hierdurch wird einerseits der Wirkungsgrad der Maschine erhöht und zudem eine unnötige thermische Belastung des Motors vermieden (Figur 3).
