The magnetic levitation train, a flying train, Maglev.

Technology is in the process of development!

 

 

The magnetic levitation train the flying train, magnetophon or Maglev is a train, held over the road, driven and controlled by electromagnetic force or magnetic field.

Description:

The magnetic levitation train the flying train, or Maglev magnetophon (from the English. magnetic levitation – “magnetic levitation“) is the train held over the road, driven and controlled by the power of elektromagnitnogo magnetic field.

In contrast to the traditional railway trains in motion Maglev train does not touch the surface of the rail. Therefore, the speed of this transport can be comparable to the speed of the aircraft. Today the maximum speed of this train is 581 km/h (Japan).

In practice there are two systems of magnetic levitation: electromagnetic suspension (EMS) and electrodynamic suspension (EDS). Other systems: permanent magnets there are in theory only, and the system RusMaglev is in the process of development.

 


Train with electromagnetic suspension (EMS) :

Electromagnetic suspension (EMS) allows the train to levitate using electromagnetic field variable in time by force. The system is a path made of a conductor and a system of electromagnets mounted on the train.

The advantages of this system:

– magnetic field inside and outside the vehicle are less than EDS system,

economically feasible and available technology

– high speed (500 km/h),

no need for additional suspension systems.

The disadvantages of this system:

instability: requires permanent control and adjustment of fluctuations of the magnetic field paths,and composition

process alignment tolerances external means can lead to unwanted vibrations.

 

Train the electrodynamic suspension (EDS):

The system is the electrodynamic suspension (EDS) levitation creates a changing magnetic field in ways and the field generated by the magnets on Board the train.

The advantages of this system:

– development of very large velocities (603 km/h), and the ability to withstand heavy loads.

The disadvantages of this system:

the inability to levitate at low speeds, the need for high speed, that was quite repulsive force, at least for holding the weight of the train (therefore, these trains use wheels),

strong magnetic radiation is harmful and unsafe for passengers with weak health and with a pacemaker to magnetic storage media.

 

System magnetic levitation trains on permanent magnets Inductrack:

At the present time the actual embodiment is the system of permanent magnets Inductrack, which is the kind of system EDS.

The advantages of this system:

– potentially the most economical system,

low power to activate the magnets

– magnetic field is localized below the car,

field levitation is generated already at a speed of 5 km/h,

– if a power failure occurs, the cars stop safely,

a variety of permanent magnets may prove more effective than electromagnets.

The disadvantages of this system:

requires wheel or a special segment of the path supporting the train when it stops.

 

System RusMaglev:

Levitation RusMaglev is a Russian development. Levitation is created by permanent magnets (neodymium-iron-boron) on Board the train. The path is made of aluminum. The system requires absolutely no supply of electricity.

The advantages of this system:

– economical high-speed railway,

does not require electricity

– high speed – over 400 km/h,

the train is levitated at zero speed,

– transportation of goods in 2 times be cheaper than freight on the existing rail.
