Abstract: A method for attaching a plurality of fasteners located along a circular path uses a screwdriving device that has feed drive outputs. The drive outputs correspond to the fasteners, are located on a circular path and include a screwdriving tool bit. During the method, the drive outputs are extended from a position of repose to a working position and the screwdriving tool bit, located at the fastener, screws in the fastener. The feed drive outputs are located on circular paths of different diameters and only those drive outputs located on a particular circular path, which corresponds with a circular path on which the fasteners are located, leave their position of repose. The number of feed drive outputs corresponds to the number of fasteners.

Abstract: The invention relates to a double-fed asynchronous generator, which is provided with a slipring rotor (1b), and to a method for its operation. In the normal manner, the asynchronous generator has a machine-side converter (5) and a network-side converter (6). According to the invention, the asynchronous generator is designed to supply short-circuit power in that at least one machine-side rotor current (iRM) is maintained in the event of a short circuit, in order to allow the formation of a stator-side short-circuit current. In order that inherent short-circuit currents in sensitive components of the converters (5, 6) are nevertheless avoided, at least the machine-side rotor current (iRM) is maintained in such a way that the actual rotor current (iRMact) in the event of a short circuit is used as the new nominal value in a control apparatus for the asynchronous generator.
