Axial flux generator

Before I go any further I have to give credit were it's due; this wouldn't be possible without Hugh Piggott and the original Wind power recipe book.
Above is the first drawing of a basic axial flux generator. Keep in mind that dimensions will change before the final prototype is completed.
The red section (stator) contains 9 copper wire coils encapsulated in epoxy and stays stationary, mounted with a bracket on the back. The coils will be wound by hand using the tool described in an earlier blog. I'll post pictures of the finished product as I go.
The blue sections, front and rear are "magnet rotors". Each steel rotor will contain 12 Neodymium magnets epoxied in place and is mounted to the center hub. The magnet rotors rotate using the kinetic energy in the wind (or pedal power, or water, or...). As they pass the copper coils the coils interrupt the magnetic flux, picking up a small amount of electricity.
The ultimate target of this project is a turbine that will turn at approx 200-250rpm and produce around 800w-1000w of electricity. But it needs to be built from easily found parts so it can be produced in rural areas with limited resources.
So stay tuned, as this project moves forward so will the blog page. I intend on posting all of the steps involved in making this project, as well as the results from the testing phase this fall.
