Depalma N-Machine high voltage ???

[alvarohn]

Is possible to make a N-Machine without mechanical commutator???

If the Voltage output is very big the electricity could jump the air, with a spark gap or something…

Does anyone knows the math for the output voltage? Diameter + speed + magnetic strength???

I was looking all places for the math in the N-Machine but could not find it.
What you think about it?

Best,

Alvaro

There are two designs - the first involves a bath of molten sodium for the disc to run in - mercury might do - (which is not strictly what you have in mind) and a second involving two discs rubbing against eachother, with the power coming out on the two shafts.

If i recall correctly, the voltage tends to be small and the current high.

The output of homopolar generators are high current\low voltage. If interested in this type of device, you should look at the old boderlands build whose output was ac as that would probably be easier to extract without brushes. Although, I don't think that they ever did find a more efficient way to do it.

tnx for the replies.

it is always the same deal,... big money and time...

my idea would be intresting in a bigscale maybe

since you are right that depalma is low voltage high current machine.
