Building a Wind Generator using a Car Alternator 

😂

wasted alternator, steel pieces and PVC pipe. it's 1\10 man

I agree definitely 10/10 on engineering skills. Maybe this footnote will assist others and yourself while you look for a way to change the drive ratios. I haven't built my own turbine yet because I'm still working on other projects that are required to come first. Anyway refrigerators in general use 300 to 800 watts of electricity and between 3 and 6 amps at about 120 volts. A 1hp well pump uses 750 watts. If it operates on 220 volts Alternators need to spin about 2,400 rpm at idle, their maximum output is above 6,000 rpm but not to exceed 8000rpm. Best wishes and good luck!

​@@stevenwilliams2601Could it just charge a battery like Tesla wall then use it when there's an emergency?

@@kingdavidson7430 So far the commercial home wind turbine only produces about 100-150 watts per hour per unit with average wind speed of 4-5 meter/s, and cost ranging $1500-5000 per unit (the good one, or famous one at least), break even twice than solar panel, ranging 15-25 year.

@@stevenwilliams2601 Gear ratio of 27:1 with Planetary gears stacked in 3 could help. Might need to search other DC motor / electric generator in reverse that has 6 or 8 poles.

You guys are the reason we love to share our work and learn new things.

@@DIYKingSaM thanks man .

No.

can you explain how will it increse the power

A large gear (say 60 teeth) takes longer to do a full rotation than smaller gear (say 12 teeth) will. I have seen this work and will increase the rpm, unfortunately the way that this turbine is set up it would require a rework as the blades would me the large gear and there is no option to gear it like a mountain bike in configuration. If you can find an old series from the Discovery Channel called “The Colony” they do it in season one.

wish I'd thought of that .. ;) .. " charge a super capacitor " ..

At night?

@daveapplemotors that is the reason behind the super capacitors, but the solar panels are primarily intended to provide energy to the system for the excitation current during the initial period from a dead stop to operating speed. Once the system is generating power it will keep the capacitors charged. Now assuming that the capacitors become depleted after sunset, you can either have an auxiliary battery or a connection to the primary storage batteries through all relevant circuitry.

Could you give some idea/details of these strong magnets? The ones i found in computer HDDs do not last due to rust. Thnx

Great job. Please develop a part 2 of this video and please advise the Brand name of the Alternator, and the part no. Or the motorized application ( which vehicle you “borrowed” it from ). Thanks !!

What type of motor you wanna use? Liam F1 Archimedes blade is dope. Gear ratio of 27:1 with Planetary Gearbox stacked in 3 would be great. How about vertical wind turbine?

No!

Indeed, your thoughts are worth reading. I hope you will soon get your hands dirty building one. We love to get such comments and that's why we together with you all bring this channel to the best possible projects that we can

Hi guys it is of very good job but I do not know what is the wind turbine, if you have any good of generating more power you can become a new company to sell your product on a lower price so that every Indian can purchase.

Use one from a diesel - these run at half the rpm :)

@@wombatg0 Really???? I would love to see you try to back up your comment. Just for comparison, the alternator pulley ratio on a Cummins Diesel is 3.22 which equates to an alternator RPM of 8,050 with an engine RPM of 3,000. Typically, The standard automotive gasoline engine alternators have their full output rated at 6000 RPM but can continue to spin up to 12,000 RPM or more without any additional increase in output.

@@PH_INFO_101 I believe 3000rpm for my motorbike

Well said mate 👍 and it's hard to rotate the blades if they add gears, better with Permanent magnets ;)

Yes we are looking for these magnets, hope to find the right ones soon and get the next part .

If I'm not mistaken the hoverboard motors u used in previous vids have n52 mags in.. try removing them. Or. Being a diy channel old hard drives.. they each got 1 in. . And they should be wide enough for that stator

You must be 127yrs old, you can remember the output of the first alternator installed on a production model vehicle and the phase out of generators in auto use. Tell me, was that soon after -ve earthing became the standard and 6V was phased out haha. Meant in jest, but seriously your figures are way off. Electrical load demand on modern vehicles now with bluetooth this, sync that, infotainment, screens, high power audio, heated everything from glass, arse, to mirrors, 2 billion times the computational capabilities of the Apollo moon lander and more ECU's than the space shuttle means alternators in standard 12V vehicle regularly approach and exceed 100A rated capability. I'm sure you probably don't need a maths lesson so I no need to throw power figures around except to say that's significantly more than 350W. That alternator was commercial 24V (not my area, light motor vehicle for me) so current rating would be inversely proportional for the same power, handy for that type of project working with less current . The vehicles generally have high electrical demand also (did you see the size of that sucker?) starting a high cc diesel and feeding a couple of 25kg+ 200Ah or so batteries, so I reckon if they shared the spec that thing is easy good for 75A, at a charging voltage of say 27V, so 350W?? Oh, and by the way, I think you underestimate the power of wind and fluid/aero dynamics. Yes is was rudimentary, but the spinny thing was plenty huge enough to drive it (with some gearing). Nearly 30yrs ago a friend used an old steel bladed radiator fan (adjusted pitch I assume) no bigger than 18" with a scrapyard alternator driven by belt mounted on the roof of his garage (come man cave), and a standard 12V starting battery as storage/smoothing/capacitance to run a CB radio and car stereo (maybe some lights, I cant remember) and in a mild wind it would power everything without draining the battery ;)

@@bobbobovich4356 Hi Bob. Well done, I'm 128 next birthday. It's all candles and a ruined cake for me. Too much irrelevant stuff in your post, mate. F.Y.I. the power available from any windmill is proportional to the CUBE of the airspeed passing through it. It's the VOLUME of air that does the work, volume being a cubic measurement. The one in the video would run the alternator nicely in a category five hurricane (about 256 kph), but quickly self destruct. At normal wind speeds it wouldn't rip the skin off a rice pudding, there's not enough kinetic energy in the small volume of air passing through it per second. Gearing it up won't help. Try pedaling a bike up a steep hill in high gear if you don't believe me. Before eager beavers spend their hard earned money on a dodgy project, they should understand the cube law importance in windspeed, because it limits the maximum energy available. Commercial wind generators only work because they have huge volumes of air passing through. Now excuse me, I'm off to finish a homework project. Cheers, P.R.

A 100 watt car alternator is heavy duty, right. 350 watts?

@@daveapplemotors Hi Dave. Good point. Wattage varies with requirements of the vehicle. My "ballpark" figure of 350 watts probably applies more to a bus or long-haul truck generator running extra lights and air conditioning. My point that you can't get any more power out of an electric generator than its power input (vee belt, windmill) puts in is correct however. Inserting gearing between the drive and the generator will not increase the amount of power that can be extracted. If it was possible, perpetual motion machines would be exist. Cheers, P.R.

But the older days are long gone. So, today we use an AC alternator.

Thanks bro

A cvt transmission is the best option, the simple version that uses no control circuitry, is commonly found in snowmobiles while there are automotive versions. But with the right application of a snowmobile clutch/ cvt pulley is the easiest option that i can think of.

Put on a heavy flywheel , use some external power to get it going first. That's my theory anyway!!

What's your gear ratio? Acquiring Planetary Gearbox seems tricky. Check out Archimedes blade of Liam F1

No, do not use gears.

Was this your first video?

No, do not use gears.

Unfortunately, you learned how *NOT* to make a wind turbine ...

It needs to spin 2200 rpm to function normally, and for full power it needs to spin more than 6000rpm but not above 8000rpm for too long because it will shorten its lifespan if it will not damage it, so in conclusion car alternators are pain in the ass if there are used for another purpose than in cars

No, do not use gears.
