I'm no expert, so this is all speculation on my part. The stator can have its output leads connected or not. Thanks Mike! They're great alternators; easy to make and as you say they work well. So in theory, I would be doubling the coil area that the magnetic flux penetrates, thus doubling my output. Better to have one big stator and then you can have twice the rate of relative motion between magnets and stator. Eddy currents from stray flux crossing any non-moving conductor, 3. IMHO, the calibration of your lathe torque is irrelevant to this non-linear situation.
Designing aimed the axial flux generator is placed into the single end of the side rotor in the machine and permanent magnets are placed into the double ends. The axial flux alternator or generator, is the heart of many DIY wind turbine projects.
Single Rotor or Dual Rotor Axial Flux PM Alternator
With a little Magnetic flux passes from one rotor to the other through. Basic Principles Of The Homemade Axial Flux Alternator If you are new to the. One Magnet Rotor Mounted to Hub Rotor and Hub Mounted on Tower Head.
Your alternator is 12 1" x 2" x.
Steven, Now you get my point. OK thanks. For dual rotor 16 pole I would use 12 coils. I can maybe help if you send pictures but the alternator is probably too small to be useful.
I did not understand the reference to the plastic disk. To make the stator produce a voltage potential, the rotor can be turned by the lathe.
Conference Paper in AIP. I tried a single rotor axial flux experiment on my Banki turbine. I couldn't get enough flux to get to cut-in at the low RPM so I integrated a store.
For example… we have 3 stators with 3 phases A, B, C in each! I am not sure how I would incorporate the moving metal backing on the other side of stators one side is no problem but not both.
The Bergey test is a good example.

I have done a lot of testing myself. After I posted the original message here, I stumbled across Internet Fred's site which also recommends using multiple smaller magnets if larger are not available.
«on: July 18,PM». I will soon have in my possession 1/2"x12" cylindrical N48 neos. need a gear system due to its design structure.
Key words: Axial-flux generator, Permanent magnet, Generator, Single stator. Double rotor.
Then there's the need for twice as many magnets vs. I have a small working model I can send in a pic. I made a write-up because other people wanted to see what I did; I can give you the link if you want to see it still getting used to this forum's interface. Note that there is significant data that above a certain WS, the CP starts to fall dramatically I would be interested in the results if anyone tried it this way.
I have done a page comparing the costs and performance of two alternators built using my recipe.
