How to build a Dual Rotor Axial Flux Alternator PMA for a Wind Turbine

[75potatos]

Hello, how can i get in contact with the owner of this video?

[Pshtiwan77]

very nice and clear

[magna59]

Very nice jobs, you guys. Very elegant, and atleast you edit it down.

[ashtontechhelp]

Nice job, very clear.

Quick question though, why can Americans not pronounce Solder correctly, losing the L sound and pronouncing it as soDDer? Similarly, they pronounce Herb without the preceeding H. Weird.

[robojoepa]

Finally!! After watching countless videos this one showed me the details of wiring together the coils. Thanks very much and GREAT job.

[TheLucifer69]

You're awesome!



[DEWessonsax]

I have seen elsewhere that your coil size in depth, should be 1/3 the depth or thickness of your magnets, can you confirm and explain? Assuming this is an axial charged magnet. Thanks.

[samdekok72]

Fantastic videos. Wish i had found these a year or so ago. You might be interested in my Lenz blade concepts on my channel. Great vids. Subscribed.

[dsouzand]

should the coils be touching each other?

[carmatic]

i have a somewhat related question... is it possible to arrange the magnets so that all the magnets on the rotor face the same way, and all the magnets on the stator face the opposite way , so that they will repel and create magnetic levitation... and then generate power by passing the irregularities in the magnetic flux through the coils as the rotor spins?

[sergodinho]

Can you tell me the diameter of the wire and how many turns per coil , i live in portugal i don t know what means "ga" can you put in milimeters

[Cowcharge]

Is there one place where I can find all the math needed to design an alternator? Where do you start, with desired wattage? How do you calculate wire and coil size, number of magnets, gap between rotor and stator, voltage:rpm, and how many hp it takes to turn it under load? I've watched dozens of videos and been to dozens of wind sites and have yet to find any specific information. It's extremely frustrating.

[jotoew]

why are there 3 terminals?

[ovalnet]

Great coil design. My son and I have been having fun with magnets and copper. Have you made multi-staged stators? Stacked them in tiers?

[elizondo2000]

hello please can you tell me that the slides are made material? these metals are embedded in a circle where the coils are installed ...... thanks

[contactss65]

very nice and informative video! Ready for part 2!

[lrb1e39]

It would appear that, once constructed and put into production, there will be two disadvantageous aspects to the design that, perhaps can be overcome. One is the friction introduced at the axis...perhaps creating a frictionless axis to rotor design using permanent magnets in a concentric ring configuration. Second is the weight ofthe turbine frame/blade configuration...perhaps using composite materials or non-metallic, yet strong materials might reduce the weight bearing across the magnets.

[Thinker4Life]

I'm building a low cost vertical windmill type system and am hoping to sell them door to door. And start my own thing.. What is the output of this setup and how many RPMs are needed? And is there resistance at different RPM's at all or is it constantly free spinning? Can this then just be linked to a Grid Tie inverter? Can this coil assembly be purchased already constructed cast and everything?

[eloid777]

how many watts is this stator design? would twisting the wire improve the wattage can some comment

[eloid777]

how many watts is this stator design?

[eddieconnors]

Hi, we have a selection of renewable energy courses in our autumn Brochure.

visit imecofarm for more details. Thanks. Eddie

[073wajid]

hi

i have 1.18inch dia 5mm neo magnets.

i want to make a dual rotor system 12 mag on each plates.9 coil on stator.

what gauge of wire and how many turns do i use to get charging voltage in 10mph wind speed.

[wramosbarboza]

Very Very nice! Congratulations... A great job.

[websitemakerjonathan]

what guage wire ?

[yyykl]

Thanks for your video

[Methamorphomind]

Best explanation is impossible. 11/10. Thanks my friend.

[Ezlife2]

should the magnets beable to fit throught the center of the coild?

[Ezlife2]

how many puonds of Magnet Wire dose it take to make all of the coils? if it is 15 or 18 gauge

[TheDemocracyDelusion]

Sorry, I am having trouble finding the data sheet on your web site. I have registered and am logged in, yet I seem to be just going around in circles through your catalog?

I know it exists, I have seen it lol, I just can't get back their.

peace

[YoLninYo]

Thank you for such clear, concise and helpful video (from a vendor no less). This actually makes me want to buy more stuff from you guys instead of DIY ...

Good Job!

[leonesith]

This is impressive! Been searching the web on how to build wind turbine generator good thing that i found your video here. Simple explanation and design. Will start my project base on your design, Will post my progress here also. Cheers! Thank you! keep it up. - from the Philippines

[ph2oo]

great real real explanation tanks for educating me:)

[didyahearme]

neat-o

[MandLVideo]

Hands down, This was the best Coil construction video I have ever seen.

[whackitov]

most bodaciously awesome video guys! pay no attention to negative comments. i love it!

have been looking around trying to figure out how these things get connected to the house

[certifiedchrome]

How many watt did you get from this Generator. And did you use the coils with iron core for more Power? I used Aircoils and the Power is not possible to use. MFG Certifiedchrome

[xmodalloy]

Ok, Why are there 9 coild and 12 magnets? not 12 and 12 or 9 and 9?

[thegreenfiddler1]

Great vid. Thanks.

[salvino12]

hello I would come to know how can I find the steps to make one because I also thank the gentleman who builds not from any help hello

[mapwear]

I would love to make this in my shop but in terms of cost I think it's cheaper to buy a gas generator and just remove the engine, strap on a pin-wheel and Bob's your uncle.

[zogworth]

@mapwear When you find some blades that turn at several thousand rpm please let us know!

[Markozmajar]

Nice generator. What is the efficiency of your generator/altenator? Is it possible with any device to convert output current to 220 V, without battery. I am thinking to use generator in hydro aplication where is near constant power and RPM.

[awizardalso]

Markozmajar- Google 'induction motor generator', and search YouTube, as well. It appears that by changing a couple capacitors, a common induction motor can be used as generator to produce 120 volt AC power at 60 hertz. I haven't researched these much, but I would assume a 220 volt motor will generate at around 220 volts. Might be an alternative to designing and building your own alternator from scratch.

[Markozmajar]

Hi awizardalso.

I read in some article that efficiency of induction generator for 400 W output is very small (under 60 %) and belt gearing is needed to reach the right RPM (depends on number of poles). Thank you.

[awizardalso]

I know very little about designing an axial flux alternator except what I've found here and on the net. I do know that higher current levels need heavier wire in the coils and higher voltages, more turns. There's the problem. For 220V at any significant power levels you're looking at some rather large coils. Add to that larger magnets and you're talking a major endeavor here. May be more cost effective to buy a commercial generator over building one. Sorry I can't offer much more help.

[Markozmajar]

I will search for more solutions and maybe commercial generator will be the final option. Thank you again.

[meyouitube]

awesome that's what i was seeking

[fred30680]

Could you tell me why you have two coils of wire ? I thought it was one wire coiled 100 times. OR is it just to make faster ?

so you only have to wind 50 times ?

[allnewjacked]

Never mind...with my kung-fu grip, i made them fit

[jwwm2]

Absolutely first rate. Thanks for posting this.

[allnewjacked]

Im winding a set of coils now and finding it difficult to make them narrow enough to fit. Each coil is nearly 1/4in too wide and when I squeeze them Im concerned they will get too thick to fit into the mold.

[soulmj1]

how many tour for one bobine ?

and the section plaese

[IsaacB5679]

On the wiring diagram they are color coded blue, red, and yellow. It looked like the wires were wrapped around the outside.... so I'm guessing it doesn't matter much if a wire from a blue one is against a yellow or red one?

[wind2volts]

The wire is insulated....so they can touch.

[MTTProNetwork]

What size wire are you using in the video???

Nice Video clips by the way!

[wind2volts]

In this video, we are using 2 strands of 18 ga to make a single conductor which has a 15 ga equivalent.

[fred30680]

Please explain, how does that work ?

[salvino12]

hello I would come to know how can I find the steps to make one because I also thank the gentleman who builds not from any help hello

[Bronislawsky]

@wind2volts why are you using 2 strands, is it to get more amp and less volts then if you would use 70 turns of one strand ?

[Bronislawsky]

@wind2volts How many turns per coil do you make ?

[wyktron]

hello, I'm from Republic of Moldova, I don't understand everything in this video and I have a question ! After 20 or 30 spins we stop the Coil Winder, and after that - how many spins we must make to finish the coil ?

[pitchblack2773]

what adhesive do I use to glue the magnets to the metal?

[copperwrap]

I didn't see the wiring diagram on the website were can i find it?

Thanks

[mrquanta]

you gonna look for the "DIY tutorial" section.

[youngms44]

I rate this a 10 Excellent video quality and instruction. Keep making them if only have the videos on youtube where this good. You wouldn't have to spend all day wading thru crap to find a good vid to learn by

[wind2volts]

Thank you very much!

[michael970]

this video was very impressive.I hope you are a teacher of some sort .thank you for your time.

[wind2volts]

Thank you!

No, we are just regular shop guys.

[djpole76]

yes, nice video!

[lad18913290]

this was awsome!!!

[joeusa1776]

Great Video!

One of the best "how to do it" that I've ever seen!

Thanks for posting it!
