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

Hi Darren
The meter who knows, it was high spec bench meter i bougth about 25 years ago LOL.
I agree there is no way im going to get an acurate reading.
Ive just put a rubber bung on as a small fly wheel and glued a magnet on it, just finished re balacing for the magnet, only put 1 on at moment, i can alter the timing by undoing the nuts and turning it, im going to mount the Hall sensor next and power this seperatley and hook upto a home made frequency counter to moitor the rpm, i have to say that before when every thing was hooked up and the SSR was engerized it went a lot faster and lower current, it will be real interesting to see what happens now it's balanced.
Looking forward to the scope arriving, if you want a link to ebay item let me know.
I had an email saying it was shipped today.

PS connecting the cap does not make any difference to the rotational speed or sustainable speed,makes the current a bit more steady.

I was thinking about the magnet arrangement on this motor.  It seems like there are two basic possibilities for the flux pattern, per the attached sketch.

Depending upon the spacing of the magnets, it looks like one of the two situations will occur.  I'm not sure why this is bugging me, but it is.  Has anyone given any thought to this?  Any comments?

Hi
DB
its beyond me at the moment,im wearing my brain out testing LOL.

Cap only connected 4.5v 25mA
Cap + FWB + main coil hooked to FWB no apparent change to V or I
SSR shorted 4.5v 40mA much increasing revsm which allows me to turn down v to 4 v at which it draws 35mA.
Not tried the SSR switched yet.

No... Thats actually not what the flux fields look like on that kind of armature. The flux will flow from one magnet to the next to form a ring. Your flux drawing represents a monopolar armature. If you post the magnet dementions and materials/grade info, I will run a flux simulation tonight and post it here.

My drawing is (supposed to be) like the armatures typical of this motor.  6 magnets, poles facing out, alternating.  I don't see how this will form a ring.  I guess I'm not an artist!
