Abstract

A drive device includes a rotational drive device with a rotating stator and a rotating armature for displacing a shaft in a rotational movement and a linear drive device with a linear stator and a linear armature for displacing a shaft in a linear movement. The rotational drive device and the linear drive device are arranged axially one behind the other, with the rotating armature and the linear armature being connected to a respective shaft section. The shaft sections of the rotating armature and the linear armature are axially aligned and connected to each other in a rotationally fixed manner such that the shaft sections can move axially with respect to each other but they can only rotate together.
