It 'could' be done, but it would be complex, and prone to inefficiency or failure. Depending on how many phases your try to run, you would need a slip ring...
Ok, If you look at my video, I am not building a windmill, but rather something simpler. I will use multiple phases, and I will put the bridge rectifiers...
Hello My name is Jeff from NH and I know I do not have a Axialfux setup but on the blades, I have a Air-X and it came with a 3 blades setup and I went out and...
Do you think if I took off 3 of the blades and left 3 on of the longer blabes would be better?? I hope this summer to make a Axialflux setup. I hope to get...
I believe the 3 longer blades will be good. Steve Spence http://www.green-trust.org ... From: "Jeff" <Jeff@...> To: <axialflux@yahoogroups.com> Sent:...
Dave, I installed a drainwater heat exchanger to capture heat going down the drain and use it to preheat the water going into the water heater. This works all...
... When I used to live near Cleveland Ohio, we had a January, where the sun did not shine once, all month. Actually, the sunless period extended from late...
... I agree with Steve, three would be better but being longer will only increase torque, not speed. TSR(Tip speed ratio) refers to how fast a blade will...
Darald, Solar water heating maybe in the future. When I bought that exchanger it was about $300.00. Probably more now since the price of copper is up. If solar...
Actually I though I'd said that about our fall and winters... here near Cincinnati. Best would be a combination. I do like the heat recovery for the drain...
I believe it is interrelated, and, closely coupled. However... unless he is experiencing a failure to start in low wind (with the short blades) there is no...
What about longer cord airfoils ? Isn't this simply a matter of "square feet" or what the pilots call "wing loading". I.E. a wing 2 times as wide can provide...
I was reading one of the how-to articles, and, IIRC the author wrote that the disk-drive magnets needed to be cut in half, then stacked. Why ? I'm having...
yes, the fragment would still have north and south poles. there is no gain in stacking that I can see. if you needed to stack for some reason, just use smaller...
I'm not either, but I think there are two factors here in producing the power; RPM and torque. You need both. Just having higher torque at a low speed will...
Me either.... I just figured, if we want to draw energy out of moving air, we should try to understand the limitations of paddlewheels. suggested reading --> ...
we already have the speed we want. I thought what the OP was asking was would longer blades collect more power. the answer is yes, it can. The axial flux is...
Ok I guess I did it when I ask , Thanks all for you Info and will try the 3 blades that are longer and it will give me a faster start and power on it. Like I...
From previous replies in this thread... "As 3 blades are the most eff, if they won't do it, nothing will" "I like the way you think, Dave, but I'm not sure you...
All that is said below about Contra Rotation is quite correct, and was dealt with in the design of the Trimblemill 1976-78 A machine in N E Scotland has been...
Sorry for the tangent then; "the design is optimized for 650 RPM" MOST EXCELLENT ! with that info, and the KW rating & airspeed profiles for a particular...
That's all wonderful. keep in mind this is a axial flux discussion group, so some of your out of the box thinking may not be appropriate for this group. Steve...
It would be nice if some one had the plans for the most efficient, cost effective, setup. from the the wind turbine generator, wireing, batteries, and a...
