Stepping Down a Wimshurst

[wojwrobel]

one more thing if we want to increase capacity we can change dielectric material to let say mica its 5,4 from plexi 3,4 gain of 60% of capacity!!!

hello

ok i recalculated everting and i made a mistake

2mm is not 0.0002 but 0.002 so then our C=0.01221852 uf 0.000000 01221852 F

so its 0.000610926 C
at 1rps =0.000610926 x 8= 0.004887408 A = 244W
at 1200rpm=20rps= 4880W cycle 1
                           
but this mistake makes me thinking if we can use some special film as isolator that have good dielectric constant and strenght it will make big difference in output!!!

@Steven: True, I forgot that with the "thick syrup" maybe causing a stronger influencing and therefore probably causing a stronger induction effect in the pickup coil. This definitely needs a second look I guess.
@wojwrobel: hmm... I am eager to know how it will work out, since I can see you are actually building the device. It is still quite possible I have overseen something in my own experiments, also my construction was not the same as yours. It motivates to start experimenting again if one sees that other lay their hands upon it as well 

On a sidenote: beware... the most difficult thing I experienced during constructing devices like that is getting the discs not to wobble

Hi wojwrobel,
What, you're not satisfied with 4880W or even 244W? 
I'd suggest you try a small version first with what you have readily available, unless you're already experienced at this making these sorts of things.

Actually, what I was trying to get at was that his motor is probably going to do a heck of a lot of work just to turn the disks. But I'm not certain of that. I'm extrapolating from what happens with my Wimshurst machine, which is a bit of a different beast.

Agreed - groan. Another reason for starting small if you're not experienced at making these things. 1 meter disks can be expensive if you end up having to make a few versions before you get it right.
