PROJECT SUMMARY
The goal of the project is to design a model size train to will be levitated and propelled by electromagnetism. A special magnet array called a Halbach array will be utilized along with a linear synchronous motor to make this train operate.
STANDARDS
• ENVIRONMENTAL STANDARDS
– Reduction in pollution in the area where they will be used will out way the increased pollution crated by power plants to power the trains.
• SAFETY STANDARDS
– Must prove that the new technology is safe to use.
TRAIN
• Made out of aluminum to minimize weight
• 4 rows of 8 magnets arranged in a Halbach Array
• 2 rows for levitation
• 2 rows for lateral guidance and propulsion
• May or may not have speed sensor. This will be determined later
TRACK
• 2 aluminum guide ways
• Wires will be wrapped around guide way to provide the levitation circuits
• A G scale model railroad track will be laid between guide ways to provide support for take off and stopping.
• A linear synchronous motor will be attached to the track to provide propulsion
ELECTRODYNAMIC SUSPENSION
• The magnets on the train produce currents while traveling in the guide way. This uses repulsion to guide and support the train, but will need a support for “landing” and “takeoff” since EDS does not work below 25 mph on a full size train. The minimum speed for levitation will be determined later once the train is built. It has been determined to be a function of magnet size and weight.
PRELIMINARY WORK
• Almost all time has been spent on research
• IEEE Transactions have been very helpful
• No track calculations have been made. The train has to be built first to determine weight of train.
PREDICTED TIMELINE SPRING SEMESTER
• WEEK 1 - BUILD THE TRAIN.
• WEEKS 2-4 - FINISH DESIGNING TRACK AND BUILD IT.
• WEEKS 5-12 - TESTING AND DESIGNING A CONTROLLER.
• WEEKS 13-16 – PREPARING FOR FINALE PRESENTATION.
