Claim Text:
1. A drive device, comprising: a shaft; a rotational drive device having a rotating stator and a rotating armature for imparting a rotational movement to the shaft, said rotating armature being connected to a first shaft section; a linear drive device having a linear stator and a linear armature for imparting a linear movement to the shaft, the rotational drive device and the linear drive device being arranged coaxially one behind the other, said linear armature being connected to a second shaft section in axial alignment with the first shaft section, with the first and second shaft sections being connected to each other so as to be movable axially with respect to each other but rotatable only together; and a detector, operably connected to a control and regulation facility, for ascertaining a highly dynamic movement of the shaft, said detector being at least one member selected from the group consisting of a sensor for detecting the linear movement of the shaft, and a hollow shaft sensor for detecting the rotational movement of the shaft, wherein said first shaft section and said second shaft section having axially proximal end portions which are arranged telescopically in one another and axially distal end portions which are axially spaced from each other and connected to the rotating armature and to the linear armature respectively, wherein said axially proximal end portions of said first shaft section and said second shaft section are arranged telescopically in one another with interposition of a torque linear bearing and radially inside said rotating armature of said rotational drive device.
