Perhaps somebody should?

Put simply, IMHO, the acceleration effect is the result of negating oppositional forces associated with the generator core/current, and not the addition of extra energy into the system. This negation occurs due to a phase shift in the coil current and core counter-mmf, as a result of increasing frequency and /or higher than nominal output loads up to and including a short circuit.

IF THIS WERE TRUE HOW WOULD THIS EXPLAIN THE SOUND OF THE HV COILS' MAGNETIC FLUX HITTING THE ROTOR WHEN ENGAGED - SIMILAR TO A SMALL HAMMER HITTING THE ROTOR?

AND BTW - WITH A PURELY RESISTIVE LOAD ON THE COILS THE VOLTAGE AND CURRENT ARE IN PHASE PF = 1.

Would a magnetic field sensor hooked to the OS and placed on the back side of a core that has no backplate help prove the effect?

@Thane,
Thanks for the how-to list, but it is fast getting lost in the Thane-Ron post wars.

@Ron,
Thanks for the PC OS info. Why not send Thane some close up pictures of your E core setup along with the specs? Maybe this issue can be worked out.

Hi i_ron,

I really like it that way. Now one thing with your lathe-setup :

Can you please do two changes and place the results here :

1) put a 1KiloOhm, then a 100 ohm and then a 10 ohm load on your coil as I assume that your coil is just free running.
2) place another two magnets 20 Degrees left and right of your primary magnet, so you can simulate the situation of the interaction of the +di/dt ( accessing magnet ) and -di/dt ( receeding magnet ) with your primary magnet at TDC.
3) do  this with thh different loads according to 1)

This could bring us all a big step forward to really understand what is going on.

of course the coil should be the kind of a HV-coil.

Best Regards

FROM HOPTOADS SITE: http://www.totallyamped.net/adams/

When R1/Globe1 was turned on, the motor slowed a little bit, When R2/Globe2 was turned on the motor may have slowed a little bit again, but not as much when R1/G1 was turned on. But when you turned R3/Globe3 on, there appeared to be no change in motor speed at all. You continue and find that when you turned R4/G4 the motor seemed to speed up again. Same with 5 and 6. It's almost at the speed when you started. Then to your greatest surprise, you turn the short circuit on, and the motor goes to full speed as if there were no load at all.

FROM HYPERPHYSICS: http://hyperphysics.phy-astr.gsu.edu/Hbase/solids/ferro.html#c5

When ferromagnetic materials are used in applications like an iron-core solenoid, the relative permeability gives you an idea of the kind of multiplication of the applied magnetic field that can be achieved by having the ferromagnetic core present. So for an ordinary iron core you might expect a magnification of about 200 compared to the magnetic field produced by the solenoid current with just an air core. This statement has exceptions and limits, since you do reach a saturation magnetization of the iron core quickly, as illustrated in the discussion of hysteresis.

I_RON AND HOPTOAD WILL BE HAPPY TO KNOW THIS IS MY LAST POST HERE!

HOPTOAD AND STEVE EXPERIENCED THE SAME PHENOMENON - ONLY STEVE WAS SMART ENOUGH TO CHANGE HIS SOLID IRON CORES TO LAMINATIONS AND THEN WATCHED THE
"ACCELERATION" DISAPPEAR.

HOPTOAD USED HOLLOWED OUT IRON CORES WHICH EVENTUALLY SATURATED WITH LOAD.

SATURATED CORES REDUCE EDDY CURRENT LOSSES AND EASES MOTOR WORKLOAD BUT AS STEVE DISCOVERED IT IS NOT SUSTAINABLE.

So now I guess the Subject name will need to be changed to the I_Ron and Hoptoad Perepiteia Replications thread. This will be a tough sell as neither thinks it works.
