hi everyone. ive been reading here for some time now and i have changed jobs that allow me to start on my wind mill. at present i live in ohio south east of...
And why wouldn't you expect real help here? Many of use are experienced wind turbine builders, even though this isn't necessarily a wind group. It is an axial...
I'm not in ohio, but the wiring of a axial flux alternator is pretty simple. There are typically 9 coils in a circle. every third one is connected in series,...
I've never used disk drive magnets. The magnets we use are bigger than would fit in most disk drive. I've heard of folks using magnets from microwaves, but...
Thanks for the information. I've just learned that I may have access to a large number of used drives and wondered if there is any interest in the magnets...
Generally, hard disc drive magnets are too small to be of much use except in tiny science-fair type wind turbines. Old, giant computer tape drives (the kind...
This was a very busy weekend for the Green-Trust and Woodhenge teams, as The Science / Discovery Channel film team arrived to do a photo shoot on Wind Turbine...
How does someone figure the number of turns of wire in a coil to get a specific voltage, i plan on using 14 guage wire the target voltage is 8 volts per coil....
I have looked on the Science Discovery channel on Sky but don't see mention of the Green Science series, do you know if it is shown on Sky in the UK? ... -- ...
35 turns (per coil) is 12v per set of 3 coils, 70 turns is 24v, 140 turns is 48 volts. the thickness of the wire determines the amps it can handle before it...
RPM does affect voltage. Which is why with 5 foot blades we are shooting for 650 rpm at 25 mph or so. it will spin at the correct rpm even at lower wind...
Steve, What's the approx centerline diameter of the magnets and coils for an alt like that? Lee ... From: Steve Spence To: axialflux@yahoogroups.com Sent:...
Steve, My most usable wind speed is 11 to about 15 MPH and I intend to use a 24 Volt battery also. What would 7' blades do to the RPM in this wind speed range....
I don't believe the series has started yet. The hosts are still on the road filming. maybe the series starts in November? I'll keep everyone posted. Steve...
longer blades means more output. should startup sooner as well. you can go thicker on the mold. You will have to experiment with the wire sizes. Steve Spence ...
I have seen coils that people have wound that have all different shapes. Some round, some oval and some pie shaped. This may be a dumb question, but does the...
... I am under the impression that the space inside the coil is the size of the magnet so that one side has passed the magnet before the other side crosses the...
How would one go about design an axial flux alternator for lower speeds? Wind speeds in my area, though consistent are not fast. Thanks, SK ... slower ... ...
the higher the number of coil turns, the higher the voltage. if turned slower, a 48 volt unit will put out much less (12 to 24). experimentation is the key. ...
Hello SK, The V.A.W.T. I have designed will turn with power in low wind areas, however; the RPM on this vawt and most vawts is relatively slow. The way we get...
Steve, As someone who is about to build their firsy alternator and trying to sift through all the info available I would like to ask a big favor from all those...
