Has anyone seen Lasersabers new motor runs on 1000uf cap

You should be able to charge an external capacitor all the way up to the peak voltage of the spike, much higher than the supply battery voltage. As you have already figured out, the run cap can't charge up because it is always being shorted out during each cycle. But you can transfer energy from your run battery into an external capacitor very effectively, as you will find out. Then the "trick" will be to switch the external cap back into the circuit at the right time to put its collected energy back into the rotor's rotation. You could do this with a simple comparator circuit and a transistor, probably.
You will need a fast diode, the faster the better, and of course its voltage rating should be high enough to withstand the maximum spike voltage. Something like MUR1560, but the UF4005 - 4007 type rectifiers might be good enough. I've also found suitable fast diodes in old TV circuitboards. RG10A is a fairly common superfast rectifier diode in TVs. RU2 or RU2B are also in there.

Hi Conrad,

Sorry but the air core coils Ossie used have 1.05 Ohm DC resistance, 1.8 mH each. See this link: http://www.overunity.com/8731/the-ossie-motor/msg226572/#msg226572  and Naudin used also 1.8 mH inductances but with 0.55 Ohm DC resistance each: http://jnaudin.free.fr/ossiemotor/indexen.htm   This is one reason why they used series resistances: to limit input current and save reeds from premature burning. But the other reason for the series resistors is that a balance, a matching can be reached between the motor impedance and the battery impedance, this insures the best operation and long running time. On this AC/DC matching, here is what Ossie wrote:

I agree with trying to collect the spikes in a separate capacitor and see the voltage level received.  The up-transformer sounds also good to me and I also think the recovered energy strongly depends on the input energy, minus the losses. (unfortunately, the advantage of high impedance coils for motor mode turns to a disadvantage when capturing the spikes: the high impedance coils will operate as high inner impedance generators when supplying the spikes  so also matching would be needed towards the 'load' that uses up the captured energy (or use the captured energy at a time the motor cannot see that load).
Regarding the DadHav pnp-npn circuit, you sound to be aware of the fact that the rotor magnet should be given a good hand-pulse to start rotation, i.e. induce an intial AC voltage in the coil because otherwise the circuit cannot work. IT may well be transistor type dependent though. The circuit can be considered as an oscillator after the start, syncronized by the rotor magnet inductions.

Ordered 50,000 ft of 42awg wire. Well, 49,000 and change.  Will be here next week. $35 shipped ebay. 

Not a bad price and will have enough to do many things at many turns and many feet.

I said this once a long time ago back when Zeropoint132 made his no bearing bedini with 4000 turns bifi, I said, I wonder if it is the fact that the coil is wound with many many turns of fine wire. But I never messed with very fine wire because I didnt think I could get much out really, and I wasnt sure if Z's motor actually worked. But now I have enough of the right wires that I can give it a go. I tried it with much lesser windings and slightly larger wire than Z used, but didnt work. 

One thing I am thinking now is that maybe Z's motor wasnt self running really, maybe it was just like Lasersabers motor. Dunno.

Lasers motor seems to be 'running' on a fine line of balance between the coils driving the rotor from the cap and effective charging if the rotor is accelerating, increasing in rpm from a dead stop or from a standing rpm. Just a slight increase in rpm from an outside influence and the cap voltage goes up seemingly to match the rpm.

Below is what Im going to use as bobbins with 5/16x1/8 neos on the rotor. The washers and black plastic spacers are from ace hardware. I use a superglue that is called Tite Chairs. It doesnt say superglue, but it is very thin liquid and comes with fine precision tips that work well when ya get the hang of it. The plastic washers and spacers are roughed up a bit with 400 grit in the areas where the washers are fit to the spacer. The spacer has a flange on one end so just a lil pressure and a tiny bit of Tite Chairs and then the other end the washer is set flush at the end. It hods up very well for nylon washers and what ever the spacers are made of.

Looking to do 24 coils and try 24 alternating mags and using a bias mag for the reed so it only fires on N poles not S, or vice verse.

Im looking into rectangular coils also as I explain why in this thread below with pics. Just trying some things so far.

@Gyulasun and @Tinselkoala: thank you for your comments.

Charging of a 100 µF capacitor with the Back-EMF of the 6 coils in series:

(If you want to see the little six coil motor look at http://www.overunity.com/13523/has-anyone-seen-lasersabers-new-motor-runs-on-1000uf-cap/msg363434/#msg363434 , the six coils have a total DC resistance of 540 Ohm)

I am really astonished, the Reed switch allows a much better charging of an external capacitor than the MOSFET.

With the MOSFET (as a switch) the cap only charged to a little more than the supply Voltage.

With the Reed switch the cap charged to a multiple of the supply Voltage.

See the attached schematics, I am moving on to a second Reed switch in order to disconnect the 6 coils completely.

Greetings, Conrad

Hi Conrad,

Good tests, thanks and a possible explanation for the reed performing much better that it has no any shunt capacitor towards the negative battery rail like the MOSFET drain source capacitance represents (some nF in the low 1-2V  D-S voltage range).
What current consumption is involved from the supply when the reed is used?

PS Will be away from the internet for a week from this afternoon. Keep up and enjoy experimenting.
