MAGLEV TRAIN Here is some brief history on the maglev train in 1902 the train was invented by a man who goes by the name Alfred Zehden who originates from Germany . His idea of the maglev train wasn’t popular at first but after due time investors and engineers looked into it and up to this date still use his design of the maglev train. You may be wondering what does maglev mean , well maglev is derived from the term magnetic levitation it’s a method of transportation that uses magnetic levitation to carry vehicles with magnetics rather than the traditional wheels and axels. The main use of the maglev train is to transport people from one place to another using magnets and electricity .The maglev train is made up of a lot of electromagnets …show more content…

Ac motors are mainly use for larger aircrafts. There are two main types of ac motors , depending on the type of rotor used. The first type is synchronous motor , which does not reply on induction and as a result , can rotate exactly at the supply frequency or a sub multiple of the supply . the magnetic field on the rotor is either generated by current delivered through slip motors and also rings or by a permanent magnet. Other types od the motor include eddy current motors. AC /DC mechanically commuted machines in which speed is dependent on the voltage and the connection. Second type is a induction motor which runs slightly slower than the supply frequency. The magnetic field on the rotor of the motor is created by an induced current . when the rotor rotates, the stator conductors are cut by the magnetic flux hence the reason an induced E.M.F is produced by them, because the magnetic poles are alternative N and S , they induced an E.M.F and hence current is armature conductors which first flow in one direction and then in the order. The single phase motor operates in a single phase supply and for use on numerous application like ceiling fans and also refrigerators ,food mixers ect. A single phase induction motor physically looks similar to that of the three phase induction motor except that its stator is

  • Train Trip Marian Anderson Analysis

    456 Words  | 1 Pages

    During the train trip from Washington D.C. to Savannah, Georgia, it was difficult for Marian Anderson and her mother because they had to put up with racism, discrimination, and segregation while on that single train ride. Since they were segregated from the whites and the "white folk" had the more luxurious train car, the colored people were expected to ride inside the more dilapidated train car. The car that they were riding in was "dirty inside and out" and had "windows [that] were badly in need of washing, and the ventilation and lighting were poor." This means that the conditions that the colored people were expected to reside in were of extremely low quality. Not only that, but it can be inferred that people can get sick while on the train ride. The line, "...the air became stuffy and the windows were raised, smoke and soot from the engine directly ahead poured into the car." shows that people were unable to breathe properly while in the train car. The people riding the "lower class and colored car" would have to make a choice of either feeling cramped inside the "stuffy car" or feel less cramped but not be able to breathe properly.

  • Railway Electrification: In the Wrong Place at the Wrong Time

    1520 Words  | 4 Pages

    The Baltimore & Ohio railroad (B&O) was the first railroad to electrify part of its tracks, doing so in 1895 (Lecture Notes, 2/19/14). The electric locomotive was faster and cheaper than the steam locomotive, and produced no smoke (Lecture Notes, 2/19/14). This opened up the gates for electric locomotives to replace steam engines on their own tracks. Still, only a few American railroads electrified their lines between 1900 and 1950. Many American railroads failed to electrify their railroads due to the high initial cost and economic conditions, the lack of standardized electrical systems used for the railways, and corporate resistance (Bezilla, 42-47).

  • Understanding Electric Motors

    805 Words  | 2 Pages

    A direct current in a set of windings creates a polar magnetic field. A torque acts on the rotor due to its relation to the external magnetic field. Just as the magnetic field of the rotor becomes fully aligned with the external magnetic field, the direction of the current in the windings on the armature reverses, thereby reversing the polarity of the rotor's electromagnetic field. A torque is once again exerted on the rotor, and it continues spinning.

  • The Physics of Roller Coasters

    866 Words  | 2 Pages

    “A roller coaster is essentially a gravity-powered train (2).” Gravity is the weakest of the four physical forces, but when it comes to roller coasters, it is the dominant one. It is the driving force and what accelerates the train through all the turns and twists. Gravity is what applies a constant downward force on the cars. The deceleration or acceleration mostly depends on the inclination of the angle relative to the ground. The steeper the slope is, the greater the acceleration, and vice versa.

  • How Trains Impacted America

    2541 Words  | 6 Pages

    No one person can be credited for the invention of the railroad; rather there are many individuals who contributed to the railways final design. To begin, as far back as the 16th century, Germans were using horse-drawn wagons, pulled along wooden rails. These systems were known as “wagonways” and are grandparents of modern railways. By 1776, wooden rails and wheels had been replaced by iron. Eventually, the wheels became flanged, allowing the wheels to better grip the rails. The major turning point of locomotives was the invention of the steam engine. The steam engine was invented by three different British inventors, over a period of a hundred years; to give only one man the credit would be a crime.

  • Railroad Development in America

    2381 Words  | 5 Pages

    Before all of the new engines from Europe came to America, the railroad industry was very primitive. In fact the first railroad in America was only three miles long. It was basically a mining track from Quincy, Massachusetts to the Neponset River. The rails were made of pine covered by oak which was in turn covered by a flat iron bar. Construction of this railroad commenced in 1826 and was completed in 1827. The second railroad was started in January of 1827 and completed in May of the same year. The tracks were used for a coal operation. The tracks only went a short distance and worked by gravity and the force of mules.

    ...late 17th century, and beginning of the 18th century, transportation was favored by American society so much, the wealthier would hire chauffer’s to take people places. So not only did the motor produce a better and more efficient life style, it also created a huge business industry, as we know it today called, “valeting”. The actual motor worked like this. “Two cups filled with mercury would contain a magnet and a wire with one being fixed and the other free to move. Whenever a current was passed through the wire, the free moving magnet or wire would revolve around its fixed partner due to the electromagnet forces being produced.” (History of Innovation). This first motor was a prime example of the fact that movement could be created by electricity and electricity could be created by friction. This motor was the most useful and applicable invention in the 1800’s.

  • Cultural Impact of the Railway of Victorian England

    2439 Words  | 5 Pages

    At the beginning of the industrial revolution in England during the mid-nineteenth century, the railroad was the most innovative mode of transportation known. The British Rail system was a forerunner in railroad technology, uses, and underground engineering. Though the rail system was extremely slow at first and prohibitively expensive to build and run, the British were not to be dissuaded in their pursuit of non-animal driven transportation. The most advanced mode of transportation prior to the introduction of the rail system was the horse drawn omnibus on a track, called a tram. This paper will examine the rail system from a cultural perspective, presenting the impact the railway had on everyday lives in Victorian London and its surrounding communities.

  • Elevator Experiment Essay

    1581 Words  | 4 Pages

    The objective of my experiment was to observe how people reacted to a violation in the social norms of elevator etiquette. Generally in elevators, people fill in starting from the back, face the elevator doors, and rarely make verbal contact with others. Unless the passengers of the elevator know each other, conversation is sparse and often limited to small-talk. As a result of this, my goal in the experiment was to introduce a foreign behavior to the elevator, something that nobody would expect while going about their day. Thus, I entered a situation where a certain set of expectations was in place, such as the informal rule that individuals should stand (rather than sit) in an elevator, and violated those unspoken rules without acting in

  • Direct and Alternating Current

    480 Words  | 1 Pages

    Alternating current is always changing in direction and amplitude. The current flow in alternating current changes in even intervals. Ac usually changes in power and direction. The vast majority of power supplied for households and big business is alternating current. This is because of the ease of generating alternating current in alternators. The main concept of alternators is moving a conductor through magnetic lines. The change in the magnetic field around the conductor or vice versa makes electrons move. When you have physically moved either the conductor or magnet in a complete 306-degree circle you have produced one sine wave or one complete cycle. The amount of time it takes to complete one cycle is referred to as a period. The frequency of an alternating sine wave is the amount of cycles per second. Frequency is measured in hertz. One hertz is equivalent to one cycle per second. The frequency coming out of your electrical plug at home is 60 Hz. The peak value in a sine wave is the top voltage level away from zero. The peak-to-peak voltage value is referring to difference between the positive peaks value to the negative peak value. The effective or rms value of a sine wave is the actual amount you would use or measure using a multi-meter. In three-phase alternating current there are three different coils or conductors that produce three different sine waves.

    The Tesla coil was made by Nikola Tesla in 1891. Tesla was a scientist that believed the ground and Earth were better conductors than metals. Therefore, he created the Tesla Coil which was a device that could send electricity to appliances without cords or wires. This device was able to power lights or other things that required electricity from several feet away. The Tesla coil looks like a mushroom with a metal top and copper wire coiled around the center of it. A Tesla Coil if tweaked can make electrical currents go through your body, make electron winds, or shoot lightning bolts. Altogether the Coil was made so the world wouldn't have wires everywhere. Imagine a world with no wires, there wouldn’t be things you could trip over and no telephone

  • Induction Motor: What Is A Induction Motor?

    1118 Words  | 3 Pages

    Induction motors by the name, are AC motors in which they rely on the induction that occurs due magnetic field to produce torque in order to generate motion. So there is no force intervention in the starting or while operating the induction motor, as the main purpose of the induction motor is to convert electrical energy to mechanical energy, in order to operate other machines or appliances. The three phase induction motors are easily constructed and easily handled. The induction motor was first introduced in the late 19th century by a scientist called Nikola Tesla, in the early days, the induction motor had the same principle of operation and construction as today, the difference is that, the technology introduced new materials to fabricate wires and shafts and housing of the motor, thus enhances its performance and efficiency greatly.
