DEAR ALL,

I AM IN THE PROCESS OF BUILDING A PAIR OF TOROID COILS AS PER THE YOUTUBE DEMO VIDEO # 4.

I DID A QUICK TEST AND WITH EACH COIL INDIVIDUALLY SHORTED THE SYSTEM DECELERATES.

INTERESTINGLY ENOUGH WHEN WIRED IN SERIES AND THEN SHORTED THE SYSTEM ACCELERATES.

IDEALLY THE BACK EMF INDUCED MAGNETIC FIELDS ARE NOT SUPPOSED TO ENTER THE AIR GAP AT ALL - THE LOADED COILS EFFECT ON THE PRIME MOVER SHOULD BE NIL.

Thane,

I love the way you use off the shelf parts for your experiments!

However a couple of points in this last test... 1) the copper shorting rings are still in place, how does this affect the test? 2) not nearly as much back iron present as in video #4, 3) the back iron that is present is sort of at the bottom of the "toroid", 4) the "toroid" has two air gaps of it's own....sorry, do it again, lol

Thane! Luc!  I saw Ironman last night at the movies, and I demand that you abandon all this nonsense and make me a big iron suit! Pink please.

Thanks in advance,
JM

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

Okay, Took the grinding wheel off, rewired to move the controls farther away and set up a neo shield.

At 107 watts and 1100 rpm, shorted and went to 105 watts and 1197 with coil volts at 117. Slow acceleration, tried other higher rpms and had even less rpm difference. Also, varied the air gap, but the original seemed to be the best.

One other difference that may be useful as RCH suggested. Without the grinding wheel the rpms returned to the original value after unshorting. With the grinding wheel the rpms would remain at or very close to the accelerated rpms after unshorting.
   

@RCH

Found a lot of interesting info on Eric Laithwaite, especially his reactionless propulsion patent. Is there any working units?

Regards,
Larry

YES THE GRINDING WHEEL ADDS TO THE UNSPRUNG WEIGHT OF YOUR "FLYWHEEL" AND MAKES IT EASIER FOR THE MOTOR TO MAINTAIN THE ACCELERATED SPEED.
