  • Patent number: 10343534
    Abstract: An arrangement for inductively transmitting energy for charging an energy storage device of a rail vehicle. A first induction element transfers energy to a second induction element. An inverter with an adjustable AC voltage frequency provides an AC voltage to the first induction element. A controller controls the AC voltage frequency of the inverter. A measuring device ascertains a power output value during the wireless energy transmission and transmits the value to the controller and the controller adjusts AC voltage frequency of the inverter downward from an upper threshold until a pre-specified power output value is set while energy is being transmitted. The first induction element is paired with a track for rail traffic. The system and a method are also described for inductively transmitting energy for charging an energy storage device of a rail vehicle.

  • Patent number: 7362014
    Abstract: The invention relates to a method and an arrangement for operating a magnetically levitated vehicle by means of an arrangement having at least one long-stator linear motor. The linear motors are sub-divided longitudinally of a track into individual motor regions (A3, A4) in which only one vehicle (7e, 7f) at a time can normally travel. To increase the vehicle concentration along the track, provision is made in accordance with the invention for selected motor regions (A4) to be divided into at least two mutually independent motor region sections (A4a, A4b) and for one vehicle (7f, 7g) to be operated in each motor region section (A4a, A4b) at a part of that power which is preset for each motor region (A4).

  • Patent number: 6753666
    Abstract: An apparatus for operating a magnet vehicle, especially a magnetically levitated vehicle. The apparatus includes a long stator linear motor with at least one long stator winding laid along a track and at least one exciter arrangement cooperating with this winding and mounted on the vehicle. The long stator winding is divided into winding sections (5.4, 26.4) following one another, which each have a greater length than the exciter arrangement. At least two section cables serve to supply the winding sections with electric power and switch devices serve to connect the winding sections (5.4, 26.4) sequentially to a section cable each in correspondence with the progression of the vehicle. In accordance with the invention the winding sections (5.4, 26.

  • Patent number: 6087790
    Abstract: The present invention relates to a method for switching over the current between successive stators of a railway system comprising a track and a vehicle and with a long-stator linear motor. The method according to the present invention proceeds from a conventional double-infeed step-change method. During the switching over of the current from one stator section of a long-stator winding phase to the following one, the section cable, which is assigned to the stator sections to be changed over and is supplied with power from two substations by double infeed, is split up. In this way, the sections to be changed over can be supplied by single infeed by a single substation in each case. It is possible thereby to avoid the unilateral loss of thrust which occurs in the case of conventional step-change methods.

  • Patent number: 5569987
    Abstract: A power supply system for a long-stator drive, whose stator winding along a path for a magnetic levitation train is subdivided into several controllable stator segments. The stator segments are controllable via at least one segment switch on at least one section cable system running along the stator segments. At least one frequency transformer is provided per section cable system, with the frequency transformer(s) arranged in at least one substation along the stator segments. Each frequency transformer generates a supply voltage system for the stator segments, with the nominal voltage in the section cable system being greater than the nominal voltage of the stator segments. At least one matching transformer is connected between the section cable systems and the stator segments, through which the nominal voltage of the section cable system can be transformed down to the nominal voltage of the stator segments.

  • Patent number: 5302884
    Abstract: In a power supply system for a linear stator motor, the installed operating means should be utilized in an optimum manner, while the losses due to energy transfer should be maintained as low as possible. For this purpose, the cable route systems should be connected with each other by at least one controllable coupling switch, in such a way that the switching segment in which the vehicle is located at any particular time is always connected with all the cable route systems.
