Hello everyone. I'm planning to eventually create our own power systems around this property instead of the gas generators we're currently forced to use. We're being denied utilities by the city and power company so we've had to be creative...
Anyway, the motor I really want to build is a axial flux type motor, but I do not want alternating current. I know that DC axial flux motors are absolutely a thing because many electric vehicles use them. What I don't see is people building DIY versions as generators. So getting the information I need is proving harder than I'd hoped.
So, my plan for a test version of this general idea will probably use hard drive magnets. They're by far the easiest magnets for me to get and I will be creative to make them work even though they're oriented the wrong damn way for most things. I will be putting them on an axle and then I'll spin them over my stationary windings. I plan to take the same pole for all the magnets and orient it so the disk they are on makes one big ring magnet basically. Its going to look really weird because the drive magnets are curved, but that will be fine for a test model. I'm using recycled motor wire for the windings, so this thing will be quite the recycling project.
Wiring the armature is more of a complicated topic though. What I think I want for best copper density is two rows of windings, one forming a smaller "inner track" and one "outer track". The exact shape and configuration of the inductors is definitely somewhere I need help. I'm assuming the wedge-style inductors common on DIY wind turbines here would be acceptable. I'm assuming air core is probably best for this job, but I'm open to suggestions. Wire gauge, number of turns, and exact dimensions of the coils is still undecided. I was considering wiring the coils in parallel, but maybe in groups of series parallel. It would be nice to keep the output in the 12V range, but even up to 48V is pretty workable. If the output potential gets a lot higher than that, I do have a magnetic DC transformer I invented that could be used(though I don't know how efficient it is yet).
The first version of this motor will be tested by compressed air through a "Tesla Turbine", so the rotational speed should be pretty consistent at a given pressure. So, basically the rotational speed can be set to whatever I want and kept there.
