Abstract: Linear motor comprising a stator, and a mobile motor part comprising at least one motor element separated from the stator by an airgap (G) configured to be electromagnetically coupled thereto to generate thrust on the mobile element in a track direction (A). At least one of the stator and the mobile motor part comprises an electromagnet and at least the other of the stator and mobile motor part comprises one or more of a permanent magnet, an electromagnet, an induction plate. The linear motor further comprises at least one control system, airgap sensors connected to the control system configured to measure a length of the airgap between the mobile motor part and the stator, and actuators connected to the control system coupled to a support of the mobile motor part and to the motor element, the actuators receiving control signals from the control system to adjust said length of the airgap.

Abstract: Vacuum tube railway system comprising a vacuum tube mounted on a ground support, a magnetic levitation railway track mounted inside a wall forming the vacuum tube for guiding a magnetic levitation railway vehicle, the vacuum tube assembled in sections along the ground support, at least some of a plurality of sections of vacuum tube being coupled together by a dilatation joint configured for hermetically sealing a dilatation gap between said sections of tube. The dilatation joint comprises at least first and second support plates mounted on an outer surface of the tube wall, a first support plate fixed to a first section of vacuum tube and a second support plate being fixed to a second section of vacuum tube, the support plates extending longitudinally over the dilatation gap over a length (L1) greater than a maximum dilatation gap (G).

Abstract: The subject matter of the invention is the method of construction of a linear motor winding, consisting of phase paths, characterised in that a solid flat bar is cyclically bent at a selected binding radius R1, the active part and the end parts constitute a uniform plane of the phase path, which has got elongated end fragments: the beginning of the section and the end of the section or the phase path is cut of metal sheet, as shown in the figure and then, along the line, separating the end part from the active part, it is bent at the bending radius R2, where the bend angle ?1 is within the range between 0° and 180°.
