Abstract

A device comprising a base body is provided. A stator pack of an electric machine is connected to the base body by means of a connecting structure. The electric machine includes a rotor which cooperates electromagnetically with the stator pack and is rotatably mounted relative to the stator pack such that the rotor can rotate about the rotational axis. The stator pack is fixed by means of the connecting structure relative to the base body. The stator pack includes a plurality of stator sheets which are stacked on top of each other when seen in the direction of the rotational axis. Electromagnetically inactive first intermediate layers are arranged at least between certain stator sheets. The first intermediate layers are components of the connecting structure. Torque exerted upon the rotor by means of the stator pack is transferred in the connecting structure by means of the layers.
