Magnetic levitation train

Belongs to:
Rail vehicle
Synonyms:
Maglev train, maglev
Description:

Magnetic levitation trains are rail vehicles for passenger transportation that are levitated a short distance away from the guideway using magnets in both train and railway to create lift and thrust. Velocity can be adjusted by changing the three-phase current frequency.

Frequency ranges:
  • 0 Hz
  • 16–512 Hz
  • 47.5–62.5 Hz
Type of field:
magnetic
