I also mend everything and invent, excitement is spotting a skip full of useful goodies that folk throw away unaware of its potential value and other things it can be used for or just simply spares.good video😉

Yay just started watching been looking forward to this

[@gregmay9097]

Why didn't you spin the rotor with a drill and measure the output and rpm before and after the modification and compare the two? Also, wouldn't it have been easier to just put 6 magnets on each side to start with?

[@darrinrebagliati5365]

Reduce, reuse, recycle are only part of the solution. People always forget that adapt, modify, rebuild are parts of the whole. I like to tinker with things like this too. I have found a lightplant stanchion that I'm trying to aquire to add a wind generator to my RV for winter. I don't have the advantage of a piece of dirt to plant a pole in and here in Canada we don't get enough sun in the winter for solar to be enough. Looking forward to the results!

[@t.h.o.r.]

Awsome comment Darrin thanks for your support. there is a place in every town where the car vs pole victims go. - they have stacks of slightly damaged tapered pole sections. get three or four of those and reassemble them without the top curved piece and you have your tower. Mine was a 5m shadesail pole from a school, free. topped with a 2.4 m scaffolding section .

[@darrinrebagliati5365]

@@t.h.o.r. Have you seen the diesel powered portable light towers the use on road construction sites? With telescoping poles that fold down? I have access to a couple of them. They have been removed from the genset so the genset can power a forest service camp. I just need to figure out a base to have it stand on my trailer frame.

​@@darrinrebagliati5365 I'm off-grid 😻 in UK.. Incase you didn't know angling the panel's.. to noon sun (not necessarily 12 o'clock) is about 5 times more power. Regarding the turbine they don't necessarily need to be that high up, it's anything blocking the wind the same with solar.. One trick or game you can play is... Find the wind tunnel.. There are places.. buildings, tree's, hills and valleys etc where the wind gets funneled and becomes strong. Another thing I do forget to do is keep the panels clean.. give a wash when the panel is cool.

[@darrinrebagliati5365]

@@mySeaPrince_ the valley I live in doesn't get much sun in the winter, especially in the trees that I'm in. I want to get at least 40ft up to take advantage of the funnels in the trees around me. And they seem to be most powerful above 35ft here. In the summer I'm usually in a gravel pit somewhere and don't have to worry as much about solar because it's more open. And no trees around means wind can be at 20ft up easily depending on location. That's why i like the portsble light tower stanchion. Can adjust the height from 20-50ft easily.

[@basilkey2949]

I did a 1.4 to 1 chain drive and did get a little power out of it. If it was in a good wind spot it may do ok. I put 3 wider and little, longer blades on it. It still starts in low wind.

[@entertainme121]

I'm by no mean an authority on the subject of magnetism, but I appreciate your content and so will say that your attempt to increase output has likely hampered it. You've redirected the magnetic flux *away* from the coils. If you think of the flux like electricity that wants to move through the path of least resistance, by adding those magnets at 90 degrees away from the coils, most of the flux now travels along the path of the magnets and then through the rotor disks. You've likely heard of a halbach array. If you could remove all magnets and reinstall in a halbach array configuration you might see more output?

[@t.h.o.r.]

The next couple of weeks will see- depending on the wind. there is nothing today - just pelting rain. But my tanks are almost full overnight! haha. Ive asked 3 Ebay sellers to clarify the flux direction of their bar magnets so that I can get the correct ones in there. This isn't over yet lol.😁

[@fischrocket]

I have to second that. While one might think, that an increase in magnetic field (stronger magnets) would result in a higher generator output, there are more things to consider. First, and here is the biggest problem, the orientation/direction of the magnetic field vector. This vector (H in literature) is supposed to point in a particular direction. By adding your magnets (on the face of the rotor) you now have given this vector an additional axial component. Meaning that the magnetic flux vector (B) is now not directed as intended in order to induce current in the stator windings. Given an ideal system this might not cause much trouble. However, in addition the magnets on the lamination stack of the rotor now also influence magnetic flux within the rotor. The round holes in the lamination stack are there to reduce magnetic flux across the rotor. The added magnets now counteract this design and act as a low resistance magnetic conduit. So, I too can not see any way in which this modification improves performance. To the contrary, I see a lot of problems. Keep tinkering.

[@basilkey2949]

Waiting to see if what you did helped. Not pushing, Just wishing you good wind. If I add magnets, I will not do this. I plan to try a 1.4 to one gearing. That might be a little too much. Might be to slow but it has 5 blades. Not sure what these things should run at. But as fast as it could go it did nothing hooked up as it should be. I would be glad to see 4 amps like yours.

[@user-hl1tw8rs5g]

About 10~15% is lost in gearing.Direct drive is a lot more efficient.

[@MrToastedtoad]

the only. blade design that would approach 90% reliability would be a self adjusting blade design. thanks for the vid.

Remote NSW here off grid I like your work and the noise is a parrot maybe?

[@t.h.o.r.]

I have Japanese quail

[@basilkey2949]

Can't want. Could you see a change? I have one plan to add bigger magnets to it. Cut the rotor out and add n52 magnets but bigger. Well dipper inset. Same size on top.

[@t.h.o.r.]

I could not find the curved magnets- current challenge is finding axially fluxed bar magnets- everything seems face fluxed. Oh and no wind this week or next week according to the forecast. All I can tell you so far is that I now have very slight cogging felt at the hub but not out at the blade tips. It starts and cuts in charging at the same speed- but no amps readings yet

[@WhatDadIsUpTo]

I built my wind turbine towers such that they hinge and have counterweight, so I can raise and lower them with one hand . . . Even in wind. Even at that, they all simply turn transmissions, transferring the power lower to the ground. Much safer doing it that way. All my turbines pump air. I find it easier to make electricity using a consistent supply of air, instead of trying to second-guess Mother Nature.

[@michaelpolcino]

So did adding more magnets in the turbine generate more watts?

[@typhoonphan9487]

Can you tell me the size of the magnet?

yes mine was only $39 but the seller was an absolute wanker. Sent me another 5 blade hub then complained to me that I left bad feed back. even offered me $10 to change my feedback without them fixing the problem!@@dustinfrost5214

I recommend you a MPPT from Victron instead of your charge controller you have to switch off when your battery are full

[@t.h.o.r.]

Oh- when I have money things will be different. - everything here is done on a budget- thats what makes me resourceful

[@user-zm4yg9xv8q]

If you want highest efficiency, use a high voltage coil. The force required to spin it is less. Its the electromagnetic equation, then step it down to 12v and you have more power.

[@user-zm4yg9xv8q]

Something like 250vdc max. Smaller wires, more turns, less heat, more power from magnets.

[@t.h.o.r.]

thank you

[@dustinfrost5214]

Any updates on watts and amp improvement

[@t.h.o.r.]

hardly any wind in the last week- nothing to report that is worth a video till I can show the numbers. they just flash across the screen - it doesnt record figures

[@dustinfrost5214]

Ok do you have a wee amp watt meter hooked up to it

[@t.h.o.r.]

Its one of those blue >60v dc 150 amp meters that scroll through 4 functions continuously. Ill film it when its cranking - then slow down the playback so it sits longer on each reading and I can explain each reading. cos it just holds each number for one second. @@dustinfrost5214

[@dustinfrost5214]

@@t.h.o.r. hi mate just tried the 3 blade that was a wast of time it wasn't near as good as the 5 blade I cut my blades 3 inches and put all 5 blades back on major improvement getting 150 watts when before 80 was max and was and started getting fluttering blades not anymore now I have cut them down

[@t.h.o.r.]

Now that's interesting!- I never thought of shortening the blades. Did I say that I ordered a 3 blade hub and they sent me a 5! - they are not interested in putting it right.... The forcast is for 30 kph winds on wednesday/thursday so Im all ready for some filming @@dustinfrost5214

[@friedrich_k]

thats what i call tinkering without any knowledge.

[@t.h.o.r.]

and thats how you learn

[@kimmogensen5390]

this will proberly be so little that you can hardly messure the difference,,, rip those tiny magnets off file the slots deeper purchase some wider and deeper magnets (a extra fixation on outside of magnets can be done with strong thin tread and laqour

[@dustinfrost5214]

Any updates please

[@t.h.o.r.]

yes- Ive replied to several people here telling them how it now has slight cogging, but still starts well. Its autumn here now and after having it sit almost stationary all summer its doing its stuff right now in the dark My batteries are topped off even though its been grey and rainy all day and the solar hardly contributed. Because both systems feed the batterys its hard to quantify the turbines contributions exactly. But standing watching the screen on a windy day Ive seen that it now feeds in at 2.2 amps on occasion - It seldom used to reach 1 amp charge before I added the extra magnets. Its theoretical output is 4.1 amps at max wind speed. I did witness an actual event where the blades reached terminal velocity and fribulated and I was there to see a momentary 4 amps on the screen

[@2011BBSS]

Did it work???

[@t.h.o.r.]

I now have very light cogging and DOUBLE the amps when the wind is belting at 20mph. but still it reaches the point where the blades flutter at terminal velocity - so I think that it is as good as I can get without changing the blade setup. example: swapping to a 3 blade hub. I did order a 3 blade hub but the twats sent me a 5 blade hub and refused to replace it unless I sent the wrong one back at my expense.

[@dustinfrost5214]

A follow up please mate

[@t.h.o.r.]

Waiting for wind. Initial tests were good- 50% more power. but you guys need the video for proof so Im praying for wind- we are in the middle of a hot sticky summer right now

[@dustinfrost5214]

That's very impressive look forward to seeing the video

[@kostasgr8861]

Do you see any difference??

[@t.h.o.r.]

yes- but when I came to record the meter readings- It had gone past 99 hours and reset itself! so now Im waiting for more wind. Mid summer and 35C days and no breeze

[@PhonePhone-sf8te]

update?

[@t.h.o.r.]

its been summer- waiting for wind.....

[@kostasbobos6209]

After one month you didn't say what happened with your patend...

Yes I did- you just didnt watch the latest video Its short just to say that Im doing it and it was successful. the main vid will be filmed next windy day as my device does not log- only displays in real time
