And if I was still here for any reason such as having quite literally freezing cold feet ...

Can't you slip on a nice pair of warm sheep?

That's a mental image I didn't need.

Although I wouldn't need to walk anywhere, I could just put reigns on them.

K, I lied to you, with the HV coils open, and the HC coils into a 5 ohm load (2 volts at .36 amps) the PM (prime mover) uses 330 watts.

SO 0.8 WATTS FROM 330 WATTS - RIGHT?
YOUR RATIO IS 0.0024

With the HV coils shorted in series, the output on the HC load drops to 1.47 volts at .27 amps and the rpm goes up and the PM draw drops to 270 watts.

NOW 0.432 W FROM 270 WATTS
YOUR RATIO IS 0.0054

ALTHOUGH YOUR ENTIRE SYSTEM IS HORRIBLY INEFFICIENT IT SAYS NUMERICALLY THAT  THE RATIO IS APPROACHING A RATIO OF 1.0 (100% SYSTEM EFFICIENCY 1 W IN = 1 W OUT)

NOW IF YOU DID YOUR EFFICIENCY CALCULATIONS THE CORRECT WAY - BY MEASURING POWER IN THE DRIVE SHAFT PRIOR TO THE GENERATOR YOU WOULD GAUGE EFFICIENCY BY HOW MUCH YOUR SHAFT SPEED REDUCED (DUE TO GENERATOR HC COUNTER TORQUE) TO THE POWER COMING OUT.

AND YOU COULD TOTALLY BALANCE THIS WITH THE WORK ENERGY PRINCIPLE.

BUT THEN IN THE HV SCENARIO YOU WOULD HAVE TO THROW THE WORK ENERGY PRINCIPLE (AND THE LAW OF CONSERVATION OF ENERGY) OUT THE WINDOW BECAUSE YOU WOULD HAVE COMPLIMENTARY HV TORQUE IN YOUR DRIVESHAFT AND NO COUNTERTORQUE SPEED REDUCTION TO ACCOUNT FOR THAT OUTPUT POWER - AND EVERYONE WOULD TOTALLY FREAK OUT - ASSUMING THEY WERE NOT ALL STUNNED BY USING TOO MUCH IQ LOWERING FLUORIDE TOOTHPASTE.

PS - I AM MOUNTING MY HV COILS ON ONE SIDE OF THE ROTOR AND HC COILS ON THE OTHER TO KEEP THE OUTPUT AT A MAXIMUM AND AVOID THE FLUX BATTLE GOING ON INSIDE THE CORES.

BTW YOUR TESTS ARE VIRTUALLY IDENTICAL (REACTION WISE) TO OUR HIGH SPEED TESTS.
NICE JOB - WE ARE THINKINK ABOUT LET YOU WESTIES JOIN CANADA SOME DAY SO KEEP IT UP!

About time!

I added steel pieces to the transformer cores the same diameter as the Neos and aligned with them so that rather that being flush with the rim at best it could get beyond the rim.

I also had washers which I didn't measure but they were a magnetic steel and over 2mm thick, I placed them inside the cups for the magnets that needed boosting and taped them to the back of the cups for the ones that didn't.  (NNN SSS NNN SSS pattern)

The end result was magnet to stator gaps that varied from lightly touching to a 5mm gap.

So I fired it up, previously I had been running it through a transformer that pretty much halved the 240v and then put it through the power controller, but with this new tighter gap it was only going to work with the power controller run from the mains.

And so I fired it up and guess what, it works!

When I short the HV coil is speeds up, when i short the HC coil it slows down, when I short both depending on the speed it's at it either speeds up or slows down.

Needless to say I am very very happy!!!

I would love to run more tests but it's late and there is smoke coming out of the motor!

Luke, that money may have to wait a bit longer, my birthday present to myself looks like it's going to be a higher powered motor! (Oh, and I gave in and bought a real tachometer which makes life sooooo much easier than any of the jury rigged methods, totally worth it!)

So yes, may this be a lesson to any replicators, the flux really needs to get in there!
And if it doesn't all the turns in the world or even a closed flux path won't make up for too great a rotor/stator gap.

What is the highest wattage bench grinder anyone has got the effect with? Because if I am going to get one it needs to both put up with the punishment and show the effect, the current one looks to be on it's last legs.

Thane, what do you recommend?

I'm soooo happy right now!

But on to more serious matters, the state with the most fluoride in the US has the highest % of people with dentures, and the one with the least fluoride has the lowest %!
Fluoride is used as a rat poison.
And Hitler gave the Jews in the concentration camps fluoride.

So ya gotta know it's good for you, all the evidence shows it's bad for teeth.
But the interesting thing is that finally large numbers of officials and doctors are actually starting to rethink fluoride which is amazing!
