Nice video.
Finally!! After watching countless videos this one showed me the details of wiring together the coils. Thanks very much and GREAT job.
You’re awesome!
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.
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.
should the coils be touching each other?
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 ?
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?
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
@wind2volts How many turns per coil do you make ?
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.
why are there 3 terminals?
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?
@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 ?
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
very nice and informative video! Ready for part 2!
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.
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?
how many watts is this stator design? would twisting the wire improve the wattage can some comment
how many watts is this stator design?
@VWRabbitdiesel
They make these things called gears, they do this wonderful thing that makes something spinning slow, spin something else multiple times faster!
Amazing, isn’t it?
That should be right but this wind generator only hit 12 volts in strong gusts and didn’t go much over that. It seems that the treadmill motors are best geared up rather than direct drive.
@belgrademachine Nice so you have to spin that thing @600 RPM to charge?
Try changing the motor. I got a 180 VDC 4700 RPM from an old tradmill. Thats 26 RPM to make 1 V, which is very good.
@belgrademachine 14.8 amps @ 850rpm good luck hitting 850RPM
@helloman1976 It is running free with no load in the video and reached about 6 volts at one point. What you can’t see is the house upwind about 8 feet away so its not a straight line wind. I did test the motor in a drill press and got the following: 4.45volts, 4.3amps @ 255rpm, 8.7volts, 9.5amps @ 500rpm and 13.75volts, 14.8 amps @ 850rpm.
@ripadisc
Thank you
How much power is it putting out? How many amps?
nice job man
