Method and device for measuring the pole position angle of a magnetic levitation vehicle of a magnetic levitation system
Abstract:
A method for measuring the pole position angle between the magnetic field of a track-side stator of a magnetic levitation train track and the magnetic reference axis of a magnetic levitation vehicle located on the track. When the levitation magnet of the magnetic levitation vehicle is energized, a direction component of the magnetic field of the stator, which component is predefined by a preferred measurement direction of the magnetic field sensors, is measured using a pair of magnetic field sensors, and the pole position angle is determined using the measured values of the two magnetic field sensors. The preferred measurement direction is set in such a way that at least one of the two magnetic field sensors has a minimum measurement sensitivity for the magnetic field of the levitation magnet.
