The Ossie motor

[woopy]

Good morning all

still alive and no gun shot during the night

and the motor spins hapily

battery at 4.07 volts and supercap at 6.65 volts. I suppose it is not good for the 5.4 volts rated supercap so i stop the game and will order stronger magnets.

But any idea why this happens ?

You got lucky buddy....  Good thing you stopped the run, I was getting worried it was going to turn out really bad.  As far as why this happens, I think you are referring to the fact that the cap loaded up at a higher voltage than the run battery.  If this is what you are referring to, then you must realize that when the switch is opened and the magnetic field collapses, it collapses with a higher voltage but lower current.  Sort of a natural transformer if you will.  It is not uncommon for low run voltages to charge caps up over 50 volts using collapsing fields, sometimes WAY OVER 50 volts.  Just depends on the setup.  Your setup may be doing extremely well and could be very efficient, but please dont make the mistake of thinking because the capacitor charged to a higher voltage than the run battery that there must be more total energy coming out than what you are putting in.  Capacitors tend to be kind of lossy, and the actual energy in a capacitor is quite difficult to compare to the actual energy in a battery.  But using the proper equations, E=1/2C*V2, you can very accurately tell how much energy is in a capacitor.  A battery is just not that easy to measure, and a volt meter can lie to you when measuring them especially when a surface charge is present.   It's like comparing apples to oranges.  But sometimes that's just what we have to work with.  Keep your head up, and keep rolling forward!  Your bringing in some great data here for us all to kick around.

Your induced voltage is approx 10V AC. So your supercap would eventually charge to 10 volts if it wouldn't break before.
It's not good for supercap to overvoltage it because it will start to leak and lose it's ability to hold charge.

....
1 -with the single Hall sensor and circuitery    the Hall circuit consume from itself under a battery at  4,2 volts about 7 milliamp  and when i find the right Hall sensor position the ampmeter shows NOTHING more than the basic circuitery   difficults to say because the amperemeter flickers between 6.4 t0 7.6  but anyway very very low  ?  This shows that without the circuit consumpton  the motor could work with ALMOST NO  current ?  OUCH ?

Hi,

If you use the schematic shown in your post here
http://www.overunity.com/index.php?action=dlattach;topic=8731.0;attach=42071 then I think you could increase the 1 kOhm resistor up to even 4.7 kOhm in the collector of the 2N2222 to reduce the average 6-7mA current to 3-4mA or so  (the 1 kOhm if it really 1 kOhm,  directly shunts your battery whenever the 2N2222 is ON). 
Also you may wish to select some TL4905 for less current (their data sheet says their typical current draw is about 4mA and the max is around seven, manufacturing tolerances).

What are your coils DC resistances now, I cannot recall? (I know they are +-+-+-+- in series.)

Thanks for the cap data.

Hi Gyula
You may recall the circuit you suggested for the Sotropa Motor using a Hall IC. Rather than using power from the source to trigger the transistor, I isolated the Hall circuit and used a separate 2V battery. This eliminated the power consumption from the source.
