Someone on this forum has an alternator similar to Stans?,that could share the stator specs,especialy window dimensions,to calculate how much wire is alowed to wind,and aproximate the voltage output.My small alt.puts out 35v with 5v 0.8A at the stator.Komek you said you play a lot with all kind of alternators,maybe you find a ford big alternator to measure it,thanks!

Yes I got one, I'll make some measurements for you or post a picture.
These are 6 pole rotors.
One way to calculate wire to wind:
- decide what wire you want to wind it with.
- cut small pieces and fill a slot.
- 6.25" wire loop is (2 x pi) basically

Will make slot measurements later.

Thanks so much Komtek.You know that is a ford 1g big size alternator no?I speant a lot of time finding the exact one but no stator specs,cheers!

Here's some pics, not the best but this appears to be the same alternator as Meyers.
Stator core is 1 1/16" thick (slot length), average 1/4" wide and 7/16" deep slot , 6.25" coil should be correct and can be wound on a 2" outer diameter mold,jig whatever.

That is the EXACT one Komtek,the ''ears'' holes the vent holes,the fan,the back case bubles thats the one,the 1g big ford alt.Man i was searching for days for those specs,i can thank you enough.I am a bit confused with the measurements because in my country i use metric,so thats so strange looking rullers you have,so let me see what i undestand(see pics).can you tell the stators outer diameter?from what i measured with irfanview based on your ruler the OD was 160mm.Oh and if you want /can you take a picture of the stator with the windings on it to compare it to Stans,also the number of winds per loop of the stock one,sory for that many requests but i want to see how much voltage Stan rvic was puting out and if it worts the effort,because i spent 1week trieing to wind a hv stator with 30awg and i let you gues what happened......Thanks very much again Komtek!cheers!

Hy guys,i'v been working hard on rewinding an alternator,this time with 0.8mm wire20turns per coil,but the output was only 6.8v,crap with 0.8A into the rotor.The coils were wound in the same direction clockwise like in the pic.What i'm doing wrong?

This particular Ford alternator has 36 slots.
We make a coil group of 12 coils 20 turns each.
Did you do this?
Start slot 1 span to slot 4, next coil start slot 4 span to slot 7 and so on.
Also play with the rotor magnetic force, meaning maybe bring up the voltage/current for a stronger force in its field.

thanks komtek,thats exacly what i did 12 coils /20turns each,wound all in the same direction,output 6v,the laws of electronix does not work for me!:D

Now check your rotor slip rings.
Use emery cloth or something a little course fine grade and break any glaze on the slip rings.
Check the brushes and just lightly take any glaze off them.
Brush carbon will grind off fast so use 600 or higher sand paper just a couple swipes.

Then you should be able to get more dc on the rotor field.
