Has anyone seen Lasersabers new motor runs on 1000uf cap

@Tinselkoala: I think I came up with a simple way to allow for quantitative power consumption comparison (see the attached drawing). No actual numbers, but one time measurement should be longer in case power is fed back.

@Magluvin: the attached scope shot shows the slight mismatch of my two reed switches (one is exactly above the other).

May be the experts can explain why I measure no "power feedback" by the diodes in a "Ossi motor type set up"?

The attached pictures contain explanatory texts.

Finally I could measure without doubt that a feed back diode (or charging an external cap via a diode) consumes more power and slows the rotor down.

I used a circuit with just one Reed switch. See the attached drawing.

The 4.7 µF cap charges up to about 50 Volt (with the Voltmeter permanently connected, which is a small load). The rotor looses about 30% of its speed and power consumption rises by about 20% when a feedback diode is used (or while the 4.7 F cap is being charged, specially during its initial charging up to 6 Volt after being shortened).

When a white LED is used as a feedback diode the LED is shining and the circuit consumes 2.3 mA and the rotor is slowing down. (In comparison to the circuit without feedback LED when the circuit consumes 2 mA.)

On your second to last post, yes that is also what I mentioned with cap across the coils through the right diode.
On your last post, you said the magic word "symmetrical" that I will expand on below.

Sorry - corrected, I will expand on that in a later post. hehehe

@ALL

I think @gyulasun is very right about the coils not having enough inductance even if six are in series. So you always have to keep that in mind and not be totally disheartened by the results. Inductance moves energy.

Of course, in my mind when I chose 24vdc rated coils I was thinking with the right magnet passage, each coil  will produce 24 volts (hahaha). Of course if the coils were from a 110vac relay, the winds (hence inductance) would be at least 4 times greater to offer the same wattage handling as the 24 volt coil. But I will try these anyways.

According to @lasersaber on his 6 on 6 .....
"The coils seem to vary between 1.6 to 1.7K.  The resistance on the six coiler is 9.9K."

Compare those to my 480 ohms and I am 4 times lower then him. No problemo we will find the right coils.

@conradelektro

I will be out for the next 3 days so back on Monday to start my wheel. Thanks for your great reports of your tests but always keep in mind that coil inductance seems to be a key issue.

I see the reeds are not opening at the same time but the scope will give you a direct visible means to adjust them closer to same timing.

Looking at your last circuit I am wondering if the power supply itself is eating up most of any excess juice from the coils. I think you can try as shown below to first isolate the power supply with a diode. That will push any return to the cap.

I am also putting up a second diagram (one reed usage) but this one you have to very careful. You need to find the an inductance coil that will match or be higher then the inductance of your 6 coils in series. Notice I switched the polarities on the power supply. Also I lowered the uF of the standard cap and put your higher uF cap separate via a diode so it is now a real load cap across the coils. Please be careful with this circuit as any mistake has a tendency to blow things. The resistor is there as a safety. You can also put in a low amp fuse just to be extra careful.

The voltage on the load cap should rise very well. Then it is a matter of feeding back the juice to the feed.

When I say feed, right now it is your power supply but that could be replaced with an even higher uF cap that could then receive the power back from the load cap via a second reed (or maybe even a zener diode - Hmmm).

I this circuit, you may need to first rotate the rotor manually very fast before you connect the feed power so that the reeds are already switching fast enough to not create a direct slow short across the feed.

Back soon.

That second diagram using the Igniter/Ozone circuit wasnt quite right. Made the corrections below.

@Mags

Just got back late last night.

Sorry but my diagram is correct for the specific ozone patent 568177. It uses both the discharge on connection of a capacitor and the discharge of an inductor on disconnection to give two pulses while making sure the pulses are damped since for Tesla undamped pulses are always lost to the environment.

But again this method is very difficult to maintain because if the inductor is not of high enough inductance to create its own natural resistance, you will be producing heat. That's why I added that resistor in the circuit.
