I am designing a three phase permenent magnet generator , and have a question.
as a magnet pair passes over a coil , inducing a voltage, that voltage is most dependent on ?
1) the angular velocity ( thats a given)
2) the pole strength
3) flux density
4) energy product.
5) thickness of...
last night i tried to get hydrogen from water using the aparatus shown.
i have to improve my collection tecnique but i was able to collect about a third of a cup ful ..
say i collect it from the top of a dome shape device .
my question is how will i mix it with the oxygen , to burn it
Ultra caps have come to Digikey ...YAY..
you can now buy a 110 Farad capacitor with a working voltage of 2.5V for $31.20 in quantities of one..
for more info google ' UltraCapacitor ' or the newest ' nanogate ultracapacitor.'
or check out whats happening at Maxwell technologies...

i am looking for an equation (integral) , so that i can predict what width to make a coil of wire , of certain length ,and thickness, so that it comes out to an outer diameter of 1.5" with an inner diameter of .5"..
i usually spend my time in the engineering section , but i thought that i would...
Our moon does not turn ??
Not at all ??
One would think that after a milenia of being bombarded by comet debris and asteroids that they would have nudged it a little..?
couldnt we spin it ourselves .?
I for one am tired of looking at the same view of the moon ,every full moon same...
Hi all ,
This FFT program may help some of you in your Engineering studies , it was a lot of fun to write and use ..
I wrote it in pascal .
All the instructions are included at the beginning..
I think my approach to reordering the twiddle factors is innovative as it is written in assembly...
anyone know of a magnetic analysis program ?
i'm trying to find out how much more power i can get out of my homebuilt generator if i add laminated steel around the perimeter behind the armatures..
today i got 70 V p-p no load ..and was able to light a 1157 automobile taillight with approx...
