The Ossie motor

[Jimboot]

Ill do the other measurements tonight. The reason I hve the coils stacked is the motor runs more efficiently when I have them there I have no idea why. the negative on the meter I think means I have something wired backwards on the gen coil bridge/cap. I'll work it out tonight.

Im searching for a resource that tells me what the pinouts are on the hdd coil but have yet to find anything. So if anyone can point me at something that explains the hdd coil config it would be greatly appreciated. There are 4 pins and I am using 2.

The ampmeter is showing input current. the 6.3 is the SLA battery. I have only hand wound the bifilar coils. They are in series with the normal machine wound ones. Cant remember the cap value or schottkys but Ill have a look tonight & measure coil resistances and do a schematic.

Thanks for the infos.  Hopefully the negative on the meter can be 'fixed' with replacing its endings and the polarity from the bridge correctly corresponds to the capacitor polarity.

The pinouts on the hdd coil:  If I see it correctly in IMG_9512.jpg  you have 9 or 10 coils, right?  (Normally such motors were designed as 3 phase motors, 3 coils for each phase, then it had 9 coils but with 10 coils it had 2 phases I think.) 
Try to do the followings:  speed up the rotor and measure the generated AC voltages with your two channel scope across both pin pairs at the same time, no bridge or load connected to any output.
You say there are 4 pins (you used 2 pins), if you measure across the two pins you already used with one of the scope channels and you measure across the other sofar unused 2 pins with your scopes other channel and compare the amplitudes. You can see any phase difference between them too.  Here I assume you already know there is DC continuity between the other 2 pins too.  I assume the coils are in seriesly connected between the two pins you have used and surely the rest coils are also in series between the other two pins. With an Ohm meter this could be explored if all the coil endings are accessable somehow.
If you find the generated voltage amplitudes are about equal between the two pin pairs then you may wish to connect the voltage source in series (mind the phases) and then the summed output should go to the diode bridge AC input.  Probably you will find the drag on rotor RPM will double when you load the output, unfortunately.

Xlnt! Thanks Gyula ! The motor does slow slightly when lighting a bulb or charging a cap but there is no discernible change in current draw from the motors battery. That's the main thing that has me curious.

Thanks Gyula.
Here is the scope shot. The 1st trace represents what I was measuring in the last vid.

So the green trace is from one output pin pair, loaded by the diode bridge + capacitor and some load?

And the yellow trace is the unloaded output voltage from the second output pin pair of your hdd coil set, right?
