ABSTRACT:
A method for measuring the pole position of a magnetic levitation vehicle in a magnetic levitation railway, wherein a supporting magnetic field is generated on the maglev vehicle as a result of a supporting magnetic current on the vehicle side being fed to at least one supporting magnet. The voltage in the stator on the track is measured and the pole position angle between a reference axis of the stator and a reference axis of the maglev vehicle is determined. The magnitude of the supporting magnetic current on the vehicle side and thus the supporting magnetic field is temporally modified and a voltage induced in the stator by the temporal modification of the magnitude of the supporting magnetic field is detected. The pole position angle is formed using the measured values for the induced voltage.
