This Thing represents a model which is a basis for studying radiant or flyback energy. It is a compact design. The original designs and applications for these motors should be credited to John Bedini and Ron Cole. I reworked this motor to make it easy for those across seas to source the magnets and hardware. It also has some upgrades. A good place to learn about this technology is here: http://www.energyscienceforum.com/forumdisplay.php?f=48
The moderators worked closely with John Bedini and understand this technology well.
Parts:
6 magnets: 40mm X 10mm X 5mm https://www.magnetexpert.com/rectangular-magnets-c35/40-x-10-x-5mm-thick-n42-neodymium-magnet-8-3kg-pull-p3790 also http://www.magnets365.com/10pcs-40mm-x-10mm-x-5mm-block-cuboid-rare-earth-neodymium-magnets-n50-grade.html for a pack of 10
12 M4 pan head bolts at least 10mm long for the rotor caps 6 per side
8 M5 pan head bolts at least 50mm long 4 per side
8 M5 pan head bolts for mounting the motor 4 top and 4 bottom (optional)
2 8mm X 22mm X 7mm skateboard bearings. I highly recommend ABEC 5+ or Swiss Bearings: https://bonesbearings.com/bones-reg-swiss-skateboard-bearings-8-pack
The wire and the circuit is up to you.
1 8mm shaft rod
3 5mm X 5mm disc magnets for reed or hall triggering (optional) https://www.magnetexpert.com/circular-disc-rod-magnets-c34/5mm-dia-x-5mm-thick-n42-neodymium-magnet-0-9kg-pull-p3558
Print with infill set at 30%..tops and bottoms .8mm...walls 1.2mm....2mm layer height.
You are contending with strong centripetal forces.
Please review https://www.thingiverse.com/thing:1676878 to have an idea how this should fit together. I use a table vise to press the two bearing ends together once I have the tabs lined up on each of the eight corners. This presses them together evenly.

This project contains an electrical function. Electrical shock resulting in injury or death can occur. If you are not experienced with working with electricity do not attempt this project. Know that some frequencies have been speculated to cause cellular disruption leading to cancer.
12/03/2017: The bearing holders had to be adjusted. The corrected file has been posted. It should fit skateboard bearings now.
