yes. likely. however, it will be hard to do it evenly, and may cause a great imbalance issues. also, the size matters too. 1.7 m dia wind wheel will catch more wind power than 1.3 m dia wind wheel.
the controller goes on the brakes after 200w are reached... that is not the outcome I want, so I need to put the different resistor on it. Default 400 watt 1 Ohm resistor - it brakes the turbine completely up to almost the full stop... and then the system has to wait 10 minutes to release it back to the production. Which is a pity scenario, as a single nice gust may block you out for a complete 10 minutes. So my plan is to actually make it kind of slow dump load, via putting a 500-600watt resistor of 25-30 Ohm, so it can take some excess power (1-2 amps), but will keep the production happening. However, my only concern for now is will it be able to bear all the load if the batteries are fully charged, and I will eventually have to test it as well at some point. about the enormously high winds - these blades have its certain limit too. since they have that high lift angle element near the hub center - it will naturally (aerodynamically) slow it down as well from the enormous rotation.
Your plan sounds good but my doubt is that thouse bigger blades get more wind so that it starts rotating way sooner with little wind. The problem I see is that when the controller brakes the wind turbine, the little magnets inside the stator might not be strong enough to stop the strengh of thouse bigger blades. I hope I am wrong
@@JoseAgustin-hq2pl yes, you are right theoretically. however, please check here: th-cam.com/users/shortsOMz419FyKBg this is my short video is in ukrainian, from my other channel, but you will figure it out just by the looks. to the right - default gen (8mm thick stator, 8 mm height of the magnets), to the left - the upgraded one (25mm thick stator, 25mm length of the magnets, moreover, the magnets are thicker 0.5mm as well). so, the generator is still more powerful than this 1.7m 3-blader-hub, so I am confident it will do the brake job decently.
OK, you have me thinking. The blades are only 81 cm with the link I went to. That's 31.8 Inch's US. I have built a turbine 36 volt 160 watt hoverboard with 3 blades the same as yours. It's the first motor I bought and is not used. I have not put it up yet. Not expecting much. Wiil see. Thaks for the info. That is the blades you are using on the mod-- turbine?
yes, here are the 81 cm blades on the mod turbine, those that are default for M3 (I will launch the video today). and the link I've given you earlier is exactly for these blades (with hub and cone or without, it's up to you to choose a package)
yes, I am. the default one is taken off since that initial gen upgrade video. this upgrade generator already shown 200 watts peak, and that is on my test setup, with many-many imperfections.
the main outcome is that that new gen needs the M3 factory hub and blades (like tested in the video) in order to work properly. all the links are in the description in case you are interested
My takeaway is that wind turbines are worthless. How much is the cost with the upgraded generator and 1.7m blades? How much for controller? You are getting only a few watts from 10Mph winds, it would take storm speeds to get anything decent.
Cost? WT - 28.9 Upgrade gen - 90.3 Blades with a factory hub - 71.94 Controller - 72.34 Expected monthly production in my area 8-14 kWh. I fully understand the values and the costs, and the solar in the end is 5 times more efficient. However in winter time the wind turbine is almost as efficient as solar, and is 6 times more efficient than any fossil fuel generator (diesel, petrol)... And well, I don't have to remind you that russians have destroyed a lot of our generation capacities, so there will be very little of grid energy during the winter time. If we have constant power outages now for 4-6 hours per day, in winter that outage time will be way more.
@@ModernUkrainianHomestead These are Euros prices? Is the production so low in the video because your batteries are already full? What is the expected output of the little windmill in this video?
Prices in USD. That was just a test, and there were many not properly done things, like cable too thin, tower too low and on the wind-shaded side. I'm currently in process of mounting it all correctly, check my latest video please, all the small wind turbines will gain some decent height and a proper cable too.
Expected output for the wind turbine like this (it is very similar to M3) is 8-14 kWh monthly. I claim them to be 400 real watts wind turbines. But we'll see everything in real action quite soon.
Hi. Great installation ! :) Bravo ! ! !
+ SUB :)
Regards - Paul P.
thanks! but that's rather for fun.
the great one (3.2m FT-2000L2) still has to arrive yet
Can you add more cupping to each blade of 5 blade using a heatgun?
yes. likely. however, it will be hard to do it evenly, and may cause a great imbalance issues.
also, the size matters too. 1.7 m dia wind wheel will catch more wind power than 1.3 m dia wind wheel.
Very good idea for producing more in low winds, but you have to test now if the wind turbine is going to be able to brake in high wind.
the controller goes on the brakes after 200w are reached... that is not the outcome I want, so I need to put the different resistor on it. Default 400 watt 1 Ohm resistor - it brakes the turbine completely up to almost the full stop... and then the system has to wait 10 minutes to release it back to the production.

That is another story! 😅 And a completely different wind turbine. Well done.
yes, this is an absolutely different toy now
