Counter Electro Motive Force from an Inductor

Hi Norman

What a very very great article you found here talking about converting standard motors to overunity devices using a second set of commutators brushes and harnessing the CEMF.

It is all so easy to understand and makes perfect sense all the way through. I have been "preaching" some.of these concepts and ideas for over twenty years...this person taking it to much more understandable levels.

The 2nd set of brush commutator idea really works well and I have done lots of succesful experiments with them. All I can think to add is he calls for 2nd set of brushes to be "phased" I would add for the timing to be "delayed" a bit with the 2nd set of brushes and this is what he calls "phased" I will guess.

I found about 5 degrees retarded, like an echo, as to when to connect 2nd set of brushes to load or caps gives super good results and the frequency or rpms of motor will decide the exact connection point....also have 2nd switching share same pulse width length with primary pulse width...but just delay it a bit, the 2nd switching. I really like the author saying to input sawtooth DC pulsed in transformers for example, as now the primary will have the CEMF to harness as well as secondary, because of the cut off of current up there at the peak.....and to use this in generators too... in my mind do not input or output "smooth sinewave AC instead chop in and out sawtooth so you can always harness that CEMF.

Anyways thank you so much for that article very inspiring for me at least. Would be fun to know author but not on need to know list...


Something they don't tell is for it to be more effective winding must be WYE to eliminate self shunting and be OU its easy just cut one end of the wire in the commutator segments in any dc motor rotor and solder it to a common ring,,,,, you can do that is small motors also .... voltage capacity will double.

This i had posted long ago, but people don't read, many just are here to sabotage and distract and others are just collecting information on devices used to make them into useless pieces of shit....

the only thing i say to this people is don't ask for me when they are burning in hell...



A lot of history here behind this concept. You were there with me at the KeelyNet Conference where I had the EV Gray Motors disassembled and explained the inner working of same. In the YouTube video you will see that I pointed out the additional contacts in the commutation slip rings that captured the CEMF sending the spike energy back to the battery source. The motors were powered by DC pulse energy.

I started my research on this idea way back in the early 80s by buying plans from John Bedini for the Tesla Switch using a DC motor with the 2 gel cell 12V batteries being switched in the configuration explained by George. I had extended the motor shaft and had 4 sets of slip rings to mechanically switch between supply and load battery.

DC saw tooth input so you can switch off input power at the saturation point of the BH curve just at the point where the coil impedance drops to an air core coil value as Ole has explained. When an inductor goes into supersaturation the impedance drops. It is at this exact point that you want to switch from supply to load output so as to capture the spike energy of decaying magnetic field. The idea of using a locked rotor configuration falls directly in line with my 5 HP motor set up that gave me the Neutral Spike output. Isolation from supply power with spike energy going into earth ground. This proposal sends the spike energy to a load or back to supply battery.

BTW, John Bedini was sitting right in front of me at the Conference presentation and I asked him to verify some info that I was discussing. That was a great Conference which gave me the opportunity to meet you and see your work in this area. This idea of variable impedance creating the pumping effect falls right inline with the Hyde Patent where that configuration dealt with variable capacitance giving the same pumping effect.

If you take a hypothetical capacitor of X-value of capacitance and charge it to say 1000V and instantly drop the capacitance value to zero (hypothetically) the voltage would go to infinity. Same with an inductor of a high Henry value loaded with magnetic flux energy and you suddenly change the Henry value to a much lower value, you have in effect multiplied the energy (voltage & current) which we see in the ferroresonance phenomenon. It all makes sense when you think it all out. It has been measured at ferroresonance a transformer winding will have voltage spikes at 10X the supply voltage and current magnitude greatly multiplied. Just a matter of capturing that energy and make it do work for us.



That is likely what was happening when I daisy chained 10 big dc motors using fwbrs fed 35 volts and ending up with more than 90 volts at the last motor. Doug's idea regarding the rectifier on the brush leads seems to have worked even better than expected, when multiplied over several separate motors. The tread mill motors have a double ended shaft, which makes an extra commutator easy to install. Is this just a mechanical switch timed after the power on sequence to the coils, directing the resultant high voltage of the sudden open, where ever you wish? Perhaps the additional rectifiers supply this same function?

Cheers Warren

Hi Warren

Could be the additional fwbrs in the motor daisy chain downstream cause a delay effect also the FWBR instead of single diode as is normally done to capture the CEMF makes for a juttering delay and machine gun release of the CEMF as opposed to single spike blast. (Maybe)

My theory (one of them) about the delay of connection causes the timing of CEMF spike to line up and cohere with the inherent back emf force at its.peak of " opposing force", and the spike is so sudden and of such high voltage it knocks a chip off of the inherent backemf forces which releases itself from its natural-job of opposing the forward EMF and now this "chip off the block" of backEMF goes in same direction as the spike energy and is rectified as well riding underneath and supporting the spike energy, so there becomes a sudden large current along with the spike ...that is, if the timing is just right when recovery circuit connects which is about a 5 degree delay in time I found with my motors.


Hi Hermes,

People have been trying this for ages, and it isn't OU. If it was, we'd have had evidence for at least half a century.

Read and think about the principles I've talked about there. It's not impossible to produce an OU system, but you need to use the correct principles in order to actually achieve it.

Best regards, Simon
