Jimboot:

Let me just point out a few facts, not trying to give you a hard time:

If you measure the power consumption of your motor and compare that to the recharging power, just from looking at your clip it looks like the recharging power is only a small fraction of the power consumption of the motor.

It's not at all unusual to see the battery terminal voltage increase as the battery powers a load.  This has also been observed many times.

A closely related point is that often you see someone say "My battery only lost 0.12 volts after running my motor for 12 hours so 12 hours of running the motor only "consumed" 0.12 volts."  I think that you may have said something like that in one of your recent clips.

The whole concept of saying that a load "consumed" a fraction of a volt from the battery over time is really stretching it and is not scientific at all.  If you made an accurate measurement of the power consumption and the recharging power, then you would know the net power consumption of your motor.  The net power consumption of your motor times the run time will give you the energy consumption.  Then you can say something like, "I noticed that my battery voltage under load dropped 0.12 volts after it expended 2500 Joules of energy over 12 hours.  Do exactly the same test on another day with a different battery of the same type and size, or with the same battery with a different initial state of charge, and your observed voltage change may be different.  Just the ambient temperature in the room may affect the voltage drop.  By the same token if the ambient room temperature at the start of the test is different at the end of the test that also could affect the observed voltage drop.

I know that everybody does it, but the plain fact is that seeing the battery voltage slowly increase while the battery is powering a load does not mean that the battery is recharging.  You can see the battery expending energy and powering a load and you can often make a very accurate power consumption measurement with your multimeter.  Those facts override any observed increases in battery voltage and are clearly and unambiguously telling you that the battery is discharging.

Nup never said it. Made that mistake years ago My goal is to get the battery to charge up significantly then run it on caps. So what I am on now is better cores, maybe bigger mags and coils and possibly smaller gauge wire. The only claims I am making are based on what I am observing. Some ways to go yet but for me, this is way better than anything Orbo promised

My gen goil is 80ohm .05mm wire. Weighs about 2kg.

Hey Jim

Yea, my coil is about 51ohm and about 1000ft of 26awg.

So my magnets, rpm, insulated iron wire core, need a reality check to get the speedup. I had them at one point. Ive just been working on this lockup setup, while I have it working.

But it would be interesting to see the rpm/input differences, if any, between no coil present and a shorted coil.  Also what MH said, trying 1/4 ohm loads, 1/2, 1ohm, and a chart of the power dissipated.

I tell ya Jim, that motor, with the offset from the bearing is impressive. Now, if you had another drive coil on top, you might get the same or better running results, with the coils in series. This will save on the input.  ;]  Still use the bias mag, just add the coil. I see how the coil pushes on one side of the mag and pulls on the other, so there is not soo much tension on the shaft, and more just in rotation.

Also, have you tried the 2 bifi coils in parallel to drive the motor?  Put your helmet on. ;]

Thanks mate. I call it that as he is the only one I've seen demonstrate this. For me it is significant because ATM I have a motor in my shed that is running at 25k rpm that is charging its own run batter.very slowly charging but voltage is increasing. Not saying that there aren't a lot of variable to consider but I think it's something worthy of investigation.

Thane's effect is caused by a phase modulation of the CMMF through making a high impedance coil behave like a capacitor at high frequency.  This parasitic capacitance is generally engineered out of circuits, but in this case, the circuit depends on it.  As the coil tries to overcome its internal resistance to allow current to flow, the "induced" energy is stored electrostatically on the surface of the wire for a brief instant... long enough for the rotor pole that induced it to pass out of the way.  When this decays into current flowing out of the coil, the CMMF that is created sucks the next rotor pole in, as opposed to cogging the inducing pole.  Pump up the volume by increasing the drive voltage... this will increase frequency of operation, and should make the effect more pronounced.

ENJOY!

I achieved that r.p.m with my Spiral Torque coil and precision ceramic bearings.  My loop back to source charge was ticking micro volts up by the second. My Lenz delay effect was increased noticably by the use of  1' x 1/2" diametric neo tube magnets coupled end to end as output coil core. The bifilar coil on a radio shack magnet wire spool. The output coil a.c. pole shift is inhibited by the blocking action of the powerfull neo magnet field. The coil then acts as a Leon Dragone magnet generator, as well as a Lenz delay output coil. This can be accomplished with a  very low impedance bifilar coil a fraction of the size of your your Moby two kilo high impedance version.

Thanks Mags,
Actually I'm trying to work out how to short the gen coil. I learned from you years ago how to do it on the Ossie with a reed but unfortunately they melt at these voltages. Think I may need another hall circuit to short it out. There's probably a couple of ways I can get the speed up but I don't think I should Ive had it run as fast as 34k rpm. With no plexiglass and  hotglue holding it together I think I'll stay sub 30K lol. There is the opposite end of the axle where I am testing another mag and another gen coil as well but I really want to dry shorting the gen to see what happens.
