Abstract
The invention relates to a maglev railway comprising a support and drive system of the long stator-linear motor type, magnetic support poles that are situated in the vehicle being additionally provided with linear generator windings (10) that generate electric energy in the vehicle. The aim of the invention is to prevent unwanted, periodic vibrations (ripples) from being generated at low speeds. To achieve this, according to the invention, the teeth (5) and grooves (6) of the long stator (3) are arranged in high-speed sections (2a) parallel to the cores and the linear generator windings (10) of the support magnets provided in said cores and in low-speed sections (2b) obliquely to said cores (7) and linear generator windings.
