IntroductionIntroduction  

Bullet trainBullet train is a system of transportation that  is a system of transportation that uses magnetic levitation to suspend, guide and uses magnetic levitation to suspend, guide and propel vehicles from magnets rather than using propel vehicles from magnets rather than using mechanical methods, such as friction-reliant mechanical methods, such as friction-reliant wheels, axles and bearings. Bullet train is a wheels, axles and bearings. Bullet train is a means of flying a vehicle or object along a means of flying a vehicle or object along a guideway by using magnets to create both lift guideway by using magnets to create both lift and thrust, albeit only a few inches above the and thrust, albeit only a few inches above the guideway surfaceguideway surface

This train uses superconducting electric magnets in This train uses superconducting electric magnets in the vehicle to levitate and propel the train. These the vehicle to levitate and propel the train. These

magnets are cooled by liquid helium or liquid magnets are cooled by liquid helium or liquid nitrogen. This means that once electrified these nitrogen. This means that once electrified these

The magnetized coil running along the track, called The magnetized coil running along the track, called a a guidewayguideway, allowing the train to , allowing the train to levitatelevitate between 0.39  between 0.39 and 3.93 inches above the guideway. Once the train is and 3.93 inches above the guideway. Once the train is levitated, power is supplied to the coils within the levitated, power is supplied to the coils within the guideway walls to create a unique system of magnetic guideway walls to create a unique system of magnetic fields that pull and push the train along the guideway. fields that pull and push the train along the guideway. The electric current supplied to the coils in the guideway The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity of walls is constantly alternating to change the polarity of the magnetized coils. This change in polarity causes the the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds forward, while the magnetic field behind the train adds more forward thrustmore forward thrust

The electromagnets on the underside of the train pull it up to the ferromagnetic stators on the track and levitate the train.

The magnets on the side keep the train from moving from side to side.

A computer changes the amount of current to keep the train 1 cm from the track.

Propulsion System

The system consists of aluminum three-phase cable windings in the stator packs that are on the guideway

When a current is supplied to the windings, it creates a traveling alternating current that propels the train forward by pushing and pulling.

Page 12: Bullet train

When the alternating current is reversed, the train brakes.

Different speeds are achieved by varying the intensity of the current. Only the section of track where the train is traveling is electrified.
