Maglev Trains the development of a novel maglev vehicle concept. This prototype demonstrates many of the key advantages of the technology which uses permanent magnets for levitation and does not require any moving parts in a track bifurcation. Key design features and performance characteristics of the prototype are described: the control system for stable levitation, the linear synchronous motor for propulsion and the method of track switching. Alternative system configurations and other applications of the technology are also briefly discussed. 1 INTRODUCTION The repelling forces resulting from bringing like poles of two magnets together is a commonly experienced phenomenon. The use of this repelling force to levitate a vehicle was considered early in the exploration of maglev vehicle technologies (Pollgreen 1964, Olsen 1965), but was largely discarded due to poor performance of the magnetic materials available at the time. As SmCo materials became available, the approach was revisited but again set aside by most due to the material’s high cost (Sinha 1987). In the 1980’s and 90’s NdFeB materials began to be developed as a low cost alternative and have steadily improved over time. Today, NdFeB magnetic materials offer a very economical option with more than adequate performance for use in maglev vehicles and their tracks. LaunchPoint Technologies, in collaboration with Applied Levitation and Fastransit Inc., has been developing a permanent magnet maglev vehicle concept which......

...A Paper Presentation On “Magnetic Levitation Trains” For [pic] ABSTRACT Imagine a train that doesn't touch its track and think of the potential for lower guide way maintenance costs as a result. Imagine a train that speeds along much faster than anything on the highway with a ride as smooth as silk. Imagine that train being capable of speeds higher than any other ground-based transportation system. Maglev can provide this speed and compete directly with airline travel. As stated by American Maglev, "Maglev means magnetically levitated and propelled vehicles. The advantage of maglev is that it can achieve very high speed and acceleration/deceleration performance because the vehicles essentially "fly" at very low altitudes - unlike trains or cars; there is no surface contact or "friction" to slow them down. More speed = more passengers." Only when we have real revenue-producing systems in operation will be able to prove whether this is true or not. In Maglev—which is short for MAGNETIC LEVITATION—high speed vehicles are lifted by magnetic repulsion, and propelled along an elevated guide way by powerful magnets attached to the vehicle. The vehicles do not physically contact the guide way, do not need engines, and do not burn fuel. Instead, they are magnetically propelled by electric power fed to coils located on the guide way. Indeed this is the beginning...

Meglev Train

...Magnetic levitation (maglev) is a relatively new transportation technology in which noncontacting vehicles travel safely at speeds of 250 to 300 miles-per-hour or higher while suspended, guided, and propelled above a guideway by magnetic fields. The guideway is the physical structure along which maglev vehicles are levitated. Various guideway configurations, e.g., T-shaped, U-shaped, Y-shaped, and box-beam, made of steel, concrete, or aluminum, have been proposed. Figure 1 depicts the three primary functions basic to maglev technology: (1) levitation or suspension; (2) propulsion; and (3) guidance. In most current designs, magnetic forces are used to perform all three functions, although a nonmagnetic source of propulsion could be used. No consensus exists on an optimum design to perform each of the primary functions. Suspension Systems The two principal means of levitation are illustrated in Figures 2 and 3. Electromagnetic suspension (EMS) is an attractive force levitation system whereby electromagnets on the vehicle interact with and are attracted to ferromagnetic rails on the guideway. EMS was made practical by advances in electronic control systems that maintain the air gap between vehicle and guideway, thus preventing contact. Variations in payload weight, dynamic loads, and guideway irregularities are compensated for by changing the magnetic field in response to vehicle/guideway air gap measurements. Electrodynamic suspension (EDS) employs magnets on the moving......

...are inefficient compared to other possibilities. Maglev trains have great potential for our fast paced world we live in; they can provide cheap and efficient transportation if further developed. This paper will demonstrate how maglev trains work with electromagnets. We will provide information about the history of early electromagnets. We will also provide information on the locomotion process, which is done through the generation of an electromagnet field by the rotor around the stationary magnet causing the torque from the magnet to pull or push it [1]. The paper will describe how each part of the electromagnet works. There are projects that we will discuss that helped further the development of electromagnets. We’ll inform the reader of current working models around the world. As well as describing the train and how it functions and various examples of the types of systems. We will also give information about the ethics behind the train. New technologies in today’s world must not only perform in the short term but also into the foreseeable future. Sustainability is one of the most important factors to be considered before adopting any type of new technology, and Maglev trains are no exception. Luckily for maglevs the way they work leads to high sustainability. This paper will talk about sustainably as well. Through this paper one will gather greater knowledge about electromagnets and maglev trains....

Maglev Train Essay

...Essay Thesis: Maglev trains will be the future of transportation providing benefits for the environment, society, and economic benefits. In our world today we have many problems. Problems that we are facing are environmental, social, and economic issues. This is due to the fact that traveling to work has become a hassle and when your using your car it also causes environmental damage. When people travel in their cars they have to fill it up with gas, which we have seen, gas prices increasing tremendously. This causes social problems because people don’t want to travel because it’s too expensive. The environmental problems we have are the fact that CO2 emissions are polluting over environment and causing harm to everyone. The result of this is global warming which is affecting our environment and society. Economic issues are the fact that importing and exporting oil is expensive. This is why we need to find an alternative. That’s why Maglev trains will be the future of transportation providing benefits for the environment, society, and economic benefits. Maglev trains use electromagnets, which make the train levitate. This causes the train to cause no friction and “may be a travel solution of the future”. This means that it doesn’t cause any noise pollution, which is great for ecosystems living around the track and also benefits society because then they don’t have to here the noise of the train, which most people find annoying. Personally I live right by the GO......

... INTRODUCTION MAGNETIC LEVITATION TRASPORT, OR MAGLEV, IS A FORM OF TRANSPORTATION THAT SUSPENDS, GUIDES AND PROPELS VEHICLES VIA ELECTROMAGNETIC FORCE Air flights are and will remain beyond the reach of a major section of society, particularly in India. Moreover there are problems of wastage of time in air traffic delays and 2 growing safety concerns. Trends in increased mobility of large masses with changing lifestyle for more comfort are leading to congestion on roads with automobiles. Besides, increasing pollution levels from automobiles, depleting fuel resources, critical dependence on the fuel import and due to a limited range of mobility of buses and cars the need for fast and reliable transportation is increasing throughout the world. High-speed rail has been the solution for many countries. Trains are fast, comfortable, and energy-efficient and magnetic levitation may be an even better solution.Development of magnetic levitated transport systems is under progress in developed countries and it is just a matter of time they make inroads to India as well. Therefore, it will be interesting to know about the science and technology behind mass ground transport system known as "magnetic flight". A LITTLE HISTORY In 1922 a German engineer named Hermann Kemper recorded his first ideas for an electromagnetic levitation train. He received a patent in 1934 and one year later demonstrated the...

...PROJECT TITLE: TEAM MEMBERS : Datta TEAM MENTORS: BASIC AIM: Maglev Rahul Agrawal , Chirag Gagrani , Akhil Lohia , Sohum RP Suman , Sachin Agarwal Our project is to build a miniature working model of MAGLEV, or more specifically, we will make a car that can be instructed to move forward or backward on a short magnetic linear track by means of magnetic levitation. BACKGROUND: Magnetic levitation (maglev) is an innovative transportation technology. It is sometimes said to be the first fundamental innovation in the field of railroad technology since the invention of the railway. A high speed maglev train uses non-contact magnetic levitation, guidance and propulsion systems and has no wheels, axles and transmission. The replacement of mechanical components by wear-free electronics overcomes the technical restrictions of wheel-on-rail technology. Compared with traditional railways, maglev systems have features that could constitute an attractive transportation alternative: 1. High Speed 2. High Safety 3. Less Pollution 4. Low Energy Consumption PROJECT MOTIVATION: Magnetism has fascinated humans for centuries. So we were looking for a project based on the concept of magnetism. The idea for this project came after discussing with the coordinators and reading a Scientific American Article that described proposed maglev systems around the world and their potential for future travel. THEORY OF OPERATION: Maglev is defined as a “family of technologies in which a......

Maglev Train

...ABSTRACT Maglev has been a long standing dream of railway engineers for the past century. These engineers envisioned a train that could float above its tracks. They saw the enormous potential for a train like this. The research on magnetic train which called maglev train was started in the beginning of the 1990 century. This concept lay dormant for about60 years. Then Japanese started their research on maglev train in the beginning of 1970 & constructed their first test line in 1997. German also started their research on maglev train in early 1970. It took them ten years to complete their first test line. The train works on the principle of electromagnetic effect. In this there is no friction between the train and track. The electromagnet on the underside of train pulls it up to the ferromagnetic stator on the track & levitates the train. The magnet on the side keeps the train from side to side. A computer changes the amount of current to keep the train 1 cm from the track. This means there is no friction between track & train. As it is high speed train compare to other types of train also noise level due to this train very less & energy consume is less, it is very convenient & beneficial to use. CHAPTER 1:-INTRODUCTION 1.1 History:- Magnetic levitation is the latest in transportation technology and has been the interest of many countries around the world. The idea has been around since 1904 when Robert Goddard, an American Rocket scientist, created......

Maglev Train

...How works a Maglev train? A brief review of magnets will help explain how maglev (magnetic levitation) trains work. Every magnet has a north pole and a south pole. Similar poles of two magnets repel each other; opposite poles attract each other. These principles govern the levitation of maglev trains. Permanent magnets are always magnetic. Electromagnets are magnetic only when an electric current flows through them. The north and south poles of an electromagnet are related to the direction of the current. If the direction of the current is reversed, the poles are reversed. In maglevs that levitate by magnetic repulsion, the train lies over the guideway. Magnets on top of the guideway are oriented to repel similar poles of magnets in the bottom of the maglev. This pushes the train upward into a hovering position. This system is designed for maglevs that contain groups of extremely powerful superconducting electromagnets. These magnets use less electricity than conventional electromagnets, but they must be cooled to very low temperatures—from −269 degrees Celsius to −196 degrees Celsius. In maglevs that levitate by magnetic attraction, the bottom of the train wraps around the guideway. Levitation magnets on the underside of the guideway are positioned to attract the opposite poles of magnets on the wraparound section of the maglev. This raises the train off the track. The magnets in the guideway attract the wraparound section only strongly enough to raise the train a few......

Maglev Train

...Intrpduction : Maglev systems are becoming a popular application around the globe. Maglev trains are popular in transportation stations in big countries like Germany, China, Japan and the United States of America due to the demand for high-speed transportation, as the general public transportation services become more congested with increase of population. Maglev trains are magnetically levitated trains that traverse in a very high speed, with only electricity being its main source of energy. The train propels forward without any friction from moving mechanical parts. It has many advantages with minor drawbacks. The basis of maglev trains mechanisms are magnetic levitation. This is achieved with the principal of repulsion and attraction between two magnetic poles. When two magnets have the same poles, it will repel with each other and when it has different poles, the result would be otherwise. There are currently three known maglev suspension systems. In this project report, we will be covering the basic principals of Electrodynamic Suspension Systems (EDS), Electromagnetic Suspension Systems (EMS) and Inductrack. The three suspension systems each have different characteristics and special features. While EDS and EMS both use only the interaction of magnets and superconductors, Inductrack uses coils on the track underneath the train body. All three suspension systems work under the same principal of magnetic levitation covered in this project report. The maglev......

...and even conventional trains seem to be too slow in comparison to planes. Now a new transportation mode has occurred that can clearly compete with planes in both speed and safety. They are called MAGLEV trains. The full form and the basic working principle of MAGLEV are called magnetic levitation. Many believe this mode of transportation holds great promise and offers considerable advantages. These trains use far less energy than other types of transportation and do not pollute. They can run at an average speed of 250mph that can climb much higher. The beauty of MAGLEV’S is that they travel on air. The consequent elimination of friction means much greater efficiency. Hence this gives an advantage over a regular train because there is no friction between wheels and the track. 2. WORKING PRINCIPLE The principle of magnetic levitation is that a vehicle can be suspended and propelled on a guidance track made with magnets. The vehicle on top of the track may be propelled with the help of a linear induction motor. Although the vehicle does not use steel rail they are still referred to as trains by definition they are along chain of vehicles which travel in the same direction. This is the definition of magnetic levitation (MAGLEV) train. As the frictional parts are minimum in this type of technology, the MAGLEV trains are known to have......

...scientist, created a theory that trains could be lifted off the tracks by the use of electromagnetic rails. Many assumptions and ideas were brought about throughout the following years, but it was not until the 1970’s that Japan and Germany showed interest in it and began researching and designing. The motion of the Maglev train is based purely on magnetism and magnetic fields. This magnetic field is produced by using high-powered electromagnets. By using magnetic fields, the Maglev train can be levitated above its track, or guideway, and propelled forward. Wheels, contact with the track, and moving parts are eliminated on the Maglev train, allowing the Maglev train to essentially move on air without friction. [pic] FIGURE[1] BASIC PRINCIPLE OF MAGLEV TRAIN Maglev can be used for both low and high speed transportation. The low speed Maglev is used for short distance travel. Birmingham, England used this low speed transportation between the years of 1984 and 1995. However, engineers are more interested in creating the high-speed Maglev vehicles. The higher speed vehicle can travel at speeds of nearly 343mph or 552 km/h. Magnetic Levitation mainly uses two different types of suspension, which are Electromagnetic Suspension and Electrodynamic Suspension. However, a third suspension system (Intuctrack) has recently been developed and is in the research and design phase. These suspension systems are what keep the train levitated off the......
