BACKGROUND

• In 1966 Danby and Powell proposed an EDS system
  for high-speed transportation using super
  conducting magnets with a null flux suspension.
• Subsequent researchers in the U.S., Japan,
  Germany, UK and Canada have developed further
  innovations (such as ladder type guide way for
  increased lift efficiency), but there are still a
  number of technical problems that needed
  resolution.

MAJOR COMPONENTS IN EMSS

• A Linear motor as a damper or A Hydraulic Damper
• Two Electromagnets
• Thrust bearings
• Frames

CURRENT DETAILS OF EMSS

• There are three primary types of Maglev
  technologies
• superconducting magnets ( electrodynamic
  suspension)
• feedback controlled electromagnets
  (electromagnetic suspension)
• Newer potentially more economical system using
  permanent magnets Inductrack.

COMMENTS

• As the current u increases the distance x
  decreases.
• As the current increases the magnetic force F
  increases causes the movement of the ball towards
  the coil.
• The damper absorbs the oscillations as shown in
  the Result 2.

CONCLUSION

• An approach of the magnetic suspension system has
  been presented. The simplified mathematical model
  has been developed.
• The EMSS has the ability to give much smoother
  ride than any luxury sedan, and less roll and
  pitch than any sports car .
