HI all,
Here is my first real axial generator in the building phase. I would like to introduce you to the rear disk brake and rotors of the GM cars of the Buick regal family. These are nice and reliable so I guess they should be pretty good for a mill. The mags are quite small on this one but i should get at least 100-150 watts out of the finished mill, maybe more.
Here you see the disk. The diameter is made for small machines but can be enlarged if using front disks with the same standard GM bolts pattern. I have 18 magnets and tough of making a 12 coils but I see they would span too wide for the small magnets.
I get no voltage with this coil arrangement. I know its too high, too much conductor with no magnet and the coil is 1.2 ohms, 40 or so turns of 14 enameled wire. I cleaned the tips of the wire with a dremmel tool. I turned by hand but never had seen the meter do anything. I have 2 more mags to cram in there but it barely fit. Can you guys make comments on the right coils for this applications?
And here is my small coils winder. These side panels will go round pretty soon. I have to make a nice coil form in some plastic piece or molded resin and a calculator counter using a monentary switch from a microwave oven. If it wiggle, I can just screw it in the bench.
Assembled. The black nut at the tip is just a spacer.
well, the car bearing and disk from these gm cars is really cheap and highly available here in canada and in the us. If you use it please send me some feedback.
