Bicycle Wheel Alternator

This is the Basic Stamp which I was going to use for the motor control.

This has changed now and the DSP is in progress...

It's the first time that NASA has done something useful

Beautiful post Z. Monkey thank you for sharing...

I am curious if anyone has tried axial flux on a bicycle before?

Howdy Y'all,

By Axial flux you mean where the coils are mounted vertically around the periphery of the wheel rather than radially like this configuration?  If you notice the date on this post it has been here a long time.  It is one of the first projects that I posted on overunity.com.

I would like to get some semicircular neodymium magnets for the wheel and build better coils that fit the radius of the wheel so that I can get better clearances, which mean better magnetization and better current output.  I also need to increase the mass of the wheel so that it produces more flywheel effect.  Long term plans for this one include developing a magnetic bearing system to eliminate the friction of the hub.  Then also using a DSP and MOSFET bank to drive the output coils to spin up the device.  Then use the same coils to extract the energy out again.  This eliminates the DC motor and drive chain system.  It is not really intended to be an overunity device.  It is just a platform to experiment with brushless motor concepts and flywheel storage of energy concepts.  Basically a cool physicists toy...

Blessed Be...

Wow, it's hard to believe that this gem didn't generate a single response when you first posted it!  Your ability to build stuff this elaborate leaves me very envious - well done!  I remember that http://www.theverylastpageoftheinternet.com/ used to link to a site where someone went to great lengths to try something similar using the Newman motor principle, with the intention of powering his home, so no expense was spared - unfortunately I have just discovered that "theverylastpage..." site is no more, which is a pity!  Anyone know what became of it?  Anyway, the elaborate Newmann build ended up only working 'sort-of'.  Not an easy nut to crack it seems...
