From what I saw this is an insanely important step, eh? 100 watts is promising, but is that the low speed output?

EVERYTHING REMAINS THE SAME - JUST SMALLER AIR GAP AND EMPLOYING REAL E CORES RATHER THAN STACKED I's.

5x jump from 20 watts I would think you would need to increase the RPM's and decrease the airgap.

With the 3 magnets configuration instead of the 1 magnet configuration how much gain is that going to provide?

ASK ME AGAIN AFTER WE DO IT!

Whats the limiting factor in coil o/p power? Heat?

THE COILS ONLY GET HOT IF YOU MAKE THEM WRONG - AND WHO CARES NOW THAT WE CAN IMMERSE THEM IN MINERAL OIL. 

I was doing some sums with some buds last night, and we figured we could fit 6 connected 12" diameter rotors in the space where the driveshaft used to be, I think we could just squeeze 8 coils in per side, so 8 x 2 x 6 = 96 coils,

96 coils at 100 watts = 9600 watts so almost 10Kw output. If input lowering remains true then who knows how low the input energy would need to be.

DON'T FORGET IF YOU INCREASE THE MAGNET STRENGTH YOU INCREASE THE OUTPUT - DOUBLING THE MAGNET STRENGTH DOUBLES THE OUTPUT.

And furthermore, using the power harvesting coils as non - continuous duty cycle may allow us to harvest huge amounts more. IE overrev the hell out of the motor, dump a massive coil melting amount of power into the wheels, accelerate up to speed then coast while the engine cools down, then 13 HP is more than enough to maintain 100KPH+ on flat ground, until you need to accel or climb a hill in which case you over rev the motor again and repeat the process.

OR ROTATE COILS IN AND OUT OF USAGE...

Also, if you get a free second do you think you could fire me off the dimensions of the coils and magnets you are using, I want to try some ideas in Sketch Up. Cheers

THIS WEEKEND I'LL DO IT.

YOU FORGOT TO TELL PEOPLE ABOUT THE FLUX HITTING THE ROTOR "THING"!

Ok, cool. I will definitely ask again, I'm dying to know.
If the coils don't get hot / mineral oil bath, than whats the limiting factor? Why would we not be able to get 500watts out of each coil? If we could do that it'd be freaking brilliant. Just up the RPM's of the whole system = more power. We could get 50 hp's out of the car motor design. WOOOOO

In regards to magnet, your already using N52 grade magnets, lol, I had thought N45 grade was the highest. How do you propose to double the strength of the strongest magnets I've ever seen?

Also in regards to magnets, what handling advice do you have for actually putting the magnets into the holes in the rotor so near eachother without losing any fingers?

And in terms of the clunk thing, omg peoples of this forum. Just wait till you hear it. When the HC coils get loaded down not only does the rotor NOT immediately speed plateau, it continues to accelerate albiet more slowly, AND theres a crazy noise. The whole thing goes THUNK as the coils start taking power right from the magnets without significant back EMF.


If you could measure the nice machine made coils that you are getting set up from the manufacturer, that would be the best. Once I get the dims I can figure out what size the rotors need to be.

Thanks Thane

Dear All,

Please find enclosed photo-data for the new E CORE orientation that I tested today.

Compared to the previous "I" - Modified - E Cores we have saved close to 100 input wattsand our chances for success have increased 100%.

This is due to reducing eddy current lossed in the core. I am sorry I didn't do this earlier - but better late than never. 

So now we should be at "system" over-unity with 4 HC coils producing only 26 watts/coil which I have already been able to produce - in fact I expect close to 50 or more watts/coil due to more efficient flux transfer.   

I will also be employing 4 of the High Torque HV coils as insurance.

Again, sorry for the delay.

Cheers
