The MAGLEV Alternative
Joseph Milburn [MLBJOS001]Gabriel Andrews [ANDGAB002]William Mee [MXXWIL002]
Transportation and The Future
With an increasing world population comes more pollution, congestion and expense. World petroleum prices sky-rocket and productivity is crippled by inefficient transport.
MAGLEV Trains, based on electromagnetic levitation and capable of speeds of up to 500kph, are the answer of the future.

The MARKET NEED & END-USES
MAGLEV transportation will provide anyone and everyone with a new, reliable and fast means of travel. It will transform inter- and intra- city transport.
MAGLEV Trains will take ground transportation to new heights with respect to speed, capable of up to 500kph.
MAGLEV Trains make use of electromagnetic propulsion, lessening theneed for fossil fuels.
The MAGLEV Train Alternative provides:
The MAGLEV Train Alternative will provide a solution to the congestion and expense of travel, revolutionizing transportation of the 21st century.
High-speed transportation Less congestion Low noise & air pollution Cheaper, safer transportation
Job creation in high-technology, manufacturing and construction Economic growth The
AlternativeMAGLEV
Levitation is based on attractive force between electromagnets on the undercarriage and guide-way stator packs.
Superconducting induction coils are attached to the undercarriage and guide-way
Propulsion is achieved using a linear motor that alternates current in the cable windings to push and pull the train along
Linear Motor Principle: Alternating Field pulls and pushes vehicle forward
HOW ELECTROMAGNETIC SUSPENSION (EMS) WORKS
Magnetic Suspension / Levitation
Power is supplied by both primary generators and a limited backup battery.
The
AlternativeMAGLEV
ELECTROMAGNETIC SUSPENSION SYSTEM Stable levitation is achieved using height sensors and a microcontroller. The microcontroller communicates with the operator and/or base station. Propulsion is controlled by varying the current to the linear motor system The train may also use conventional “wheel on rail” systems
