The Ossie motor

[futuristic]

@woopy:
Very nice work.
About the rectifier... I also think that you should make one from the BAT42 Schottky diodes as they seems to be perfect for this type of motor.

Hi Woopy,

I do think you can keep your fence wire results in this thread too, for it is a variant of Ossie motor and this thread is about the Ossie motor.

I am afraid the circumstances at STEORN DEMO LIVE thread have changed and some people consider the Ossie motor there as an off topic.

Ossie clearly expressed his opinion on this:

- In regard to the motor I am showing you relating to this thread, my perspective is that it was born out of this thread and should remain here as a reference to the benchmark of performance that Steorn has shown us so far. Until they show us superior performance of their motor to my motor then I think my motor should remain here in this thread were it was born.

While I agree with his opinion, I am afraid the circumstances may affect Ossie (and some others) mood on appearing in the STEORN thread and if this is so, it would be a big loss for all of us. I do hope he sooner or later will write again in any thread.

Re on your diode question, Frenky answered and I could add that in a diode bridge it is always two diodes in series that are conducting so the forward voltage drop doubles, hence the importance of the diode types. Old germanium types, though hard to find and expensive, could also be considered, but four BAT42s are also fine.

Hi Frenky and Captain

don't worry there is no shorting at the battery.

I tried the Futuristic fullwave bridge on the Ossmot and its works fine. As the scope trace (between the coil entry and the + of the bridge) was interesting (see picture), i tried to hook a super cap 2.5 +2.5 10 F (see on the right down side of the picture)

After having charged it with the 4.5 volt alcaline , i disconnected the battery and let the super cap works on itself. After one hour the motor spun very slowly and i stopped the experiment.

  Than i reconnected the battery at 4.60 volts and 256 rpm  and this morning after 9 hours the battery is at 4.56 volt  and 251 rpm   Good result but not enough at the present. But i am waiting for finer diodes and perhaps with a schottky bridge

wait and see.

Just for fun i enclose a new version of the Fence wire coil Ossmot.  Nice torque with  1200 RPM with the orange prop and 7.2 pulsed volts at  1.2 amps. I have made 2 loops of fence wire so i can modulate the torque by coupling in parallel the loops. I will try a third loop to completely cover  (shield) the magnet and see the result.   
I founfd very instructiv that even if the magnets are partially covered (shielded) by the fence wire coil, the system works
In which thread do i put this one ?

Regards

Woopy
nice fence wire motor.  Those mags look like you could try to wrap them as toroids. That would be interesting. =]

You are doing fantastic work!

To measure I/O energy just put 1 Ohm resistor between + of the battery and the wire to the circuit.
Then measure voltage on it with scope and you should easily see input/output energy.

Have fun,
Frenky

Thanks!
I'm at 48.5 hours on my d cell. I'll let it run overnight & tmrw night (20 hours) I'll get a scope shot for you. I'll have to stop it to do the test so i'd like to give it one more day. Unless I get my new one running in the meantime!

@woopy I love your designs mate. I own & run a successful Aussie Internet marketing company during the day, so I don't have time to replicate your designs but keep them coming The motor I'm building now is focused on creating a better tuning mechanism than my last motor.
