Maglev

• Rapid and mass transit in the future

4
Advantage of Maglev

• High speed
• Silent
• Low energy

5
About High speed running

• Wheeled
• There is problem low friction
• Rolling friction lt air resistance
• Max speed
• TGV (France) 320km/h
• Magnetic
• Only air resistance prevents from running
• Max speed
• Shanghai Maglev train (China) 430km/h
• JR-maglev (Japan) 581km/h ? 700km/h !?

13
What device does produce the electromagnetic
power?

• Train hassuperconducting magnetic coils

• Guide way has levitation, guide, driving coils

14
SCM(Superconducting magnetic coil)
15
Coils located on the guide way

• Driving coil

• Levitation and guide coil

16
Construction of guide way
17
Why is the electromagnetic force produced ?

• Lenzs law
• If magnetic filed change, current flows against
  it

18
SCM runs over shorted coils
19
Application of levitation

• Set coils, which shape is 8, to wall surface of
  guide way
• Flux level
• Downside coil gt Upper coil

Application of guide

• Connect side coils
• (Blue line)
• Flux level
• Right side coil gt Left side coil

Concluding remarks

• On March 11, 2005, the MPTEC acknowledged
  thatThrough running tests and technological
  advances, technologies of the JR-Maglev have been
  greatly progressed.The technologies necessary
  for the future revenue service were extensively
  established
