Hello,
I would like to point out that experiment presented in the Miroslav13 video here:
http://www.youtube.com/watch?v=bFXecIxEqR4is not conducted correctly and has sadly lead to incorrect assumptions.
1) measuring AC output using these instruments is erroneous. One of correct ways is presented here:
http://www.picotech.com/applications/mains-power-analysis.html2) Reference point for power measurements should be machine with no coil in place (physically).
3) It's good practice to provide full parameters for all components used (resistance, inductance of coils etc).
4) Fact of being granted a patent does not guarantee that the concept is viable because it takes very specific knowledge to sort this one out.
Seen "effect" is explained as follows:
The "regular" coil A tested seems to be winding made with thin wire and relatively small core. Core is made from conducting metal (laminations). Also it's a solenoid so magnetic loop is very "open". All this boils down to pretty poor performance with high ohmic and core loss and low inductance. Result is that even when shorted it behaves as resistive/dissipative load and naturally slows the generator down.
In case of the "special" coil B there are some differences:
Core is still made from conducting metal (laminations) but is much larger and forms better (more closed) magnetic loop. Also the wire is thicker. This results of relatively high inductance and low ohmic losses.
These differences have following consequences:
When coil A is "open" only effect it can have on rotor is due to core losses. Since core is small and coupling between rotor and core is also small effect is non-existent. But when coil B is "open" then coupling between rotor and core is good and core losses kick in very heavily.
Coil A => 12V * 0.69A = 8.28W
Coil B => 12V * 1.01A = 12.12W
---------------------------------------------------------------------------------------
3.84W of core losses B vs A
Now when coil A is "shorted" then wattage goes UP (or RPM down) due to mainly RESISTIVE nature of the coil.
When coil B is "shorted" then wattage goes DOWN (or RPM up) due to mainly INDUCTIVE nature of the coil.
But why is it so? Well there's a little "secret" that has surely fooled hundreds of researchers (including me)
This is the "secret" (drums beating):
When the generator coil is good inductor and has high Q on working frequency it will cancel out magnetic field inside the core when shorted! Effectively cancelling out all the core losses because there's no more changing magnetic field in the core. Core has been "shielded". When the core is high-loss core, shielding it speeds up the generator.
This is all that there is to "speedup under load" that various have reported and all that there will ever be.
This effect (speedup) is promiment only when having high-loss cores from laminations etc. It will go away when having low-loss ferrite cores etc.
When having low-loss core there will be no net load to prime mover when coil is "open" and no net load when coil is "shorted" also.
Also I must sadly point out that there is no extra energy to be taken from this or any other setup involving linear components and no source of extra energy. Maybe time to stop chasing ghosts... Concept of "classical OU" and "perpetuum mobile" is spoon fed to us by the PTB, scammers and people who have not done their homework.
I'm sure user verpies would wrap this information in more "teachable" form and support it with some formulae.
