Are Tommey Reed´s pulse motor circuits overunity ?

@chrisC,

Based on the measurement in his videos, yes, you are correct.

I have modified my test circuit with a hexfet (IRF840) instead of a regular transistor (2N3055).
It seems that I can not loop the output directly back to the input because the internal resistance
of the lead acid battery is so low that it is a short circuit for the captured back emf.

So if we want to do a full looped back test circuit then we will need a impedance match at the output
and to the input.

Regards,
Groundloop.

Thanks. As Tommy pointed out, at 30% duty cycle, the OU efficiency is even better!
Hence, giving back the % that will allow the loop to recharge the batteries will indeed make it perpetual and still do more than useful work!

I assume we can capacitively couple back some of the back emf charge. It can be done since Tommey now has proved his point.

@all

My question is:

Is he using an in circuit PWM ? Or He is using an outside PWM ?
If the PWM is from the outside then there is not OU.

The PWM is run from the same 12V in the system. That's where the 168 ma is measured. What is the point otherwise?

Thank you @chrisc

Does you or anyone has the circuit for the whole thing with the PWM included?

Conceptually, it's very simple. 4 fast diodes of the 4007 type, a single primary of a coil transformer, fast drivers for the 3055 power transistor and large caps rated 200V to collect the back emf. The PWM is probably any single chip PWM capable of 10K.

why no one discovered this back emf captured to a capacitor and filtered for useful work beats me?

The thing is that we are looking for the circuit that has a PWM and is working in order to replicate it. The one kindly posted by @groundloop here: http://www.overunity.com/index.php?topic=7241.msg174681#msg174681 does not have the PWM circuit or chip number included.
