DIY 1.5kW Wind turbine [Part 1] – Magnet rotors

hey whats up guys you know I always hated the wind but I was always interested in
renewable energy so i figured if i manage to build a wind turbine and
reduce my electricity bill
I will for sure start to like windy days
so my goal here is to build a wind turbine which is capable of producing
one point five kilowatts of energy
it actually might produce more but let's go with 1.5 kilowatts which would
be very good already
this is not going to be an how to video as i'm learning myself how to build one
of these as I go
so just keep an eye on my channel and I will keep you updated on the progress
if everything goes fine i will build some kind of controller that monitors
the current wind speed RPM of the wind turbine, current power being produced
volts and amps and all this information will be uploaded to some kind of IoT
service so I can get detailed graphs I will also implement a brake system that
shorts the outputs of the wind turbine in case the RPMs get too high but
enough of talking
let's start ok so just a very fast and basic explanation on how the wind turbine
will work it will consist of a stator with 9 coils each with 70 turns of
14 gauge or 1.6mm enameled copper wire and this stator will
be sandwiched in between two steel discs containing 12 neodynium magnets each as the
discs turn AC electricity will be produced which then needs to be rectified
to get usable DC current which can be used for example to charge batteries or can be
injected to the grid using a grid-tie inverter today I'm starting with the discs
ok so the discs i'm using are 30cm in diameter so about 12"
and are 6mm thick or about a quarter inch a lot of people use
brake discs for this which is fine if you can get them free
but I got mine laser cut with the right dimensions for 6€ each for about
6.70 US dollars
and for such a low price i don't think it is worth to use break discs
I used sandpaper to get rid of rust and to roughen the surface so the magnets stick
better then I used paint thiner to clean it
please don't mind the shaky video this was recorded using a security camera and it
was a little windy
I bet as soon as I finish the wind turbine and I'm ready to test it
the wind will completely vanish for at least a week
that's how lucky I am
I designed and 3d printed these templates for the magnets
but I could have done this manually with wood
to glue the magnets i'm using a drop of super glue
this is just temporary since later in this video I will pour polyester resin
on top of the magnets and the disc
as you know the magnets have two polarities the way you have to glue them
to the disc is if the last magnet has the north side facing up
you have to glue the next magnet with the south side facing up or vice versa
as you can see i'm testing here so the face that repels to the last magnet is
to one that is going to stick to the disc
and in the end you should always test if all the magnets are in the
correct position as you can always knock them off as you can see I'm using a trowel
to get it off because it wasn't quite in the right position
I recommend using gloves to do this
because you know these are quite strong and if you get a finger
between two of these
it's quite painful trust me
these magnets are N52 grade and are 1" x 2" x 1/2"
or 50mm x 25mm x 10mm
so to contain the polyester resin i'm using this foil tape since it's quite wide
I'm cutting it in half so i can use it for both discs
same thing inside
you can use any other type of tape as long as it glues quite good to the disc
and it doesn't leak
make sure you are working on a leveled surface
i'm just using normal polyester resin which is also known as fiberglass resin
and you can get this in any home improvement store
I used about 200mL for the two discs
Oh I don't recommend using a can
to do this because it gets attracted to the magnets
I didn't think about it so you can use like a…
the bottom of a bottle for instance
you want to fill the spaces
between the magnets but not up to the surface of the magnets
you want the magnets to stick out a little bit but still you want to cover the magnets
with a thin layer
unfortunately i don't have a picture of the finished discs but i will show you
in the next video
that's it for today if you enjoyed this video please subscribe and thumbs up and
please comment i never received a comment on this channel which i don't
know if something's not right with my youtube channel or people just don't comment
so go ahead and leave a comment
Have fun!
