... leftovers from previous jobs and the rest is tubing and pipes for the frame and stand. This is just a toy to show people that we are blessed with WIND AND WIND IS POWER TO BE HARNESSED. FOR FREE. I use ferrites, 75 x 50 x 25 (24 per alternator) on the serious jobs, and having imported many of ...
Usually arc or wedge are widely used in wind turbine. Block magnets can work out well too as all these magnets need to be assemble together to products the magnetic field.
Gentleman, may I comment on a general observation please: I notice that most guys wanting to work with wind turbines are clamoring for rare earth / neodymium magnets, mainly because they not only shine nicely, they are extremely strong (lets face it). Are all aware that they ...
... at distributed power applications November 18, 2014 Paul Dvorak The next generation of the company’s permanent magnet, direct drive distributed wind turbines is now available. At 60 kilowatts of rated power, with a 24-meter rotor, the recently launched NPS 60-24 can produce substantial amounts ...
In view of the electricity shortage and load shedding / frequent power outages in PAKISTAN a group of investors have decided to setup Low Cost 500W to 1500W Wind Turbines (PMG) manufacturing facility for the homeowners throughout PAKISTAN (starting from Karachi -Sindh).
... very long way to go. You can choose to help save the environment no matter where you live, because no matter where you are the sun shines and the wind blows.
That is high. I wonder how well it would work in reverse? My guess it would offer a lot of resistance, and there may be a lot of static friction - i.e. it would need a lot of torque to start it spinning. A worm gear will not work in reverse at all!
What voltage do you intend to get from the generator? How far apart will the magnets be? You are using very small magnets and very few coil winds, which means you will need to get a high RPM to get a reasonable voltage.Normally that means shorter blades, otherwise the tip speed gets too high. I thin...
... postings, and your name comes up all over. Are you the main guy on this forum? I would greatly appreciate any info you can give me on a suitable wind turbine. I live in Kimberley, and I have already installed a 2400w solar array, complete with Outback Charge controller, 2 x 3kw Inverters, a 660AH ...
Hi Jay, looks great! You can't use capacitors alone to increase voltage. You can make a circuit using a coil, a FET, and capacitor, which is called a DC boost converter. Or you can try increase the rpm to get more voltage. Once you get 13.5 voltage you are good to charge a 12V battery.
... turbines, like the large turbines attached to an AC grid. For a standalone turbine feeding into a DC system, the rotation speed can vary with wind speed. Another option is electronic - a variable DC-DC convertor driven by a microprocessor which optimises the DC voltage, and thereby the rotation ...
... stood for a long time so I'm sure I'm not going to get any voltage out of them, as for the de-sulfator there are plans in The Poor man's guide to wind mills maybe I could try build that and try it out on these batteries.Have you seen that or heard of any results from that De-Sulfator he talks ...

Even I have got wind farm and I prefer wind energy over soolar.. It is easy to maintain and more efficient.
Great going man,.., Even I do have plans of insatlling solar and wind farms very soon.. I think it is the best way in contributing towards saving nature.
... 2009 and again in 2010. That shouldn't have kept we away from this site but my first turbine also got blown out of the sky. I sort of gave up on wind energy. My solar geyser and PV panels have been eminently successful. I hate failure and I hate to give up. The broken turbine lying in my garage ...
... know how hot the stator gets - I have never monitored it. Of course, there is a neat factor in that the hotter the stator gets, the harder the wind must be blowing, which means the stator is naturally cooled if it is exposed to the wind. Some like Greystoke on this forum will be the oen you ...
... my product at all. Our turbine will produce 100% of its own capability at any given moment and yes, perhaps its only utilizing a percentage of the wind hitting the sweep area but as far as I'm concerned that's not important. Much like a claim that one only receives 59% of gifts on Christmas morning. ...
I built a wind turbine a couple of years ago but the voltage produce was only 11 volts so never did anything with it. tried with only 2 blades and got the rpm up but my furling was not good so the blades ripped off, now I'm thinking ...

... curiosity and because I'm often accused of being completely mad, what would be the best way to create a stator that would burn up in any strong wind, ie. if I used really thin winding wire, would that do it. Hope this provokes some thought, I've seen water cooling on industrial stators but not ...
... to our current understanding of Physics (c.f. Betz), the maximum power that it is possible to get from that area, at an arbitrary 10m/s (a strong wind!), is about (at sea level, so you would get a bit less up there) 0.35 * 1.33 * 1000 = 464.6W This is at an impossible 100% efficiency. At 7.2km/h, ...
Hi Everyone. I have casually browsed through these pages and am impressed with the knowledge they offer. I live in Johannesburg where the wind leaves a lot to be desired. As a handyman and kinetic art hobbyist, I stumbled across an idea for a new propeller design that takes full advantage of ...
