This design is quite different to any of my previous ones. It is based on both the Inductrac Train
and dropping a magnet down a tube. The train, or rotor, becomes a toroidal loop or ring made of magnets with alternating radial fields. The train runs within a toroidal tunnel made of aluminum.
Coils are arranged around the outside of the tunnel and drive the rotor as a BLDC motor.
Like the Inductrac Train the rotor is on wheels initially, and should lift off the wheels at a low speed. As the speed increases, the rotor should centralize within the tunnel or tube. The magnetic fields radiating from the rotor are sweeping through the stationary tube walls. The distance from the magnet to the tube wall needs to be as large as possible, while still having the magnetic fields extend into the tube wall. The inductrac Train when at maximum speed / lift also has minimum drag. The maximum height is reached automatically, where any further increase in height would lift the train field off the conductor track.
When my Toroidal Train further increases speed, the field created should increase in size or strength around the tube, and hopefully will interact with the Earth's Dynamic Gravitational Field and cause the entire machine to lift.
The radial field magnets for the rotor are a little bit unusual, but not expensive. Each Magnet is made from 2 cylinder magnets. These are forced together with like poles together.
