This document discusses magnetic levitation (Maglev) technology and its applications, specifically focusing on Maglev trains. It provides 3 key points: 1) Maglev trains use magnetic levitation to suspend the train above the track without physical contact, reducing friction and improving efficiency. 2) Maglev trains offer benefits over traditional trains such as higher speeds, lower energy consumption, reduced emissions, and lower maintenance costs. 3) The document outlines the basic principles and components of Maglev train systems including levitation, guidance, and propulsion using electromagnetic forces and linear motors.

2. LEVITATION

3. Maglev Technology
Maglev=Magnetic + Levitation

4. Magnetic Levitation
•is a method by which an object
is suspended with no support
other than magnetic fields.

8. Magnetic force is used to
counteract the effects of the
gravitational acceleration and any
other accelerations.

9. REPUSION

10. ATTRACTION

11. WHY?

12. Levitation = No contact =No friction = No power loss
= Increases efficiency
No contact = No friction = No wear
= Reduce maintenance costs

13. 3/5/2016
The magnetic levitation technology
can be used as highly advanced and
efficient technology in the various
industrial applications.

14. APPLICATIONS

15. •Clean energy

16. •Aerospace

17. •Toys

18. •Weapons

19. •Transportation

20. MagLev Train
• uses noncontact magnetic levitation,
guidance and propulsion systems and
have no wheels, axles and
transmission.

21. - Driving Without Wheels - Flying Without Wings
- It doesn’t roll - It hovers .

22. Electricity and Electronics - Instead of
Mechanics

23. WHY?!

24. •Rapid growth of populations and
the never ending demand to
increase the speed of travel has
always been a dilemma for city
planners.

25. • Current land transportation is slow
• Land speed is limited by friction
• Flying is expensive
• Air and land travel takes up a lot of
fuel.

26. MAGLEV TRAIN VS
OTHERS

27. SPECIFIC ENERGY CONSUMPTION (watt-
hours / seat – kilometer)

28. OVERALL SYSTEM MAINTENANCE COSTS
(cent / seat –km)

29. CO2 Emission
(grams per seat – km)

30. • It is the first fundamental
innovation in railroad technology
since the construction of the first
railroad.

33. Types of Maglev Techniques
1. Electro magnetic Suspension - Attractive
2.Electro dynamic Suspension - Repulsive

34. Basic Principle of Maglev Trains
1.Levitation 2.Propulsion
3.Guidance

35. EMS SYSTEM (energy management system)

36. LEVITATION
•attractive forces created
between the train and the
track.

39. GUIDANCE
• functions according to the principle of
electromagnetic levitation.
• guidance magnets keep it laterally on
track.

41. PROPULSION
The synchronous longstator linear
motor of the maglev system is used
both for propulsion and
braking.
