but just think how this could revolutionize current electric motors for different tasks imagine your cd player or even portable DVD player lasting 10x's as long or your hard disk drive sipping power as if it were a mouse of current day ... This could easily lead to longer lasting batteries using current laptops or desktops even its really more then just simply a motor you could charge this capacitor then not charge it again until the voltage reaches "x" level or amount that requires a quick charge in doing so we have a very efficient motor more then anything currently available now...

Hi Jim,

I think I read that 1 Farad of a supercap is equal to 1 Amp Second. You are running on about 1.5 ma's?

A 55 Farad Supercap would give a rather long run I think. Sorry my friend.

You should look into Lutec's pulse motor generator. Interesting how they harvest the produced AC off of the same DC pulsed coils. It might be a way...

Cheers,

Bruce

Hook the pickup coils leads to the ac side of a bridge rectifier and the dc out to a cap. 100 to 1000 uf 16v or more.
Then measure the caps charge. And if you put a little light bulb or a 10ohm res, you can read the voltage and current to figure your watts out, as compared to your watts in.

Ok I've hooked up a coil from a rechargable torch. I have a 1000uf 35v cap & I have used a bridge rectifier (one I prepared earlier) that I made for another ossie circuit using schottkies . The cap quickly charges to 3.3 volts if I try hooking up a globe or a battery to charge tho my motor stops. Presumably because I'm altering the field in my drive coils with my pu coil current draw?

Anyway I'm thinking I should hook up a 2nd in series and that will give me over 6v that I can feed back into my drive battery? Maybe use a diode that only lets the current pass when over 6v? Once I get that happening - as long as I'm not dreaming I'll switch to a single D cell then try the supercap.

Yep I realised my mistake. A 45 min run. Nice but no cigar

Back to the pu coils.

Running 45 minutes just on one supercap is very impressive. 45 minutes is not 45 seconds. It's a lot of time! Very good!

Thanks but I'm looking for something I can eventually put in a Tesla sports car

I have no idea if it's impressive but I am at least impressed I have learned a lot

Back to work now.

Hey Jim
If the motor stops because you hooked up the charging circuit, then something was wrong in the hookup. I dont think that tiny coil would influence that motor as much as to bring it to a stop while running.
Also try a bit heavier wire for the pickup. It really doesnt have to have a lot of windings.
But thicker wire will deliver more current than thin.

Hi All,

Please see the following circuit below. I am getting great results with this circuit and find that I can get both batteries to charge at the same time. I can also keep replacing B2 with another battery until it is charged whilst never having to replace B1.

Battery swapping of B1 and B2 also works very well.

Regards,

Ossie

Ossie! Fantastic to have you back mate. I'll start replicating ASAP

Will you be adding pu coils next

gyulasun · « **Reply #414 on:** March 21, 2010, 09:10:47 AM »

Hi Ossie,

Would like to know if the switches are ON and OFF at the same time? (I think they are.)
Also, the two 100 Ohm resistances are the best 'compromise' for the batteries to 'see' each other?
This setup works in repel or attract mode?

One thing is: the more permanent magnets you use the more 'free' flux is available, it seems.

Thanks, Gyula

Hi Gyula,

Yes, both switches turn on and off at the same time and the coils are in attraction mode.

There is alot going on in this circuit which works particularly well with old sulfated 12V lead acid batteries who can still maintain their voltage but not much current!

Ossie

Ok got my motor up to 4000 RPM on 110 milliwatts tho - then the mags went flying

All better now. Put 2 of the little coils (tried to wind my own mags but go nowhere near the perfomance of these little guys) on & @2500rpm I get about 7.5V. So I will be adding another 2 tonight.

I still have a prob when I try & use the current tho. Even tho the pu circuit & motor circuit are not connected as soon as I try to run a bulb it kills the motor. Weirdest thing. The scope trace does not change either. The whole motor just stops. I'm thinking phase cancellation or some weirdness like that between the pu coil & drive coils.

gyulasun · « **Reply #417 on:** March 21, 2010, 11:56:15 PM »

Hi Jimboot,

May I suggest trying to arrange the pick up coils further away from the motor driving coils so that their own flux fields could not interfere. I know this may cause difficulties because of given distances and sizes but one thing to be considered is the fields may affect each other. Maybe to test this you could hold a pickup behind the rotor magnets, radially closer to the axle (if the rotor body lets it of course).
Another test may be if you have a small ,say, 6 x 6 cm i.e high enough surface, thin metal plate that you hold between a pick up coil and the nearest driving coil to shield them from each other? Some transformer laminations would be great for this test. I know this may cause some magnetic drug but it is acceptable.

rgds, Gyula

Still working on pu cois. Onto my 4th config now. One of the mags clipped a pu coil last night & sent things flying again. I haven't got much room to work with to get pu coils in there.

@Ossie
Whats scare me a bit in your setup is the primary battery, a 17A vs 3-5A secondary battery. Can you run the same test but with both battery of the same size just to be sure that the recharge effect is indeed real and not just a balancing effect between the 2 battery.
