The Ossie motor

[captainpecan]

@techieatwork The maths are a little beyond me at this stage which is why I'm taking the physical approach of tweaking & tuning. However I agree with you. It is finding the right frequencies for the rotor and also the switching. The circuit I had running for over 100 hours charged my battery. Before the run it was 1.32 it is now resting at 1.43. I achieved that primarily through tuning. Angling the coils & positioning the switches. My circuit is still using non-schottky diodes, no resistors or rectifiers. I believe the gold is in the tuning. Welcome aboard & thanks. I look forward to the responses of those more qualified than I.

Two things I find very interesting about your setup are... First, your generated voltage does not appear to be higher than the pulse voltage from your scope shots.  So I'm not real sure your landing any of that generating voltage into that battery.  And second, you are using a disposable battery I believe that is not designed for recharging.

Even with these two things possibly going against you, you are still getting awesome results and the battery is going up.  Now of course you must be getting more coming back on the collapse than you are putting in, maybe entirely from the bemf adding to the pulse.  The most interesting part is the fact that I cannot come up with a CONVENTIONAL theory as to why you are getting those results.  Unless of course we later find that most of that voltage on the battery ends up being surface charge, then I think there may be something else happening here that we have not put our finger on yet.  But I do not think it is surface charge because that battery is under load constantly, and surface charge does not like that very well.

The point in bringing this all up, is the fact that when you get your motor tweaked with all the goodies, and it's generating more voltage from the turn than the pulse, your motor could get really interesting fast!  Remember, you have not even started using pickup coils or anything to make use of the rotational energy!  Your knocking very hard at the door of OU, eventually the door is going to open...

Thanks CP. I stuck my rechargable D cell which I have yet to recharge as I forgot to buy a Dcell recharger. It reacts differently to the alkaline. In a good way. Whereas the alkaline would cycle up & down over 4  values over 7 mins before climbing to the next value the rechargeable only bounces between 2.

Today I tried 12mm OD metglas squareloop toroids inside my aircoils on OM2 but no joy. I also have not had much luck with the optimised circuit. I have tried it on 2 machines but I just ca't seem to tune tune it. The circuit is firing in the coils but the tuning for it is not the same. I have tried 2 other batteries on the OM1 and the behaviour is very diff even at the same volatge. like Ossie said in an earlier post. I am currently charging a AA that came with my tacho at 235RPM. Which is good because I don't have a AA battery charger.

Vid I uploaded last night.

Stefan made a point in the vid about the polarity of the coils. I didn't see anything in Ossie's circuit about polarity so I just hooked them up. Assuming that the inside lead is positive here is the polarity of current setup (pun intended) they in  are in series  -+ +- -+ +-

Hi jb

very good looking bravo

I am now testing the output  of the schottky bridge     so i have disconnected the plus and minus of the bridge to get directly the output of the coil generation     and untill now my best result is 15 % of the total input  and i wonder if the power to spin  the rotor  makes the difference to go on the grail (OU)

I am trying different voltage and it seems that at each different voltage the timing must be tuned and can be dramatically in or out  the purpose for what we are seeking.

I think to try the solid state switching of Ossie , but i need some parts doc.
so far i see   i imagine

Trigger transistor NPN   2n2222A 
power transistor   NPN   2N 3055  with a 10 k resistor at base
power transistor   PNP   MJ2955
poti 5 k
and 7.2 nominal volt  ??

And now i am wondering if my coils, with an inductance of 3.94 mh each and 5 ohm resistance  are OK . as the Ossie and JB and JLN are 1.8 mh and about 1 ohm ??

Anyway a  very instructiv weekend    pefect under snow and in front of the scope

good night


just forget  did you pay attention to a recent post of LARRY C on the steorn thread about a torroid ala Ossie with one wired shorted.  Have a look 

perhaps why not for a fence wire Ossmot ??


good nigh
