The Ossie motor

[captainpecan]

@ Jimboot,
Did you purchase your coils prewound somewhere, or did you just make a very well crafted coil with perfect inductance as to what Ossie was using?  If you ordered them, could you share where you got them from?

@all,
The reason I ask is that I know where I can order the coils that Ossie is using, but I would much rather order a spool and make many coils.  Problem is, the coils I wound are not right.  They are 20 guage I think, but when I measure them they are 1.4 ohm each.  Ossies I think was .5 ohm each.  So what size wire has anyone here used and got the desired results?  Mine still perform well, but the battery never goes up.  I am also not getting a higher generator voltage than the run voltage which is exactly what my problem is, hince the reason I need more info on the coils.

Also, any details on magnets would be good for other replicators.  That of course is another part of my problem, I need to add more or stronger magnets.  Got that handled though.

Overall, keep the replications coming!  This is great stuff guys.  I'm still tinkering with my orbo replication, but to be honest I just don't get the performance I get with my Ossie motor, or even my regular bedini for that matter.  I really think the Ossie motor is where it is at.  It's easily replicated, and a great project for a beginner in this field.  It's almost easier to get results than the SSG circuit.

I've got some awesome additions to my circuit I will be sharing shortly, but I need to get my coils and magnets right so I can test it before I post it.

Have tried Ossie but with two coils only.
Seems ok, running for long time; maybe with 4 coils it gets better…

Great work!  There is a problem with the schematic you show in the video though.  I assume it is just a drawing error, but if not, you may want to fix your circuit.  For proper recovery of the collapsing field, and to protect those reed switches, the diodes need to be hooked up on the other side of your reeds.  Check the attached photo to see what I mean.  The way you have it in the schematic, your reeds would be arcing, which is not good for them, and a clue that you are not capturing that bemf. You've probably got it hooked up correctly and just drew it wrong though.  Good work though, nice to see another replication, each one is different with new clues to the puzzle!

Just got home. OM running at 310RPM 1.21V 67hours running time.

Hi guys.

This is probably one of my happiest days because J.L. Naudin is thanking me on his website for the full-wave rectifier idea. I have been following his work for about 10 years now and I have great respect for him.

@captainpecan:
Ossie and Jimboot are using this coils:
http://www.jaycar.com.au/productView.asp?ID=LF1326

Specifications:
- Inductance: 1.8mH
- (L)DCR: 1.05 Ohms
- Wire Dia: 0.8mm
- Core: Air

I will make coils by myself because there is no way I could wait for the package to get from Australia to Europe.
I also got all the material for Ossie motor so over the weekend I will be able to do some testing.

@captainpecan
I got the serial number from the coils off Ossie's original vid & since he is an Aussie I know he shops at Jaycar. So I got them there. You can also order directly from them here http://jaycar.com.au/productView.asp?ID=LF1326&keywords=lf1326&form=KEYWORD If anyone is going to buy from Jaycar in Frankston ALL the staff there are now familiar and educated in the the Orbo & Ossie MOtor & have seen a working demo of the Ossie. Also some of the staff in the Cheltenham store are now familiar with the principles   They currently have a shortage of reed switches tho oops! SPreading the word. Trying to get more replications happening.
