DIY Wind Turbine - WindBlue DC-540

This little film shows the making of a wind turbine that is based around a WindBlue DC-540 PMA. The turbine was made in two days using some great tools and with a clear plan in mind. It is currently mounted on a 4m mast with three guy wires. Output is connected to the battery bank via a diode. Charge control is handled by a Xantrex controller and dump load. Maximum unloaded voltage is 68v, not measured the current yet. This is not a WindBlue endorsed video, I am simply a customer who ordered the DC-540 from their web site and had it shipped to the UK.

I have had lots of views, not that surprised that there are so many 'experts' out there and the quality of the comments on the video kind of reflects that. Not interested in any more 'you should have...' or 'it would be better if...'. To all those who are just taking a look, thanks. For the experts, look at something else, please.

Open circuit volts are of no interest to anybody. Its the power we're interested in.

@thra5herxb12s - Look at something else then :-)

hi how did you get the wires to go threw the middle as ther is no hole ? it is nice to see a video that shows how to make it spin on its aksis so thanks for that

[glennjobson]

@mrkenickie1 - There is a hole in the center of the machined part I used, it is made out of a solid bar of stainless steel that was turned to fit the top of my tower, then a 3/4" hole drilled right through the center on the lathe.

what can you run of the power this produces ?



[honeybees1]

could you use a car alternator and do the same thing?Cool stuff thanks.

@glennjobson Nice try keep up in positive attitude, and I suggest do research

for aerodynamic in terms of blades thanks..

[thra5herxb12s]

@glennjobson Sorry. Thats not what I meant to say,what I meant was I would be very interested to know how good this is compared to my overpriced under achieving Rutland 913. I would like to see 12a in a regular wind instead of 800ma. Huricane Katrina only put 300mv into my battery bank in 10 hours.

not very efficient... that seemed like a ton of wind just to get it started.

Very nice job on all parts. If I may make a suggestion as some have - You need some larger blades to provide the turning torque for your PMA. Try a well made metal 3 blade rotor or one of those five bladed carbon fiber blades. Either with about 1.5m in diameter. It will pick up at much lower wind speeds and give you a 'much' better average output in all wind speeds. You will be surprised of the output difference you will see from the PMA then. Those PMA's are a good bit of kit.

@torimantena nop, not unless it has been modified. stator needs rwound for more voltage and armature needs replace with a permanent magnet one.
