Is this the first selfrunning overunity motor w/o batteries ? Mike?s motor

Wow, Peter.

That seems like a great deal even at 135 GBP! That works out to about $260 US. But of course they always get ya on the shipping.

Hope they accept your offer !

Re. the rotor, For RPM's less than 500, balancing is probably not so critical. Mike's doesn't look particularly fine-machined, but it runs fine at the rpm he is getting, which I believe is about 350-380 RPMs.

@ Dave,

Let me know how that transistor trial goes, and if no joy I'll design that other mod to auto-adjust Rb for ya. The larger Beta you can get for your Q1 transistor, (but not Darlington), the higher your top end RPM will be (to the motor's maximum) and still have the motor start. This is of course done in concert with the process I described earlier to find the maximum Rb value you can use. Give yourself 20% margin to be safe.

Hi Darren
lovely scope keep me fingers crossed.
Very interesting if i short the ssr out, it will start at low revs and work at low revs when voltage turned down, where as in any other configuration i need a lot more revs to sustain rotation.
If i leave the PSU hooked up, i could quiet easily do a Mike film, we will see if connecting the Hall up tommorow drops the current consumption, but has a similar effect.

PS being out of balance a lot cost me 2 volts min running voltage.

Peter,

Which configuration/connection are you using....yours or the original?

[Peterae]

Mine, but havnt done hall drive to ssr yet, so have just shorted the output of the ssr together.

Peter.

I guess as you say, it nust have been out quite a bit to make 2V difference. Mike's doesn't seem that bad, but there is a distinct knocking sound that can be heard in the video.

Looking forward to seeing your progress....get that scope!

Darren
