Oh
but a dull permanent-magnet rotor axial flux wind turbine actually save you 50% or more on
your electric bills could this same ten-foot wind turbine actually be built by Joe average
does the mechanical duckfart sparks I think so hello I'm Scott Brown with green wind and other
home energies coming in for a landing here these are just some drawings I drew up show you how
I've done them here in a second this is a brake disc rotor don't ask me which one it is but this
one badly worn we aren't going to use this one the reason I show on this one is these on the side all
these little vent holes to keep the brake rotor cool there are 36 of them that's divisible by 12
and also divisible by 9 and that's a good thing that helped me draw all these radial lines that
would come out from the center these are just some pictures of how I decided to get my magnet
size and also the size of my coils the coils that I show on this one are not the ones I'm going to
use actually the ones I'm going to use are going to be a little bit different shape they're going
to be pretty close to the inside of the coil is going to be pretty close to the size of the magnet
just a little bit tapered in towards the bottom you see here I've got 14 gauge magnet wire I've
clipped them and straightened them out very very tight that way I could sit there and put them down
and get actual size of what my coils are going to be by knowing how wide so many layers of magnet
wrapping is going to be and then the thickness as well all this is documented so this is not
the actual drawing that we're going to be using just this little slide show here there's some
measurements of some lines I'll get into this and we'll draw a whole brand-new and I'll show you how
to draw this up really fast those five dots in the Centers for the lugs a good thing about this is
you get a nice hub spindle and bearing and then - brake disc rotors and 24 neodymium-iron-boron
magnets 1 inch by 2 inch by 1/2 inch and 12 of them are going to go on each of on each of
the rotors and then they'll be facing each other and we'll show you how to cast the stator like I
said this is just an introduction to us we're not really getting into everything here I hope to have
centimeters and everything else for you I thank you very much I'm Scott Brown with green wind
and other your home energies hello I'm Scott Brown with green wind and other home energies a little
few things around here show you a few things this is a neodymium-iron-boron magnet it is 1 inch by
2 inch by 1/2 inch notice this nickel plating here which actually protects the magnet seems
as neodymium-iron-boron is very unstable and it wants to corrode very fast this is probably
from slapping or letting don't let anybody play with your magnets because it'll mess them up this
once this nickel plating gets messed up and what it's going to do is going to corrode underneath
and eventually your magnet might come loose so be careful with these and these also if you'll notice
on my desk there's no sharp tools of ferrous metal of any kind aluminum is okay Oh copper stainless
steel is this actually sticks to stainless steel people say stainless steel is not magnetic it sure
is just not as much but anyway show you safety here number one when you come up to put this on
you'll stick it up on the edge like this it's much easier now this disc has been planed or it
has been put on a lathe and milled out leaving a 1/8 inch lip you put these magnets on you're going
to he takes two thumbs get it on there now it's not going to come this way no matter what you do
that's why that 8th inch lip is there we're going to get into this right now I'm going to take this
off and when you put these on you usually want a template that holds these that separates them
someone you put them down that will try to go into each other this is a good way to get them off grip
it really tight and roll it and now it's off I'm going to put this one away for a second that's a
good spot don't let kids play with your magnets and usually you want to use gloves this surface
will have to be reclaimed again with a the surface laughs to be re-cleaned again with a non residual
cleaner look at this this is very thin profile all the way from where it bolts to the hub to the edge
of the disk now mine which I should have planed this side all the way down left eighth inch lip on
there we go it's about right I'll take this piece of wood I'm going to show you something
I might just go ahead and make mine a little different than most people's I put this down
there I've got about an eighth inch lip or an eighth inch gap there and this is going to be
the thickness of my stator material and then the other one goes on the other side I might
just do it like this since this don't ask me what what bra what brand or what model make
that this brick this came from or the other one is the same I don't know I got them out of the
scrap I got the hub and spindle and everything and that's what we're going to be working with
for now I got this close put the magnet on it drew it this is going to be on here and then
this is going to be the shape of our coil right up to the edge and I'm taking the black right
off the lines and then I'm going to taper in and how much depends on when I do this next drawing
I'll do that with y'all on camera and then this one goes on and a crank runs through and this
becomes our coil winder and it'd be pretty decent and here's the wire we're going to use this is 11
pounds of 14 gauge double insulated 200 degrees Celsius magnet wire some people call enamel wire
and it's all copper and that's what we'll be using and I'll show you these drawings here
this red line goes all the way around here is where my brake disc rotor comes to and
yes it's also going to be close to the outside of my magnet and then my coil has to run out
you seen with the pieces of wire that I used to sit there and measure across and find out where
they're red I did a few other ones on the backside here here's the size of my magnet here's one I was
thinking about the inside of the coil shape being this way then I was figuring this one
this is the one I'm going to do and I'm going to taper the inside in another couple things you got
to do when you're designing you got to figure out that you'll have one magnet in the middle
of your coil and your next magnet is going to be over here this one will be north facing up
this one's going to be south facing up so your flux goes around and the same thing around this
way this gives you a lot more power on your coil if your magnets are right up against each other
like that because you got too many of them you're not going to get as much out of it you're wasting
a lot of magnet and I'm going to show you another clip an old clip to show you what the main deal is
about wise magnet youth and full circular path and then row the next video we're getting into
building and doing it all what it basically comes to is the the flux comes in this way
goes over here and comes back out so with these if I had two magnets sitting here both of these
magnets are twice as strong and then with the other rotor on the other side magnets against
magnets pulling towards magnets is a lot stronger than magnet pulling towards steel and you see how
strong this is pulling towards the steel so you never want to get your arms or your fingers or
your hands anywhere in between these magnets or the magnet rotors and you never want to store
these within the full frame of what you see on this video if this is what you can see that's
too close I'd keep about two foot two and a half three foot and don't bring any tools one tool can
hit hit the magnet rotor over here and be close to the other one pull them two closer together
and they're sliding and slam and if you're in the middle of it you just lost your arm these
magnets can break your fingers a whole bunch of with the multiplication of the full magnet flux
circle of the full magnet flux circle becomes a very dangerous thing many many pounds of pull
you might as well drop a car on your arm or motor anyway I'm Scott Brown with green wind
and other home energies many good things to you and yours I'll get this magnet off here
good thing to use gloves good I don't know where mine are at right now I just want to
get this magnet off there were other magnets on here I wouldn't be doing this that's for sure
Thank You boats I'm Scott Brown with green wind and other home energies hello I'm Scott Brown with
green wind and other home energies and building some 4l60e transmissions of the friend of mine
pulling him out and drop in a minute than make it a bit you didn't need these these are two rings
that come inside one of them and I looked at a must saw the inside dimension right here where
this could be screwed down nice and easy and attached to something else I've got 16 magnet
positions around and 16 magnet positions around on the other I tried to bring one side close
a little touch and letting these down gentle the thing there's lots of room in here keep it
clean for the pension basically they ain't coming apart I did it once before just for giggles and a
lot of having to move all the magnets but show you something why these magnets are so strong
is they're going through here and all the way over here back down here and back around again
a full circle of magnetic flux saying here and here and here all the way around about the only
way to get this apart without really risking chipping the steel or damaging it really hard
you're not going like this move the magnets move around to the other side now for the one inch
by two inch by three quarter inch the big ones imagine the force that that would be comin down
don't want to get pinched by that it's like taking these two and stacking them here and
also taking these two and stacking them here making these ones twice as powerful
in these was twice as powerful that right there smart way to use magnets
get everything you can out of them let me show you something about this before
we finish up none of the magnetic force is leaving the ring and the decent size value
watch the closes make sure all night I think we're close enough for any disease farm at
watch these man just had a RZR night sitting on the desk earlier
razor knife under attack this thing that far away stop brown with green
wind and other home energies we'll get into wine in Sakura
