Zusammenfassung:In order to reduce the additional losses and short-circuit forces in the case of strip windings, it is provided for at least one of the two strip-connecting rails to be supplied from both ends. When the two strip-connecting rails are supplied from both ends, the supply leads are passed outside the windings. In the case of three-phase windings which are connected in star, in each case one star-point rail is provided in the vicinity of the upper end and lower end of the corresponding strip-connecting rail in order to minimise the supply lead lengths, which star-point rails can be connected to one another. If one strip-connecting rail is supplied at one end and the other at both ends, then the current in the rail which is supplied at two ends is used to form an opposing flow for the rail which is supplied at one end.
