Maglev trains use magnetic levitation to float and propel trains through guideways at high speeds without friction. They levitate using magnets that repel each other between the track and train. This allows maglev trains to reach speeds over 300 mph. Current maglev projects exist in Germany, Japan, and the United States, but costs remain high. While maintenance is cheaper than wheeled trains and noise and pollution are reduced, concerns remain regarding electromagnetic interference and high infrastructure expenses.
The document discusses different types of maglev transportation technologies, including electromagnetic suspension (EMS) and electrodynamic suspension (EDS). It covers the basic mechanics of levitation, propulsion, and guidance for both types. Key advantages of maglev trains are discussed, such as very high speeds and low maintenance requirements compared to conventional trains. Existing and proposed maglev systems around the world are also summarized.
1. Magnetic levitation uses magnetic fields to levitate metallic objects and can be achieved through ferromagnetism or diamagnetism.
2. The most important application is trans-rapid magnetic levitation trains, which are propelled by electromagnetic or electrodynamic suspension.

It describes how maglev trains work by using powerful magnets and electromagnetic coils to repel the train above the track at speeds up to 310 mph. There are two main types of maglev trains - ones using electromagnetic suspension and ones using electrodynamic suspension. The document outlines the advantages of maglev trains in terms of their high speed and environmental friendliness, but also notes their large costs to build compared to conventional rail systems.
Magnetic levitation uses magnetic fields to suspend and propel objects such as trains without physical contact. There are two main types - electromagnetic suspension which uses magnets to attract a train to a track, and electrodynamic suspension which uses repelling magnetic fields. Maglev trains can reach speeds over 300 mph due to the lack of friction and can be more energy efficient and environmentally friendly than wheeled trains. However, the technology is very expensive to implement and provides less flexibility in routes compared to traditional trains. Several countries are working on maglev projects to develop this promising transportation system.
Maglev trains use magnetic levitation to float and propel trains along guideways without touching the surface. This is achieved through the interaction of magnets and electromagnetic coils that create both lift and thrust. Maglev trains can travel at speeds over 300 mph and have several advantages over conventional trains, including higher speeds, less energy use, and no friction between train and rails. While still under development, countries like Germany and Japan have operational maglev systems that could be improved upon to create faster, more efficient train travel in the future.
The document discusses the principles and systems behind magnetic levitation (Maglev) trains. Maglev trains use magnetic fields produced by electromagnets to levitate above tracks and propel the train without friction. There are two main suspension systems - electromagnetic suspension uses electromagnets on the train attracted to a T-shaped guide rail, while electrodynamic suspension uses superconducting magnets on the train to float above tracks powered by changing magnetic fields. Maglev trains offer advantages like less energy use, lower noise, lower operating costs, and virtually no risk of derailment compared to traditional trains.
The document discusses the principles and operation of maglev trains. It begins by providing a brief history of steam locomotives and their increasing speeds over time. Maglev trains levitate above tracks using magnetic fields and have no contact with the tracks. There are two main types - electromagnetic suspension (EMS) which uses attractive forces, and electrodynamic suspension (EDS) which uses repulsive forces between magnets on the train and guideway. Propulsion is provided by linear induction motors or synchronous motors that accelerate the train. Lateral guidance is achieved through the shape and positioning of levitation magnets and rails. Key advantages of maglev trains include very high speeds, low noise, minimal pollution and energy use.
This document discusses magnetic levitation trains (Maglev trains). It describes two main types of Maglev trains: electromagnetic suspension (EMS) and electrodynamic suspension (EDS). EMS uses electromagnets to attract the train to the track for levitation and propulsion, while EDS uses superconducting magnets and repulsion for levitation. The document outlines the basic principles, pros and cons of each system and concludes that Maglev trains offer a more efficient transportation alternative with advantages like very high speeds and less environmental impact.
This document summarizes a seminar presentation on maglev trains. It begins by defining maglev as magnetic levitation and uses the example of maglev trains. It then explains the basic principles of levitation, propulsion, and lateral guidance for maglev trains. The document discusses the two main types of maglev technologies - electromagnetic suspension (EMS) and electrodynamic suspension (EDS) - and compares their pros and cons. It also briefly introduces the Inductrack system and discusses potential applications and benefits of maglev trains in terms of comfort, economic efficiency, speed, safety, and maintenance.
Maglev system represent a promising evolution in high-speed ground transportation, offering speed in excess of 500 mph along with the potential for low operating costs and minimum environmental impact. The goal of this effort is to investigate the feasibility and viability of maglev systems in the Japan. The emergence of a sophisticated technology such as maglev requires a need for a co-ordinated research test program and the determination of test requirement to identify mitigate development risk and maximum use of domestic resources. The study is directed towards the identification and characterization of maglev system development risks tied to preliminary system architecture. Research objective are accomplished by surveying experiences from previous maglev development program both foreign and domestic, and interviews with individuals involved with maglev research and testing.
The document discusses bullet trains, which use magnetic levitation to suspend and propel trains along guideways using magnets rather than wheels. It describes the electromagnetic and electrodynamic suspension systems that levitate the train above the track and propel it forward. Bullet trains can reach speeds over 300 mph since there is no friction, require no fossil fuels, and are safer and more efficient than conventional trains. They are better for the environment due to lower energy use and emissions.
Maglev trains use magnetic levitation to float above the track and propel vehicles without friction. They can reach speeds over 500 km/h, faster than F1 cars or traditional trains. Maglev trains have been introduced in several countries since the 1960s for their high speed, low noise, and ability to operate in all weather conditions with minimal maintenance requirements compared to mechanically-powered trains. Shanghai, China claims the fastest maglev train at 501 km/h.

This document discusses maglev trains, which use magnetic levitation to glide along tracks without touching the surface. It describes how maglev trains are propelled and guided using electromagnetic forces that lift and propel the train. Maglev trains offer advantages like higher speeds, less noise and pollution, and lower maintenance compared to traditional trains. However, their infrastructure is more expensive to build initially. The document outlines the basic principles, components, advantages and applications of maglev train technology.
Maglev trains use electromagnets on the train and guideway to levitate the train using magnetic repulsion. Electromagnets in the guideway walls alternately pull and push the train using changes in magnetic polarity to propel it forward at speeds over 300 mph. While maglev trains have advantages like not burning fossil fuels and potentially less maintenance needs, their guideways are more costly to build than conventional train tracks.

Topic:
Nonfunctioning magnetic levitation (Maglev) train at Old Dominion University (ODU)
Thesis:
Superconducting magnets, created by cooling electromagnets to low temperatures, can reduce
power consumption and cost. A combination of superconducting magnets, and a fusion of
electromagnetic suspension (EMS) and electrodynamic suspension (EDS) technology can both
reduce cost and provide stability between magnetic forces.
Background:
The Mechanics of a Maglev Train
Magnetic levitation (Maglev) trains operate through the use of electromagnets, which are
magnets created by electric current. An electromagnet is defined as “a coil of insulated wire
wound around an iron or steel cylinder”, and functions “when current flows through the coil,
[producing] a magnetic field” (Gibilisco, 2001). These electromagnets are used to lift the train
above its track, as well as propel it forward. For propulsion, most Maglev trains use
electromagnets as an element in linear motors. A linear motor is essentially a regular motor,
whose components have been unraveled and shaped into a linear configuration so that it can then
be laid flat, such as for some modern magnetically-propelled rollercoasters, and Maglev trains. A
linear motor is officially defined as “a motor in which the stator and rotor are parallel and
straight” (Gibilisco, 2001). In a regular motor, “a central core of tightly wrapped magnetic
material (known as the rotor) spins at high speed between the fixed poles of a magnet (known as
the stator) when an electric current is applied” (Woodford, 1999). In a linear motor, the rotor
glides forward past the stator in a linear configuration instead of around in a rotational one.

Woodford, 1999).
Some Maglev trains use designs with a magnetized track, and others use designs with magnets
solely located on the train, but electromagnets and linear motors remain key elements for lift and
propulsion in either design.
Types of Maglev Trains
For example, Old Dominion’s train uses what resembles a rollercoaster track as part of its “smart
train - dumb track” design (Rau, 2006). This simply means that, unlike other Maglev trains
around the world that use a smart track - dumb train design, ODU’s track is made of non-
magnetized steel, while all of the magnets are instead located on the train. Having the more
intricate technology located on the train instead of the track greatly reduces cost, as it is
expensive to lay miles of track that are magnetized properly for Maglev train use. Many
commercial Maglev trains currently in operation use the smart track- dumb train design as it has
proven to create more stable magnetic forces than the alternative. However, this is only a
realistic and viable design for commercial Maglev trains, as the income from passengers and
governmental funding help pay for the expansive magnetized track.
There are two main types of Maglev trains, electromagnetic suspension trains (EMS) and
electrodynamic suspension trains (EDS). The most significant difference between the two is that
EMS trains only use one varying magnetic field to maintain stable levitation above the track,
whereas EDS trains use a magnetic field exerted by both the track and the train to create a strong
and unwavering balance of forces. Because EMS trains only have one magnetic field to keep
them properly levitated, and magnetic attraction varies significantly with distance, a small
change in distance between the train and the track can cause the train to crash. A crash would not
3. likely cause damage as Maglev trains do not levitate very far above their tracks, but proper
levitation would then need to be achieved again before the train could progress. EDS trains do
not experience this difficulty as, if the train becomes too close to the track, the magnetic field of
the track repels it back to its original position.
Figure 2. Comparison of EDS and EMS technology. (Image from Letts, 2012).
Although EMS trains are not as stable as EDS trains, they are less expensive, due to all of the
electromagnets being located on the train instead of the entirety of the track as mentioned, and
are able to reach higher speeds. Old Dominion’s train is an EMS train, much like the one
pictured in Figure 2. Metal arms connect the train to the track, and the magnets used for
propulsion and lift are located in the bottom of the arm, beneath the track.
Figure 3. Old Dominion University’s electromagnetic suspension train. Notice the metal arms
that house the magnets connecting the train and the track. (Image from Frank Batten College of
Engineering and Technology, 2006).
EDS trains are more stable, but when operating at slower speeds, occasionally do not have
enough magnetic force to support the weight of the train without the use of mechanical means.
4. Because the track’s magnetic field cannot always support the weight of the train, the train must
have wheels to support the train until it reaches a speed at which it can accomplish levitation.
The speed relative to the track is not a factor in levitation with EMS trains such as ODU’s train,
as EMS trains reach higher speeds much faster, and at any speed can effectively sustain
levitation if the right balance is found. EDS trains’ inability to levitate at slow speeds, and EMS
train’s instability both create issues of safety. Because a train may need to stop at any location on
the track due to technical failures or other urgent situations, the entire track must be able to
withstand a train travelling slowly or attempting to come to a stop by mechanical means.
Advantages of Maglev Trains:
For Old Dominion’s Maglev train in particular, the train could provide safe and fast transport
across the highly trafficked road, Hampton Boulevard, as well as through the rest of campus. The
train car is designed to hold approximately 100 passengers at a time, and, because there would be
multiple stops along the track, only reaches a top speed of about 45 miles per hour. This is still
an improvement over otherwise travelling on foot through campus (Frank Batten College of
Engineering and Technology, 2006).
Maglev trains have other advantages in general as well. Because no contact is made between the
train and the track, Maglev trains allow for near-frictionless travel. This near-frictionless travel
has numerous benefits including higher speeds, less noise, resistance to poor weather conditions,
and decreased maintenance. Maglev trains initially cost more than conventional means of
transportation during construction, but with conventional transport, friction between the wheels
and the track often causes damage over time, which requires both funds and labor to repair.
Maglev trains do not experience this physical stress, and thus, require only slight further funding
once they are built. Maglev trains are not entirely frictionless, however. They simply experience
no surface friction, which does help decrease maintenance and power consumption. Maglev
trains do, however, still experience air resistance and slight electromagnetic drag, but these
conditions are present in negligible amounts. The air resistance experienced does create sound,
but seeing as this is the singular source of sound, this makes Maglev trains quieter than
conventional transport as well. Minimal human interfacing is required beyond the construction of
the trains and programming of systems, as most systems used to control the train are computer
operated or otherwise automated. Furthermore, as most Maglev trains are elevated above the
5. ground, there is little danger of the train colliding with anything, such as other vehicles or
pedestrians, and the powerful electromagnets keep the train firmly on the track at all times.
Problem:
Old Dominion University’s Maglev train is currently not functional due to a variety of technical
shortcomings experienced during its construction and testing. Firstly, the amount of power
required to levitate the train off of the track is difficult to achieve and costly. During initial stages
of testing, the train was only able to maintain proper levitation above the track for a short
distance. It is often the case that problems arise with Maglev trains with the “cost [and] difficulty
of developing suitable electromagnets. Enormously powerful electromagnets are required to
levitate and move a train, [and] consume substantial amounts of power” (Woodford, 1999).
Secondly, power is also consumed when the train is attempting to “overcome air resistance, as
with any other high-speed form of transport” (Prasad, 2014). Lastly, it is also difficult to
maintain the proper distance from the track because Old Dominion’s train is an EMS train,
making it more unstable and harder to balance than EDS trains.
Solution:
Superconducting Magnets
To reduce the amount of power consumed and associated cost, the electromagnets used for lift
and propulsion of the train can be replaced with electromagnets cooled to low temperatures,
making them superconducting magnets. “[…] If electromagnets are cooled to low temperatures,
electrical resistance disappears almost entirely, which reduces power consumption considerably”
(Woodford, 1999).
A superconducting magnet is an electromagnet that is cooled to as close to absolute zero, or 0
Kelvin, as possible using “liquid helium or nitrogen” (Woodford, 1999). The electromagnet is
contained in an apparatus known as a cryostat, which is simply “a chamber for maintaining a
very low temperature for cryogenic operations” (Gibilisco, 2001). For structural integrity, safety,
and conservation of materials the cryostat is usually constructed with an outer shell that holds
liquid nitrogen, and the electromagnet itself is in an exterior structure composed of copper.
Copper is excellent for conductivity and therefore can also be used to provide a path of low
resistance. Optimally, the power supply for a superconducting magnet should be high current and
6. low voltage, as magnets are very inductive, and changes in current can cause spikes in voltages.
Spikes in voltage provoke safety concerns, both for the system and for potential passengers. Old
Dominion’s train has precautionary measures in place to alter current gradually including “a
computer with new programming [. ] and additional sensors” to control these processes (Frank
Batten College of Engineering and Technology, 2006).
Because electrical resistance is decreased with the use of superconducting magnets, the
installation of such an electromagnet could reduce Old Dominion’s Maglev expenditures.
Figure 4. A Superconducting Magnet. Notice areas designated for liquid helium and nitrogen, as
well as the outer casing –the cryostat. (Image from BRUKER Biospin, 2006).
Combining EMS and EDS technology (Bogie)
As mentioned, Old Dominion’s Maglev train is an EMS train, meaning that it is capable of
higher speeds, but is inherently less stable than an EDS train. If elements of EMS and EDS
technology are combined, this could create greater stability between the magnetic forces
levitating the train. Old Dominion has already released plans including a cart called a “bogie”,
which runs along the undercarriage of the train providing a counterbalance to the downward
magnetic force much like EDS technology, but works in tandem with the existing EMS
technology. In essence, instead of magnetizing the entire track, the bogie would achieve the same
amount of stability between magnetic fields, but using only enough resources to span the
undercarriage of the train. However, Old Dominion’s current design includes an array of
7. permanent magnets rather than superconducting magnets. “The permanent magnets on the
vehicle are organized into pods [and] the pods are combined into a bogie that will be used”
(Thornton, 2008). For the most part, the proposed bogie design would be effective in suspending
the train, propelling it forward, and “control[ling] the magnetic gap” that has presented itself as
an issue, but the addition of superconducting magnets would merge well with the design and
keep the cost of operating the train down (Thornton, 2008).
Figure 4. Head-on view of EMS/EDS Bogie designed to fit under the train and stabilize magnetic
forces. Grey post at bottom represents one of the posts supporting ODU’s elevated track, and the
green line represents the track. (Photo from Thornton, 2008).
Conclusion:
The problem of Old Dominion University’s Maglev train’s power consumption, due to levitation
and overcoming air resistance, can be solved with the use of superconducting magnets. These
cryogenically cooled magnets “[…] support a very high current density with a vanishingly small
resistance. This characteristic permits magnets to be constructed that generate intense magnetic
fields with little or no electrical power input”, thus reducing operational cost as well (American
Magnetics, 2012). Furthermore, the superconducting magnets could be placed on the bogie
underneath the train, effectively combining electromagnetic suspension and electrodynamic
suspension technology to overcome stability issues between the magnetic forces encountered
when testing and operating the train.
