Great coil design. My son and I have been having fun with magnets and

Could you tell me why you have two coils of wire ? I thought it was one
wire coiled 100 times. OR is it just to make faster ? so you only have to
wind 50 times ?

Markozmajar- Google 'induction motor generator', and search YouTube, as
well. It appears that by changing a couple capacitors, a common induction
motor can be used as generator to produce 120 volt AC power at 60 hertz. I
haven't researched these much, but I would assume a 220 volt motor will
generate at around 220 volts. Might be an alternative to designing and
building your own alternator from scratch.

how many watts is this stator design?

Author carmatic (3 years)
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?

Author Michael (1 year)
how do you calculate wire gauge, dimensions, number of turns, number of
wires, blade length/swept area required etc. I want to build a turbine that
will produce 2000 watts at 12mph winds. I'd like that production to be only
60-80% of its maximum capacity. thank you in advance for any advice you may

Great vid. Thanks.

I'm sure he was. The edges of that piece looked sharp, though, just saying.
Also, the narrator said nothing about flux and there was no container of
flux on the bench. If you are referring to the flux dripping off the ends
of the wires, that happens when you use flux core solder, which is not the
same thing as using flux.

Nice generator. What is the efficiency of your generator/altenator? Is it
possible with any device to convert output current to 220 V, without
battery. I am thinking to use generator in hydro aplication where is near
constant power and RPM.
