Hiya Guys,
Just waiting on a few parts to arrive then I'll be making my first dual axial flux wind generator. I intend to do a log in here on the progress and the finish will be a DIY guide to making one yourself. This thread will be used as a log and as I progress along a new thread will be done in the RE Projects forum for the DIY instructions.
The one I'm making I'll be targeting for the 3-4kw range @ 24 volts with 4 metre diameter blades and one can scale down for a smaller generator.
I'm waiting on a trailer hub assembly arriving so I can get the bolt hole measurements then I'll be getting 2 350mm diameter 10mm thick steel plates laser cut. The reason for the laser cutting is if cut using an oxy torch the plate will certainly buckle slightly and this is what we don't want.
The concept of the dual axial flux generator is 2 magnet plates with the opposing magnets facing N-S so they attract then a stator is in between holding the coils which generate the voltage/current. I'll be using 50x15mm round N52 grade nickle plated Neo magnets with 12 magnets on each disk. The stator will be 9 coils with 3 coils in series to make a 3 phase output, to hold the coils a mold will be made and either high temp epoxy or fiberglass will used to make the stator.
Once the generator assembly is made the mount will be made to suit the tower I'll make and for the blades I'll use my mate's idea and show how to make 2 metre long blades using a chainsaw.
More to come....
Cheers Bryan
