Good advice Clox, in the same vein of thinking, this is a handy project to aid in device analysis :

All you guys working with results expressed in RPMs.
Do you ever test what the actual no-load friction of your device is at a range of RPMs? This should give direct insight into the overall efficiency of your motor. I suppose you'd remove the coils, spin the rotor with an outside motor, and measure in way way, as precisely as possible. Bearing and air drag are likely to be the only things slowing the rotor down when at constant RPM?
Measuring kinetic energy at one RPM and wind downs (plots multiple times per rotation) from top speed down to low speed, might allow to calculate drag coefficient very precisely. Then a simple program could always take input watts, RPM and known drag constant at every specific RPM, to come to an efficient percentage.
I know, this might be a project all in itself, but seeing these figures might really offer insight you seek. Bet when you do this more often, getting the data in on your latest rotor setup will be a matter of minutes.
Efforts to get the rotor at the lowest possible drag may also be saved, as the rotor itself will be added to the external load in calculations. As long as it performs consistently, not too much afffected by heat or moisture in the air. THANKS for showing the great work you do.

Hi Rod, wonderful work
I'm thinking of ways you could lower the input power and still get the same RPM.
My setup runs on less than 1 watt and achieves ~2000 RPM. Next week (when new parts arrive !) i'm hoping to get a lot more out of it with a different bearing shaft assembly.
I use 800 turns of 0.25mm wire on my 4 drive coils, resistance ~40 Ohms.
Hope this helps

I had an alternative theory on this effect but it looks like i was wrong. I thought there was a delay in the magnetization/demagnetization of the core so that over a certain RPM, lenz was still present but not top dead center but rather after TDC. As the magnet approaches a gen coil under load, lenz tries to repel it and after TDC lenz attracts it. If it is offset due to delay in the core, the repulsion on lead out will push and the attraction will also push virtual south.

Michael points in the right direction.
According to theory, at a high enough RPM, there is an additional
rotating field establishing that leads the magnet's rotation.
And it is this field that skews the PF to your favour.
Probably that's the reason why not many people see this effect, because
they would not come to the idea to overspeed the rotor.
If you have the right bearings, a proper construction and manage the coil positioning, then there is no
problem with such a speed.Last edited by Xenomorph; 08-01-2011, 06:56 PM.

Seems like high RPM is critical to achieve lenzless. However, 4k+ RPM is too high of a safety risk for an average rotor, and the centrifugal component increase exponentially with RPM.
If we can achieve lenzless with less RPM using passive components.

Frequency
It is all frequency related, Timing, RPM, all related to impulse frequency. Just need to think a little out of the wood so you can see the trees, it is all to do with a third field which does not appear until you get into a higher frequency.Originally posted by toranarod View PostThanks Matt. I will give it a Try. its all about the correct RPM.
I will probably need to build another coil slide like the first coil sits on.
I may in a few days post something that will explain this event.

Magnets
I have spent the day changing magnets and coils. documenting what goes with what and what provides the best results.
I got to say there is a specific combination of events that provide the best results some setups do not work at all. I Just cannot ascertain why. I can speculate and hypothesis but i need fact if this is going to be exploited to its full potential. I don't have the equipment to analyse the magnetic field at the point of collision.
I got a record RPM today of 4560 RPM. Also had another magnet crash inserting a coil. had things running again an hour later.
The second coil provided the same amount of power as the first. Both generator coils could provide equal amounts of power at 4000 RPM. as listed in the table in the last post.
The problem is its to hard to bolt a coil in place at 4000 RPM. and it will not get up to speed if the coil is already there.

I haven't read his stuff, but I'll go look it up.Originally posted by Xenomorph View Post@Mathew:
This is a nice experimental verification of what Harold Aspden talks about.
Bringing iron mass into saturation and harvesting zero point energy
when it desaturates.
(The whole point behind Romero's Biasing magnets...)
Keep it up!
I have seen devices all along in which this already happening on some level. The energy is reverse time without a doubt and grow on an immense scale. When dumped into a capacitor the time is corrected and it becomes alot of power.
I am not sure about the biasing magnets. Unless they are used to cause a "Magnetic Neutralization effect" they most likely aren't doing much. But I have not messed with it so I'll let ya'll make that decision.
Best of luck, I gotta get on the road.

this OU stuff can get very lonely. Its great to get a bit of support.Originally posted by ashtweth View PostRod , very nice work, we made the Doc's caloric meter for you and can send down for a heat measurement in a few weeks when finished if you need it, i think an analog DC in and heat measurement out would top it off.

your the man

That is quite great! you are overunity already if you use two such coils. What is your load? Of course not considering the eddy drag you might have.
I have finished making my new coil, about 200 turns of 2mm wire.
Tests to be done tomorrow. More turns to be added.
