Thane,

Could you clarify the conclusions you drew from your two motor test? I didn't quite get that...are you moving away from the back-emf directly affecting the motor's magnetic fields theory?

Thanks,
JMe

ACTUALLY I WANTED TO LET PEOPLE DRAW THEIR OWN CONCLUSIONS I AM TRYING TO AVOID ANOTHER CRUCI-FICTION JUDGEMENT.

BUT I AM GOING TO HAVE TO GO WITH A YES ON THAT ONE. THAT MOTOR THAT IS 2 FEET AWAY FROM THE ROTOR ALLOWS ACCELERATION - HARD TO IMAGINE FLUX GOING THAT FAR?

IT WOULD APPEAR THAT BACK EMF ENTERING THE MOTOR MAY NOT BE IT AT ALL.
THERE IS HOWEVER CERTAINLY SOMETHING FUNKY ABOUT THOSE HIGH VOLTAGE TRANSFORMER COILS THOUGH - WHICH POSE A WHOLE NEW SET OF QUESTIONS AND POSSIBILITIES - IT IS NICE TO SEE REAL POWER AND ACCELERATION.

TOO BAD PB IS UP TO HIS/HER NECK IN SAUERKRAUT. HE-SHE WOULD HAVE A FIELD DAY HERE NOW.

Thanks a lot JustMe,

I was fat, dumb and happy until you brought that up. Originally, I didn't fully understand the double motor comment from Thane, too interested in those good looking MOT's. You motivated me to read it again and again until I understood. Now my brain is gone to ache all night long (Round and round and round we go, for sure) . Enjoy the beach.

Regards,
Larry

I agree wholeheartedly. My own (completely open magnetic system) experiments ruled that out. IMHO, Magnetic Phase Drift is the issue. The counter MMF changes it's oppositional phase relationship with the inducing MMF. Magnetic Phase Drift increases as the load (O/P current) increases to a point where the counter MMF cease to be oppositional.

The high voltage coils are obviously within the correct impedance range for the RPM and number of magnets (Frequency) available. Even the low impedance coils would eventually exhibit the same characteristics if you were using very high speed motor drivers, because, whilst the DC resistance of the coil remains steady, the impedance of the (any) coil increases with frequency. There appears to be a critical relationship between frequency, impedance and current within the coil, at which the effect kicks in.

The whole purpose of my own high speed experiments in 2001-2002 was to prove exactly that. That even low impedance coils will work, given the correct design parameters. Why bother with low impedance coils? If you want a constant voltage supply capable of delivering large volumes and variations in current, then low impedance is essential.

I was looking for a more efficient alternator design for replacement in motor vehicles, and aimed all my experiments at the 14 Volt high current region of generation.

Understanding the nature and curvature of this phenomenon has been one of my latent desires since I first studied it in 2001. Understanding the relationship is IMHO the key to building optimized highly efficient open system generators. Lacking any model building capabilities in my current location and circumstances, I have to be satisfied at the moment with watching the outcomes of yours and others experiments. To that end I wish you all good luck. I have always maintained, that this is a useful effect. I'm sure when you've studied it further you will arrive at the same conclusion.

Speaking from experience, I can only say YEP!  Success, of any kind, is always a nice feeling     ......... KneeDeep
