The Ossie motor

[Jimboot]

@ossie Back to Jaycar tmrw A daunting circuit for me! I like the way you've seperated the coils tho.

1.259 volts 96.5 hours 243Rpms Midnight here going to bed

OOps was just filming another vid & bumped the reeds. The motor stopped. I fixed the reeds & restarted. Oh  well I suppose 97.75  hours is ok. I have taken the opp to reposition the neg switch even closer to the coil battery at 1.260

Hi all

I have installed the shottkys (BAT 43) as a per original Ossie design  (no fullwawe bridge) for a first test.

Than i have concentrated the tuning on the CURRENT curve .That is i  inserted a 1 ohm resistor between the battery plus and the entry of the circuit. The stick probe on the plus on the battery and the croco probe just after the resistor.
So my best result until now is that trace, (pix 1) which shows a very short and low impuls, with a negative curve (prabably charge inpulses ??). Which , If i have right calculated (thanks Gyula  explanations) should roughly represents 3 milli amps at 4.44 volts that is about 13 milliwatts.

And the probe on the coils give the second pix trace. The impulse is something out of the gen curve and give a 10 volts very short kick back spique)

Now i am making a test and we will see what happens.

for info

my coils are  resistance 5 ohm (each)      inductance 3.94 mHenry (each)  about 40 meter of 0.4 mm copper wire

neo mag  diameter 20 mm    10 mm thick   N42

the rotor is a RC car wheel  (60mm diameter )  mounted on a HDD drive motor without magnet and winding (no cogging at all)

Reed switch  250 volt 1.2 amp  in serir with a 10 ohms resistor  (at entry) to reduce the current  (these resistors must also be tuned)

Schottky diode BAT 43



@ Jb

I have noticed that you have mounted the coils of your new motor with metal (ferromagnetic material). Is it right? if yes don't you think this could interfer through the air core and change the result ? Just for info

good luck



Hi Ossie

What is this new circuit. Does it mean a new motor with driving coils in serie and trigger coil as per your Orbo replication ? Or is it a solid state Ossie generator new project  ??  Thanks for sharing

hello
good work on the motor..
if you want to use diodes instead..
use the Schottky diode BAT 46
it has better stats than a Germanium Diode
it has a lower foward volt than the 43
but it also will go 100 volts

have fun
it looks interesting
