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

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...

Hi DM
Would you be so kind as to run your flux sim on my rotor.
I think my magnets are too thin, with too much space in-between which may be causing my waveforms to be more pointy than normal.

Many Thanks

Hi Sam
just incase you missed my previous post Skate board wheels are 53mm and come with race low friction bearings  ideal for glueing magnets on.

I think so too.  I don't know if we can conclude that the pointy waveforms are bad, but I think the spacing is why yours are pointy, and why they flatten out between the poles.  I think your flux will look more like #2 in my earlier diagram.  It will probably affect how you have to set your hall sensor timing.

Hi All

I have been following this thread with great interest.
Forgive me if I am deviating from the topic,
(feel free to move my posting to a new thread if required)
but I think my question might be benificial to all readers:
What is your opinion on the Hans Coler 'Magnetstromapparat' and 'Stromerzeuger' ?
Apparently the Stromerzeuger  could obtain an output of 6 kilowatts indefinitely,
with an input of a few watts from a dry battery.
Unfortunately this device was destroyed in WWII but a British Intelligence report was declassified a few years ago
which confirmed the existence of this invention and independent verification by two scientists, and the report also includes limited schematics.

Refer http://www.angelfire.com/ak5/energy21/coler2.htm
Full report: http://www.geocities.com/CapitolHill/3752/hcoler1.htm

Has anyone on this thread already tried to replicate the Coler invention?
Understanding Hans Colers' invention can maybe assist us in better understanding what happened with Mike's motor,
or are these two inventions too far way from each other?

Sam,

After looking at your last waveforms, I can see what is causing the flattening of one excursion of your waveform.

It appears that you have one diode backwards somewhere, or that there is one bad diode. Could even be possible that one diode is actually a zener, or a bad diode that is zenering.

You will notice that when you use less magnets, the waveform becomes more sinusoidal (see L3_less_mags_37). This indicates that the amplitude of the waveform is causing a diode junction somewhere to conduct. You would see the same effect if you could somehow lower the windings, or increase the air gap. Try slowing the rotor down by hand while it is running, and I bet you'll eventually see a nice clean sine wave, with the spikes.

Anyway, I think the "problem" you are seeing has nothing to do with your magnet spacing nor the coil inductance.

Remove the fwb and spin the rotor by hand while monitoring L3 with your scope. You should have a more or less sine wave now. There should be NO flattening. If there is, then L3 is being severely loaded by something on this one excursion. If it looks ok, now insert the fwb again and see if your flattening returns. With a good bridge, there should be little affect to the wave shape.

btw, what are you driving on the output side of the fwb?

You are using a 10X probe, so I suspect that we are looking at 1V/div , and not 0.1V/div ? If so, then you'll notice your "clipping" is occuring at about the knee voltage of a diode junction.
