you stated that your motor speeded up when you shorted out the HV coil, can you please tell me what happens if you place a normal 120v 60w filament lightbulb across the coil as a load instead of creating a dead short? dose it still speed up?

The 100 watt bulb is 9.9 ohms. Tried it and no light, no acceleration, no deceleration. The coil volts was 96 and .45 MA at around 716 rpm. So current is too low for an incandescent.

@Thane,

2) YOU DID NOT NOTICE A SPIKE IN MOTOR CURRENT WHEN YOU LOADED YOUR COILS - SUGGESTING INCREASED STATOR CURRENT - CAUSING ACCELERATION?

Didn't observe any spike.

I also removed the grinding wheel on the left and it would not accelerate at 716 rpms at 92 watts when shorted. Went to 1000 rpms and still could not get it to accelerate. Put the wheel back on and it worked at 716 rpms at 107 watts as before. Apparently need more slip to work at that rpm on this single coil unit with a higher horsepower motor.

Regards,
Larry

I DON'T THINK IT IS A QUESTION OF SLIP I THINK IT'S MOTOR INPUT POWER IN CONJUNCTION WITH YOUR SINGLE COIL.

IS THERE ANY WAY YOU CAN SET THE MOTOR INPUT POWER TO 107 WATTS - NO GRINDER WHEEL? OR IS THIS TOO FAST? I THINK THIS IS YOUR MINIMUM CRITICAL POWER INPUT?

THANKS

Guys,

"Angular momentum."

Calculate the difference in angular momentum with -- and without -- the grinder wheel.       

I know it make NO SENSE, in terms of "electrical engineering." 

But, as I have tried to point out before (gently ...), this is NOT about "electrical engineering" ... as Laithwaite (one of the master electrical engineers of all time) would CERTAINLY by now agree, in seeing these various permutations of Thane's original set-up  ....

You've stumbled over something FAR MORE interesting ... and ultimately "useful."

Quote@Thane: Your recent results were very interesting!  If confirmed, they seem to put to rest the theory that the device's effect is primarily created by core/coil induced drag that the subsequent loading somehow attenuates

.

YES, IT IS VERY IMPORTANT TO PUT TO REST THE HYSTERESIS BRAKE THEORY.

EQUALLY IMPORTANT IS TO ANSWER WHETHER OR NOT THE MOTOR IS SOMEHOW CAUSING ACCELERATION - WHICH WOULD BE TRUE IF COIL LOADING OCCURRED PRIOR TO THE MOTOR'S PULL OUT POINT ON THE TORQUE CURVE - WE ARE NOW ABLE TO VIRTUALLY STALL THE MOTOR WITH THE HIGH CURRENT COILS - THEN LEAVE THEM "ON" AND CAUSE THE SYSTEM TO ACCELERATE AGAIN BY ENGAGING THE HIGH VOLTAGE COILS.

ALSO WE NEED TO ESTABLISH REAL USE-ABLE OUTPUT POWER.
PERHAPS THE ESTEEMED DR. PETER LINDEMANN DSc. MIGHT BE WILLING TO REVISIT HIS CRITIQUE ON PESWIKI.COM - OR EVEN ENLIGHTEN US HERE?http://peswiki.com/index.php/Talk:Directory:Perepiteia_Generator_by_Potential_Difference_Inc#No_Useful_Output

AND FINALLY THAT THE EFFECT STILL WORKS WITH LAMINATED CORES - SOME SUGGESTED IT WOULD NOT EARLY ON IN THIS THREAD.

QuoteDo we know how much more power is required to run the motor with the rotor vs without, or is that an oversimplified and/or wrong-headed focus?

PB PUT YOU UP TO THAT QUESTION DIDN'T IT?

IT IS ONE THING TO GET THE COGGING TORQUE (HYSTERESIS, EDDY CURRENT LOSS) QUESTIONS ANSWERED BUT ALL GENERATORS NEED A ROTOR. THE INTERESTING THING IS IT TAKE LESS ENERGY TO ACCELERATE THE SYSTEM WITH THE HV COILS LOADED THAN UNDER NO LOAD CONDITIONS.

QuoteAlso, could you give a brief description of how this technology will be tested in the dune buggy for the non-technical among us? I'm trying (and failing) to figure out how this will all work with acceleration, braking etc.  Will the generator be shorted, or will you be able to draw useful current from that to charge the battery or perform some other useful tasks? If so, would that current have to be conditioned somehow to match the 'needs' of the battery etc. 

WE HAVE HIGH CURRENT COILS FOR REGENERATIVE BRAKING.

WE HAVE HIGH VOLTAGE COILS FOR REGENERATIVE ACCELERATION - STEPPED DOWN AND FED INTO THE BATTERY.

WE HAVE HIGH CURRENT COILS IN CONCERT WITH HIGH VOLTAGE COILS FOR REGENERATIVE COASTING - WHERE WE GET MAXIMUM GENERATOR OUTPUT TO OUR BATTERY - AND THE HC DECELERATION IS CANCELLED BY THE HV ACCELERATION.

WE HAVE A COLOSSAL DC MOTOR WHICH WILL ALSO BE EMPLOYED AS A REGENERATIVE BRAKE.

AND I AM CURRENTLY WORKING ON TESTING THE TOROID GENERATOR IN A SCALED UP VERSION - WHICH SHOULD GIVE US ANOTHER OPTION OF CONTINUAL BATTERY REGENERATION - WITH NO CONSEQUENCES.
