I am interested in building a generator of my own, but I am new to all this. I have read otherpower.com's website, pretty much all of it. But I still have a...

Welcome to the group! I've interspersed some more info after Steve's comments. DAN F http://www.otherpower.com/ ... We use an optical tachometer to check each...
Hi! I am Vishwas Gokhale Pune India. While discussing axial flux generators ,you have been discussing all the time of coupling to a wind turbine. I am...
Our goal with these units is to apply them to any type of motivator, whether wind, steam, human power, or engine. We can help you with this. Steve Spence ...
Greetings, I am in the visualization phase of home-built wind power. If built, I would need a 200 foot wiring run from the wind generator to the battery bank....
... The question is not of efficiency, but of cost. Let's assume single phase 24 volt runs and 50 Amperes. The wire losses for 100 feet would dictate 2/0...
I would keep life simple. Your wind turbine operates at very low frequency which will probably make the transformer less efficient. It's also probably a 3...
Thanks folks, good food. Yes, 20hz AC single phase winding is pretty low frequency at say 100 RPM, and would get even lower in weak winds. So, I will wind...
... I, on the other hand, tend toward a techie's solution. Assuming a wind machine which can supply 50 Amps at 24 Volts (which is not a small turbine, I am...
... Hi Butch. David L's wire sizing math is right on -- he sums it all up by saying "How much power will you be running peak? How much do you want to spend...
Thanks Dan! I'm starting to understand...design for a balance between minumum power expected for say 75%? of days, and the resultant available power on the...
Hello, What is the best way to increase the power output of an axial flux machine, scale everything(diameter, coils, magnets) up or add a second set of discs...

Hello We have a 1 kw windgenerator in India, made from plans from Hugh Piggott, made with the help of a friend. We are making our second windgenerator now. I...
I prefer keeping the batteries and inverter in the house, for environmental reasons. Neither work at -40 degrees .. I don't mind a bit of loss in the wiring to...
I just "discovered" axial-flux alternator for windpower this weekend. I regret not coming across it a few years ago - I'd have a wind-farm up by now! I always...
Hi, this is my first post here so I'll introduce myself, I'm Brian, a guy who knows alot about boat building and nothing about electricity. I'm giving myself a...
... First you need to start with data. Volume of water per unit time Drop of the water (height from initial inlet to final drain) After this has been...
After my last ramble, I thought I'd add some math/numbers Take your flow rate per 1second... Let's say you've got 1gallon/second.That's 3.78 litres per second,...
It seems to me there's a bit more to it than that. Consider for example two extremes. 1)The generator requires more torque than the wheel can provide (after...
The water wheel is a gravity engine. The rim speed represents lost head. I use the 5%rule. I allow 5% for a process. Fopr example the wheel is 10ft in...
responding a second time to my own posts.... I guess if a wheel carries the a given amount (mass) of water a given distance(m) in a given time(s) then that...
I have two windmills I have built for my dad one with Jerry blades and the other with Hornet blades. Neither have an alternator yet but dad is working on it....
... Well, yes, there is, but for overshot wheels the ancients (people of my grandparents' generation) worked it out quite simply: The torque generated is the...
Ok I see where you guys are coming from, build the wheel and then build the gernerator to suit the wheel. That makes sense, I'm not sure how I'll measure the...
Had a thought on this to share. What about a magnet on each spoke and a arc shaped panel with three or more coils on it mounted out near the edge where the...
... Simple answer, as long as you build a non-cogging (windmill friendly) alternator, you can live with oversized. Remember that the torque to run an...
Hi, This is about "Tower Height and Location" problems in related to Small wind Turbine. I had personally experienced difficult time due to practical problems...
