Stator and Rotor how to make help needed!

[clflyguy]

@ Tom- Yeah, Sam's 6v golfcart batts are the perfect choice at this stage of the game- floodeds are much easier to monitor properly.

@ Michelinho-  It's CLFLYGUY

@ Infringer-
 
Forget steel rotors from Otherpower unless you just want to pay shipping on $80.00 of steel. Find a Brake Shop somewhere and grab a couple
of discarded disc brake rotors - They're FREE and the magnets stick to them just fine..

The template for the mags you can make for yourself with a compass, protractor and a piece of cardboard.... 12 mags, 30^ apart = 360^

So far I've saved you over $100.00....

The center pipe can be galv. water pipe, mild steel, galv. fence pipe- whatever, so long as it's straight.

Sheet of 1/2" exterior plywood for top, middle & bottom discs (airflow enhancers) and assorted other smaller discs yet to be discussed...

A gallon of your favorite color exterior latex enamel

There has to be four welds- the four 1/4"x2"x approx. 8" pieces of plate that the threaded rod that suspends the stator are bolted to,
and your buddies wire feed gun will do fine- just be sure to take hub, bearing and any lubricant off before welding.

Two hub assemblies- take a look at some of these I found at Northern Tool, maybe you can find some locally or cheaper somewhere

Study a couple of the early builds of the brake rotor alternators at Otherpower.

Later...

Sorry CLFLYGUY for the error  , I was on painkillers all weekend long (still on), had a blurry vision and mind.

Take care,

CLFYGUY,

Sweet deal bud looking good thus far rustolelum seems to fair pretty well hell folks have been doing paint jobs on there cars with it some had good success while others had issues but that alone says something aside from the fact that I have used it and it lasted fairly long even outdoors and its cheap to boot so that'll be what I shall use!

I may paint the barrels to slave off some of the wear from the sun if they are any other color then white. That is the color I will be using to reflect as much sunlight as possible.

   OK, I have to bring up one "VERY" important item that seems to be left
out of all the sites on wind. I have ask the question a few times and no one
will venture to answer but sure needs to be thought out carefully.
   How are you going to lower the two rotor halves together, safely? You have
12 pairs of 13000 gauss at a very small distance apart when in place. That
converts to one hell of a lot of force wanting to crush anything that gets in the
way. Namely hands and fingers.
   Make sure you have someone handy to help you or at least watch so if it
goes wrong can help you. I cringe when I think of two  2X1X1/2 grade 45 neos
that close.

   Since I could get no good answer, I chose to go with smaller mags and more
coils in a larger circle. When you look at the layout of the stator compared to the
rotor, you will always have 4 magnets and 3 coils. My mag/coil sets are 12/16
and the rotors will actually have 48 magnets on them. This leaves me a great
latitude on wire up of the phases. At the moment, I see 9 phases out to three
diode sets.

  Some folks drill a couple extra holes in the rotors for jacking screws. Personally the use of heavy welders gloves, the friction of the first rotors five 1/2"-13
threaded rods against the sides of the holes on the second rotor, and a couple paint stir sticks did the trick.... Along with five carefully measured & cut
aluminum tube spacers that held the rotors perfectly parallel to one another, (they fit over the all-thread between the rotors).
