Brian’s Morning Newsletter for Tuesday March 17th 2009 Good Morning I’m going to give you a photographic newsletter this morning. There are a lot of images, so I resized them all, most down to 400 pixels wide and 35 kilobytes or less in size. I hope this works well for all of you. Remember you can go to http://outfitnm.com/alt-energy/wind-power/axial-flux-alternator and see the full sized images in the web page I created about yesterday’s projects..
I had this so close to finished and it disappeared, damnit. I was working on this at www.outfitnm.com for at least two hours when as I typed in the thousandth or so keystroke everything disappeared. No "undo" nothing I could do to make my work come back, it was gone, and I am out of time, so here is what I can quickly muster from the ashes. <br> Notes from Brian: Let me see if I can fix this up now that I am home from work.
Axial Flux Alternator
For starters, I setup a couple of saw horses in the yard beside the shop. Getting them level was simply a matter of using the mini-hoe to dig out the ground a little for the feet.
The rotors are laid out perfectly level outdoors .
Wooden disks were covered in wax to release them from the resin
we did both rotors at the same time and used the leftover to fill in the cracked dashboard on the BMW
Above you can sort of see me spreading the vinyl ester resin on the dash.
Jackson observes the already hard resin only five hours later in place on the wind turbine housing.
We got to try out the little bearing greaser we bought from www.etrailer.com after a botched order and we needed to add something to make the shipping more worth it.
The stator with the copper coils inside took a lot of reworking to get it to look this good. Next time we’ll be doing things differently. I have a section dedicated to the the stator. The bottom line is although ugly as sin this stator will work for our first try at building our alternator.
Kevin installs the 5/16 inch all-thread into the stator. We are pretty excited because this stage has been over a year in the making.
Alway have the book open at this stage.
There it is, the stator is mounted on the wind turbine housing and after a few tweaks to the adjusting nets on the all-thread the rotor spins freely!
Good view of the stator mounted in front of the magnet rotor. We gave the rotor a little spin and it produced 30 volts per coil set of which there are three, and this was with only one magnet rotor in place. Next we had to find a way to safely lower the second magnet rotor onto the alternator without damaging anything including our fingers, because there is a hellofa lot more force here than one might expect.
Since the Blacksmith shop di a bad job building the rotor disks we had more issues that we cared to admit created for us. At this point the holes they drilled for the jacking bolts to lower the rotor gently in place were drilled the wrong size and our all-thread didn’t fit in the holes, grrrrr. Time for a quick and safe plan "B". We used the polyester wedges for Jack’s Alaska Chain mill to gently lower the rotor in place. It worked like a charm.
Lastly, the second rotor was too close to the stator and was rubbing, We had to find out if our ingenious plan of using the wedges was going to work in reverse because we needed to remove the rotor and add a washer underneath.
Of course it did! The extra washer was all the extra space we needed to get the rotors to spin freely. After a few quick spin tests the alternator puts out a nice even 30 volts on each phase, saweet! Next we’ll break out the oscilloscope and check the waveforms, but that’ll have to wait for another day.

Your Quotes of the Day for 17 March 2009 Patrick, Bishop of Armagh, died on this day in 461, and has been regarded as a saint in Ireland since that time. The first known secular celebration of his feast day was a quarter-millennium ago, on this day in 1756 at the Crown and Thistle Tavern at New York City. Patrick was a great missionary, largely responsible for converting the Irish from their pagan heritage to Christianity, but the story about driving the snakes into the sea has no historical support and I’ve never heard any good reason why kids that forget to wear green today will get pinched! In his honor: a few quotes on Green and the Irish. Van ______________________________

Today’s Quotes: Nature is the true revelation of the Deity to man. The nearest green field is the inspired page from which you may read all that it is needful for you to know. – Arthur Conan Doyle, 1859 – 1930 Green is the prime color of the world, and that from which its loveliness arises. – Pedro Calderon de la Barca, 1600 – 1681 The Irish gave the bagpipes to the Scots as a joke, but the Scots haven’t seen the joke yet. – Oliver Herford, 1863 – 1935 Our Irish blunders are never blunders of the heart. – Maria Edgeworth, 1767 – 1849 If this humor be the safety of our race, then it is due largely to the infusion into the American people of the Irish brain. – William Howard Taft, 1857 – 1930 The English should give Ireland home rule – and reserve the motion picture rights. – Will Rogers, 1879 – 1935

Congratulations on yer whirly-gig, Got the pics on my email but not here. Didn’t look at google.
How about enabling avatars? I don’t like that little squiggly thing.
