Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

LH is probably Liquid Hidrogen , it could be Helium too but Hidrogen needs about 20 Kelvin "only" (while Helium needs to be cooled to about 4 Kelvin)  to become liquid.
LN is Liquid Nitrogen.

Thanks Gyula, I now understand

LH is probably Liquid Hydrogen , it could be Helium too but Hydrogen

It is the former. Expensive stuff and volatile

Thanks Gyula,

so i have to build myself a 38mH coil which instead of 10 Ohm has a much lower resistance, like 1 Ohm.

Any suggestions on how or what type of coil that might be (which core)?

Hi Itsu

Not an easy result to achieve!... unless coil size and copper mass does not matter?

try the attached coil calculator program.
Results are air core.
I've used it for years, with accurate results.

Let me know if you have any questions.

Hi everyone,

as promised, here is a test of verpies circuit which I've connected to my pulse motor to which I made a new drive coil for on Metglas core.
I also did a true motor efficient (electrical to mechanical) load test using a generator coil as load on the pulse motors magnet rotor.
@ MileHigh, finally a pulse motor that can do more the just turn a rotor!
The results are quite good I would say.
