Abstract
A guideway for a magnetically levitated railway is described, having a longitudinal stator linear drive comprising at least two parallel stators. The guideway includes a plurality of supports ( ) arranged along a given line and adapted to form straight and curved guideway sections and stator sections mounted on the supports ( ), these sections being composed of straight stator end packs ( ) and likewise straight middle stator packs ( ) arranged therebetween, the packs in the region of the curved guideway sections being laid in the manner of polygonal trains to form outer and inner stator sections ( ) and being separated from one another by gaps ( ). The stator end packs ( ) and the middle stator packs ( ) have a predetermined tooth/groove pitch ( ) with reference to a conceptual space curve ( ) and different “ideal” lengths which differ from one another by fractions of a tooth/groove pitch ( ). The middle stator packs ( ) are so combined with one another in at least one outer or inner stator section ( ), taking into account their different “ideal” lengths, that a “material” total gap between the stator end packs ( ) and the middle stator packs ( ) of this stator section ( ) has the smallest possible width. A parts set and a method of making a double track guideway are also described (FIG. ).
