okay we fished 77 turns the thickness of a piece of plywood that's half-inch that this stator is
going to also be a half-inch the plywood is actually 1530 seconds due to planing at the
factory to make it nice and smooth well at that 15 30 seconds is seven pieces of 14 gauge wire
side-by-side fit in there just right so 7 times 11 means 11 pieces of 14 gauge wire because I'm
doing the 24 volt system put this right up against the edge of my form of my magnet that I drew and I
draw them a line and the same thing over here and you can see I've already done this had a
few bad takes with the camera you draw your lines and you draw your line all the way on
out past where you think the coil is going to be because you'll round that off afterward but
the thing is this line right here is the edge of the parameter that this coil can fit in and that
would be a little bit smaller than my magnet due to that this makes sure that your coils will fit
and here it just barely touches the edge but I'm going to go ahead and bring it in just to give
myself a little bit of room for error sometimes the wires don't all just line up perfect like
that someone can do like this they take up a little bit more room as you wrap it lined up
neatly but don't get over fast Didius the coil shouldn't take you an hour to do it should take
you maybe 5-10 minutes if you want to sit there and align each piece up and then tap your wire
and line in it's gonna take you forever it's a headache and you're not you're going to miss the
joy of building this anyway and have no coil perfect really doesn't change its performance
okay the next thing is to draw the we're all the magnets are going to sit because I need to explain
one more thing if this is the magnet this is my next magnet this is north this is South magnetic
flux is being pushed on this side pulled on this one and pushed on this side so you wind up having
three magnets operating your coil if you got too many magnets and they're closed like this guess
what it's not going around the coil not good and a lot of your magnetism is swapping for magnet to
magnet instead of cross to the other magnet so having spaced out we're using 12 magnets or 12
magnet position 24 magnets see as the dual axial flux rotor okay one more thing I didn't explain
here trace the shape at the inside of your coil now I have the shape at the inside of my coil
winder dead center we will drill there's the half inch piece and I'll Center this up glue it on here
and basically from there out all I have to do is take it to the belt sander and sand off what
I don't need and there's my coil winder inside or shall I say if my coil winder is formed and
then we'll assemble the rest of the coil winder what I've done here is I've colored these just
for a few demonstration purposes and one bit of theory that I think would be very interesting to
you and I think most people really ought to know especially if you're going to design all there's
the reason why I'm showing you everything - I'm showing you because I don't want anybody to say
oh I have to get this certain brand of this or that like I said I don't know what disc I have
I just have measurements of it okay so doing all this stuff and showing you how I designed
and found the size of my coil and all that and how many windings for which size and what size
prop gives you something to go by if you want or you can use other programs on the web if this is
the north magnet north north north north worth which I have colored all orange and these ones I
did in blue I have found truly the way I did this paint stick put a hole in it in the center try
to get mine exactly Center so my magnets aren't perfect straight try this way works better there
we go put them like this you know the one in the three o'clock position over here is South if this
is north south north south this is south north south north and go all the way around you can
draw your magnets and finding your angles okay if this magnet is north and these to ourself
notice they're not real close over here they're out over here this is good design this means I'm
using this bag too this magnet and this magnet to power this coil magnetic flux is coming from these
and into this one and going around when the blue one gets here that it goes the opposite way in
any position in between that magnetic flux in the middle changes this is one of the points I wanted
to make this coil right here is not generating in this position you would think it would as soon as
the magnetic flux is at maximum and then when the blue ones here into orange ones you figures
generating again no that's not that's where your wave form comes down hits Center and then starts
generating the other direction winds up going to Center I'll explain it only generates when the
magnetic flux changes that's why you can't just leave a magnet and put this coil on top of it and
expect to get electricity out of it this magnet has to move and either needs to move farther away
move through it or it needs to move sideways which ever anything that will change the magnetic the
amount of magnetic flux that's going through in through the coil or the direction of the magnetic
clocks so as the magnetic flux is going through here coming from here and going in here and this
moves over here now we have a decrease in magnetic flux in here and this coil is generating probably
in the negative direction and then it gets to the top of its wave here and now it starts to
go the other direction since this magnetic flux right here is stronger then the wag magnet that's
over in this position so the waves going down when this blue magnet finally gets here that means it's
made it to Center again and as that magnet past it starts on its journey again makes your wave let's
go back to the layman's theory of its generating a peak here we have north north north these coils
right here these angles right here represent the parameters for the coils these three coils right
here here and here will be connected there will be a start here and it will wind around and come
over here Rhind around this one and dash around here wind around here and the electron finally
leaves out this way so you have a start over here and to finish all the coils on this are wound in
the same direction this one this one and this one are connected this coil this coil and this
coil are connected this coil this coil and this coil connected for three full phases three sets
of three coil twelve magnets for every three coils you need four magnets or four magnet positions and
that's the rule for a three-phase alternator I've got this explained notice over here this is the
coil this one's leaving this coil right here is generating because this magnet is leaving hello
I'm Scott Brown with green wind and other home energies one more thing I want to add before I
leave this video I always promise to show you as many shortcuts as I possibly can this one's pretty
cool if you look up here you notice this North magnet is on the line this North magnet is dead
center between the lines but it is a hundred eighty degrees over look over here this one's
between but this one's on this one's between but one's off in other words when I go like this that
should line me right up for the opposite side and the same thing for that one because of this
one and this one over here so all I got to do is find this line this line and this line and I get
the other ones these other ones are dead center between saves you from having to pull out your
protractor and figure new angles and draw a whole bunch of lines this sure does work a lot nicer
all your lines are already there that you that you're going to need and anyway that made that
a lot easier and one other thing down here after drawing the shape of my coil put a piece of paper
down there trim off what you don't need then you put it on a piece of wood here glue it down you
can scroll saw it jigsaw it sawzall it I wouldn't suggest a table saw or a skill saw but I imagine
it could be done not with much safety though uh what I plan to do is glue this down stick
a screwdriver through the hole in the middle and hang on to it I'm gonna take my belt sander with
80 grit sandpaper and I'm going to sand that bad boy down and keep it level to sand it down till it
gets to the paper and now I'll be done this beat that's the center of our coil winding thank you
very much I'm Scott Brown with Greenland and other home energies many good things to you and yours
you
