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

I thought I would post the results of some experiments for rotor weights and flywheels.

The motor is setup without the 3rd coil or extra cct connected. I have my meter connected to the 3rd coil (reading AC volts) and am useing it as a tachometer or crude way to see energy produced. I am assuming voltage from the 3rd coil is a good indicator of speed and energy produced.

All tests repeated 3 times. Motor spun-up by hand and readings taken when they had settled back down to a constant voltage for 30 secs. Rotor is rubber wheels from a printer with 20mm*10MM*3mm neos stacked 2 high. Stacking the neos to reduce air gap and slight increase in mag strength made a HUGE difference. Motor would not run under 5.5 volts with just one neo and drew about 50ma. Now running at 3 volts and much less amp draw.

Voltage across 3rd coil. (connected only to meter)
With no extra fly wheel I read .89 volts
with 80 gramm flywheel I read .68 volts
with 180 gram flywheel I read .48 -.54 volts and motor is struggling

I can see no change in MA drawn by motor , but it is now running at insanely low Ma and it is very dificult to get an accurate reading. My amphere meter is 1 amp max and the needle is moving about the width of the needle from zero. I have no idea how accurate the meter is however. For some reason putting my multimeter in series with powersupply doesn't work.

Well it's not earth shattering but does tend to go against Mike's advice to use a heavy flyweel , so I thought I would share as some may now wish to experiment with total rotor weight as a result.

Ok got me coil done, Quad-Filiar
coil 1  25.1 Ohms
coil 2  24.8 Ohms
coil 3  25 Ohms
coil 4  40.1 Ohms.

240 Turns.
Cant get a picy untill tonight, forgot to take camera to work

PS. the Inductance meter is on its way, but can take 1-2 weeks.

It is a great indicator of speed.  It may or may not have anything to do with energy produced.  If you are not able to draw any current from the 3rd winding, no power is there (.89v times 0amps = 0 watts = 0 energy)

A very interesting test would be to add a resistive load to the third winding and see how it affects the motor.  Start with about a 1k resistor (less than 1ma load), then drop down to lower values and see what it does to the current and speed of the motor.

If you don't have an ammeter with better resolution you may not be able to tell anything conclusive though.  Your multimeter may have a blown fuse in the ammeter circuit.  This is a very common problem.  You might check if it has fuses inside.  This would give you a better check on what is going on with the current.

Hey Peter,

I'm glad to see that the Ohms worked out pretty close to the predicted values.

Which meter did you end up buying? Mine is supposed to take a couple weeks also.

Hi Darren
Same one.
The inductance and capacitance meter.
I looking at a digital PC Scope next.
