Due to this difference, however, the known method relies heavily on a real-time-capable data transmission channel from the vehicle to a stationary, or track-side, drive control device, so that attenuation of the pivoting movement of the vehicle is expensive. big

Embodiment Construction

[0035] exist figure 1 The front area of ​​the maglev vehicle 10 on the maglev railway section 20 can be seen in . exist figure 1 The section-side stator 30 , which is configured with stator slots 40 and stator teeth 50 , can be seen from the maglev railway section.

[0036] exist figure 1 The exciter coils for generating the stator magnetic field, not further shown in FIG. 2 , are located in the stator slots 40 . The fundamental wave of the stator magnetic field is at figure 1 Indicated with reference sign S. The magnetic reference axis Bs of the stator 30 is defined by the arrangement or position of the field coils.

[0037] exist figure 1 Only a section of the stator 30 is shown in the figure; the stator 30 extends through the entire section of the maglev railway and thus (as in figure 1 As can be seen in ) the stator magnetic field S is also generated before the magnetically levitated vehicle 10 .

Abstract

The invention relates to a method for the traction control of a maglev car (10) on a maglev track. According to said method, a levitation magnetic field (T) is produced on the maglev car by supplying a levitation magnetic flux on the car side to the at least two levitation magnets (60b, 60c) of the maglev car to produce a defined air gap (SP) between the maglev car and a reaction rail (20) on the track side. A stator current is supplied to the stator (30) on the track side of the maglev track to produce a propulsion force (Fx) on the maglev track, the propulsion force acting upon the maglev car being determined by the magnetic coupling between the magnetic stator field and the magnetic levitation field. According to the invention, a pendular movement of the maglev car in relation to the magnetic stator field is dampened by changing the magnetic coupling between the magnetic stator field and the magnetic levitation field on the car side. For this purpose, the levitation magnets (60b, 60c) are operated on the car side with at least two different individual levitation magnetic fluxes (Imag1, Imag2).

Description

technical field [0001] The invention relates to a method for driving and controlling a magnetically levitated vehicle on a magnetically levitated railway section, in which method: at least two support magnets (60b, 60c) of the magnetically levitated vehicle are fed with current from one vehicle-side support magnet respectively In, produce bearing magnetic field (T) on maglev vehicle, to set up the air gap (SP) between maglev vehicle and the reaction rail (20) of road section side; Stator (30) to generate the thrust (Fx) acting on the maglev railway section; wherein, the thrust acting on the maglev vehicle is determined by the magnetic coupling between the stator magnetic field and the supporting magnetic field. Background technique [0002] Such a method is used, for example, in Transrapid. [0003] At higher speeds, the pole voltage induced in the track-side stator by the bearing magnetic field of the moving maglev vehicle is observed in Transrapid. For this purpose, curr...
