The Ossie motor

[callanan]

Just got A motor had been as low as 1.19 at lunch time it is now back up to 1.21 & bouncing back to 1.20. 90 hours running time

Hi Jimboot,

You are doing GREAT work regardless of your experience because what you have working and have demonstrated already is greater than many experienced experimenters and researchers have ever done!

The motor appears to like a particular operating voltage depending on it's construction parameters. Most builders will start with their motor running at a voltage that's either higher or lower than what the motor likes. If your battery voltage is higher than this point then as the battery runs down the motor should hit this point. If your battery voltage is lower then it will never hit this point.

The motor is essentially an AC device. So the frequency of operation and the matching impedance of the motor to the battery are important key factors in finding that resonant balance point where the motor just keeps running and running...

But I am not advocating that builders start trying difference voltages to start with. It is important to first get the efficiency as high as possible for your build in terms of the lowest input power possible for the best and reasonable rate of RPMs. IE, if you can get the motor to run on zero milliamps, then the voltage doesn't matter all that much then, does it?

One more thing for people to get used to in regard to extended run times. Depending on the battery type, batteries themselves have a built in self discharge factor. This self discharge factor is hightened when AC is sent through the battery. This is what this motor does. So even if your battery is discharging very, very slowly, you are still producing a greater amount of energy out of the motor

@Ossie:
Great to have you back with us. 

@Jimboot:
About that quote. I need some time to study it because English is not my first language and I don't wan't to missunderstand anything.
BTW: Your results are just amazing.

Have fun,
Frenky

Just can't bring my self to stop this motor! When I saw the volts had gone up I just had to tweak the reeds. I realise my own energy input into the circuit is tantamount to a hand crank but the levels are continuing to rise. An what point is my energy input negated?

The way I tune my Ossie is to hold the coils on with large self tapping screws. I then site the reed switches on the backs of those screws. The screws do 2 things for my motor that I have observed. They act as mini-toroid and as a trigger mechanism for my reeds. Whilst the motor was bouncing between 1.20 & 1.21 I realised I could switch to a 2V scale on the multimeter & get an extra decimal place -well duh I hear you say. I'm learning So I could se that the volts were cycling up and down. I thought about what Ossie said re getting your gen pulse larger than the activation pulse and moved the reed connected directly to the neg side of the circuit half a cm further along its terminal connected to the screw and made sure the glass of the other reed was directly in contact with the screw.

The voltage is now cycling between 1.223 & 1.227. It has been climbing steadily for the last 45min hour. In the last 15min it has risen .002 The gen pulse is a lot longer now as well. I'll take some more pix of the reed positions & upload. It just rose another.01

Battery at 1.236 now.

Wowww!!

this page is one of the best i have ever seen in this forum.



First thanks to Ossie to bring back here your fantastic  knowledge and experience

thanks Gyula  thats exactly what i needed to learn. I can now much better understand what is going on

Jb yes go on the good work

Frenky i am with you  i have just received my schottkys and some coils and a inductance meter


and now at work

bravo to all
