摘要

For a machine or a machine section for the production or / and finishing or / and other treatment or / and handling of a running web of material, in particular of paper or cardboard, comprising at least one rotary component (108) which, by means of at least one electric motor (12) can be driven, the one hand, with the rotary component in the sense of a rotary drive or, which is coupled to the rotor and a can be coupled directly or indirectly to a frame of the machine and / or of the machine section or a relative to the frame which is positioned movably supported against rotation motor stator is provided, according to one aspect of the invention, it is proposed that the electric motor as a synchronous motor (12) or can be operated in such a way that the electric motor and coaxially with respect to the rotary component (108) in association with one axial end region (24) thereof is arranged or can be arranged, wherein the rotor or a rotary drive connection (18) of the same for the essentially play-free common rotation in a rotationally fixed manner directly with the rotary component or a rotary drive connection (24) of the same is coupled or. In the case of the rotary component can be, for example, a drying cylinders in a drying section or the winding core (108) of a wound roll in a machine or a machine section for the winding up of the material web on the winding core to the winding roller or / and for unwinding the web of material may be from the winding roller.
