This document discusses the design and analysis of a magnetic suspension system prototype. It provides background on early magnetic suspension systems from 1966. The major components of electromagnetic suspension systems are described as linear motors, electromagnets, thrust bearings and frames. There are three primary types of maglev technologies: superconducting magnets, feedback controlled electromagnets, and newer permanent magnet systems. The research aim is to design, analyze and compare a magnetic suspension system prototype to other suspension systems. Various analyses are presented on simulation of the system without and with a damper to stabilize the system. Results and comments on the modeling and a conclusion are also provided.

2. 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.

14. 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.

15. 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 .
