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

Luc, 

i like the last one best, thats what i use i think, but you probably use a different tab on the "openchoice desktop" application.
I use the green tab, see below screenshot,  i guess you are using the red circled tab.

Meanwhile i have redone my measurements as to see if the overunity cap recovery condition still exists.

It sure does.

Going by the zoomed scopeshot:
Input energy during the ON-pulse:  E₁ = 4.070W * 4.36ms = 4.07 * 0.00436 = 0.0177452J = 17.7452mJ
Recovered energy in C2:  E₂ = ½ * 10μF * (99V)² = ½ * 0.000010 * 9801 = 0.049005J = 49.005mJ

E₂ / E₁ = 49.005mJ / 17.7452mJ = 2.76159 = ~276%

These welding rods is good stuff !


P.S.
The sawtooth current energy estimate yields:  E₁ = 660mA * 12.4V *4.36ms * ½ = 0.660 * 12.4 * 0.00436 * ½ = 0.017841J = 17.841mJ  ( pretty close ! )

Isnt it amazing what can be found when one has an open mind when it comes to these laws of physics. As i stated before Verpies,it would only be you of the EE guys that would take note of what others have to show when it go's against these known laws--oh and the books lol.

No bad Itsu--not to bad at all

Itsu

The one you use "green tab" give me the below. The red tab give me the next one with no data.

So by using the software I don't get anything better. It's the scopes limitation compared to yours which must be better.

WOW

Excellent results there Itsu!!!... congratulations

Thanks for your great tests and sharing
