Ok boys and girls,
After having seen many commercial turbines fail, underperform and otherwise not life up to expectation I have decided it is time to put an end to this sad state of affairs.
For an analysis of my latest disappointment please see
diysolarforum.com
I see no other option than to take it upon my self to DIY a VAWT and alternator that actually works i.e. that outputs an insane ® amount of power at low (safe) rpm.But as you might have guessed by the title I probably can't do it alone. The title has changed but that is not to say I do not need/respect help
I will be referring to the components in the thread above with a prefix of crap. So when I say e.g. crap coil I mean the coil of that cheap Chinese alternator.
The crap stator is a 3 phase 36 coil (12 coils per phase) radial flux variant.
The crap coils consist roughly of 68 - 70 winds (+-136 - 140 turns) at +- 16cm each totaling of about 11m per coil x 12 coils = +-132m of copper wire per phase.
The crap wire it self has a diameter of 0.4mm.
There are 12 poles in the form of sector magnets with an, as of yet, unknown tesla strength. I will be figuring out a way to measure it sooner or later. I changed my mind, I will not try that as it will mean extra equipment that I am not interested in for now. NO the magnets we are using here are far!!!! more powerful
I will be using an rpm for testing of 60 so that I can easily spin the alternator by hand with a reasonable consistency. At that rpm I hope to get a usable output already if at all possible but in any case not faster than 120 rpm, which should output at insane (TM) levels, else risk injury or worse if the, yet to be constructed, blades fling off.
when spining the crap alternator at 60 rpm there will be a 6 Hz oscillation in the crap coils. With the crap rotor having a diameter of 8 cm.
Now here comes the fun part. I am contemplating building the following 3 phase axial flux alternator

Having 48 x 60x10x5mm magnetic poles at a 35 - 40 cm radius.
I have 1mm enameled copper wire that is about 71m long.
1 winding (2 turns) of each coils is about 30cm totaling in about3.6 7.2 meters of 1mm coil wire per phase per 1 winding.
The alternator will produce an oscillation of 24 Hz while running at the reference speed of 60 rpm.
Now should I try and match or supersede the total crap phase wire length or should +- 71m be adequate for the new phase coil wire length?

Cheap chinese horizontal wind turbine, an in depth exploration.
