Method and device for controlling the drive of a magnetic levitation vehicle on a magnetic levitation track

摘要

A method provides for the traction control of a maglev car on a maglev track. A levitation magnetic field is produced by supplying a levitation magnetic flux on the car side to at least two levitation magnets to produce a defined air gap between the maglev car and a reaction rail on the track side. A stator current is supplied to the stator to produce a propulsion force on the maglev track, the propulsion force acts upon the maglev car being determined by the magnetic coupling between the magnetic stator field and the magnetic levitation field. An oscillating 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. The levitation magnets are operated on the car side with at least two different individual levitation magnetic fluxes.
