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 EMSSThere 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.
RESEARCH AIM AND OBJECTIVESAim: To design and analyse a prototype Magnetic
Suspension System. Objectives:Literature ReviewResearch of the principles of the various types of
suspension systems and analysing their functions and performances.
Design a prototype Magnetic Suspension System.Analyse the designed Magnetic Suspension System.Compare with the other type of Suspension
Systems.Conclusion.

COMMENTSAs 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.
CONCLUSIONAn 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 .
