Abstract

A linear drive device has a stator and an armature able to be moved in relation to the stator in a linear manner. The device furthermore comprises an electrodynamic linear direct drive system and a fluid power drive system. Using the two drive systems it is possible in an independent manner for setting forces to be applied electrodynamically and by fluid power to the armature.
