Hello all .. I am new to the group so hope this is the correct place to ask this question. First... a little history about myself. I am retired. We live "off...
Hi Mac! Yes, Yes, 2kw, and yes. http://www.fieldlines.com/story/2007/10/26/141411/24 It's working absolutely great for us, with a steady 2kw output and a ...
Hi Trevor -- our turbine kit is quite comparable to anything commercial in that range of swept area (9-10 ft), like the Bergey, Whisper, etc. More info...
Hi Mac - (I hope I've not posted this twice... I tried earlier but it seems not to have taken after after a few hours) We recently built a 2KW alternator for...
To control the output voltage you need to regulate the speed of the diesel engine. Higher rpm=higher voltage, lower rpm equals lower voltage. When a load is...
Listeroids are governed to their design speed of 650 rpm. A perfect match for a Axial Flux Alternator. Steve Spence http://www.green-trust.org ... From:...
Hi Mac - We recently built a 2KW alternator for battery charing that's directly driven by my listeroid 6/1. I could probably have close to 4KW from it - but...
Dan ... Thanks for the additional info. I am currently running two Ford alternators limited to 50 amps output each to keep from burning up the diodes. I have a...
... This assumes that the connection is "delta", a "wye" can generate DC with only three (3) diodes, but it results in a DC bias in all coils. David G. LeVine ...
... Nope, you are not missing something. If the diode (and a microwave oven unit will not be suitable, it is high voltage, low current) prevents backflow, the...
... Mouser lists 14 Gauge Belden Magnet Wire for about $56/pound as P/N 566-8073 in their catalog. Most electronic distributors list similar products. A quick...
There is no field winding in a permanent magnet motor / generator. Steve Spence http://www.green-trust.org ... From: "David G. LeVine" <dlevine@...> ...
The axial flux is a wye, and is wired similarly to a car alternator, with 6 diodes. Some folks have played with delta, but wye is more common. See the diagram...

Hi Mac - ... When dealing with lots of power, 12 Volts becomes tedious.... ... It depends on the sort of efficiency you want from your alternator I guess. At...
Has anyone used a flywheel from a car engine for a rotor plate? Would take some machine work but might be worth while. These should be cheap and available plus...
... Often, the best place to look is your local motor rewinding shop. They buy on bulk spools and can sell you a small spool with no shipping charges if you...
... Pigott (SP?) style alternators have been built on brake rotors, sounds like the same idea. ... Actually, frequency shifts from power stroke to compression...
... My error, I didn't remember seeing permanent magnet, only DC and I thought I saw "field" mentioned. Ah well, CRS (Can't Remember Stuff) gets us as we get...
Some indicators: 1. This is a permanent magnet group 2. The subject line ... At least you didn't catch your hand in the woodsplitter ..... Steve Spence ...
Well I completely forgot the whole thread and I'm only 53, sigh. Just a youngen Anywho, can you tell us what the "Wye and Delta" stand for here? ... -- Brian...

... Wye, one end of each coil is connected to a common point. It looks like the capital letter "Y" Delta, one end of each coil is connected to one and only...
Hello all. I found this group by searching Google for Hugh Piggott and Otherpower about wind turbines. I'm sure I'll have lots of questions as I get this...
You can set a relay so that if the breaker pops, the relay is no longer energized, and shorts the turbine. I'd just skip the fuses ..... Steve Spence ...
Yes, it would unload the windmill to freewheel, very bad. We call that breaker the 'self destruct switch' if someone should accidentally open it. But, it would...
Kevin my partner in our axial flux project here in New Mexico, was wondering whether shunting the output would stop the blades? I thought not, because there...
