What maglev train:
The MagLev use magnetic trains
suspended in the tracks above. Maglev
trains are often referred to as the
MagLev, Magnetically Levitated train
shorthand.
Inventor:
In 1922, the German Hermann Kemper
electromagnetic floating principle, in
1934 the world‘s first one on the maglev
technology patent.
Two types of maglev in the world:
 Japan represented superconductivity maglev.
 Germany,represented by the often conductive
magnetic levitation.
Japan ML100
German Transrapid 07

Maglev technology is divided into tracks,
vehicles, traction, run control four systems,
16 core technology.


The maglev train propulsion system with
motor propulsion, equivalent to the portion
of the motor housing fixed on the ground,
and the rotary motor magnet mounted on the
vehicle body electromagnet instead.The
opposite wall with both side of the train,
equipped with the equivalent of general
motor field coil coil, pass on the current, it
will become an electromagnet.

Disadvantage
EMS
Train inside and outside of the
magnetic field is low compared to
the electric power suspension.
Has proved technically up to a
very high speed (over 500 km / h).
Due to the inherent instability of
the system need to be constantly
revised and external systems,
vibration may cause a problem in
EDS
Built magnet is substantially used
in the train and the track,
technically up to a very high
speed (581 km / h) and a high
load capacity.
The inducibility of the tracks will
limit the maximum speed of the
train, the train must have a
rotation running at low speed.
