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

DB,

I think your sketch #1 is what you're going to see. As there is more spacing between each magnet, there will be flux loops within the same magnet as well as to the adjacent magnets.

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!

Could you give me a rough length/width/hieght/material of each magnet?
Then I can SIM it later in FEMM, and post what the flux looks like...

Most people are using magnets that are approximately 3/8 to 1/2" thick, by 1" by 2", #8 ferrite, I think.  Some have rotors where the magnets are almost touching at the corners, others have maybe 1/4" space on each side of the magnets.

Some are using the "Radio Shack" rectangular magnets that are about 1/4 thick by 3/4 x 1 or so, and stacking two of them.  I do have some of these magnets that I could use.

Hmmmmmm... Interesting flux patterns...

So the waveform shape changes when you stack more magnets?

Keep your 150 Ohm coil around in case you want to try it again later.

Are you going to wind your next coil like Peter's?

Hi Darren

Regarding the magnets affecting the waveform, I was trying different things to see if I could get rid of the flat bottom on my waveform for L3.

Nothing seemed to effect it ? different diodes, transistors, resistors, etc. When I placed some small neo?s on top of the rotor magnets, the bottom of the waveform started to curve. See shots attached. I also removed one of the two stacked ferrite magnets from the rotor to observe the effect.

My next coil is gong to be L1&L3 -#30 @40ohms, L2 -#28 @46ohms which is as far as I can determine what Mike had. I will also be using the Radio Shack magnets he used.

Incidentally, I was playing with comparisons to Mike?s D2 scope shot and found that if I flipped it both horizontally and vertically, it looked more like one of my D2 shots.

Cheers
