Die jeweilige Antriebsvorrichtung der Seilbetätigungseinrichtungen kann ein permanentmagneterregter Synchronmotor sein, der sein Drehmoment über ein Getriebe auf die Seil-Trommel überträgt. Das Getriebe ist zweckmäßigerweise als ein Planetengetriebe ausgebildet.The respective drive device of the cable actuation devices can be a permanent magnet synchronous motor his, the torque via a gear on the rope drum transfers. The gear is conveniently as a planetary gear.

Jede Antriebsvorrichtung kann mit einem eigenständigen, integrierten Frequenzregler ausgestattet sein. Besonders vorteilhaft ist allerdings eine Ausführung, bei der mehrere Antriebsvorrichtungen mit einem gleichen Frequenzregler betrieben werden und hierfür beispielsweise eine Schaltung über ein Bus-System vorgesehen ist.Each drive device can have its own, integrated Frequency controller.
