  "description_excerpt": "The following relates to a module for a modular motorized drive system, in particular for doors, the module being designed for a number of modules arranged linearly one behind the other along a longitudinal axis of modules forming a functional group of the drive system. The following further relates to a modular, motorized drive system, in particular for doors, a number of modules arranged linearly one behind the other along a longitudinal axis of the modules, forming a functional group of the drive system. The following further relates to the use of a drive system according to the invention for operating a door, in particular a vehicle door. The following also relates to a production method for a modular, motorized drive system, in particular for doors.\n\nDrive systems for, in particular electromechanical, control of, for example, doors, in particular vehicle doors and vehicle flaps, are known from the conventional art. A force of an electric motor is transmitted to the vehicle door, for example via a threaded spindle. Furthermore, the drive systems can comprise, for example, a clutch to protect the vehicle door, in particular a connection element of the drive system to the vehicle door, against overloading or to reduce vibrations, a brake for holding the vehicle door in a certain position, a transmission for adjusting the transmitted force and speed and/or a bearing for absorbing forces exerted by the vehicle door on the drive system.\n\nA generic drive system is described for example in the document DE102014212863A1, the teaching of which, is included here by reference.",
