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
