Are Tommey Reed´s pulse motor circuits overunity ?

@powercat,

Reusing the motors wasted energy will help.
He also should look into the "rotorverter" capacitor tuning system for motors.

All in all, I think he is doing good research, and that is the important part.

....

So don't confuse pulsating DC with AC. This misunderstanding has bitten more than one of us in the butt  - just like the use of garden variety DMM's to measure amps or voltage at frequencies above a few hundred Hz.

@BEP
Good point. Pulsating DC is still DC. Besides comparing visual brightness is not a good way to decide which side has more, less or equal currents!

Hi Groundloop.
you are wrong,
You forgot to calculate the duty cycle into it.

In the last test at:

http://www.youtube.com/watch?v=lLOMUXEIiQg

he had a test at around Minute 3:00

where he measured:

ouput:
51 Volts
29.5 amps

and at the input:
92.4 Volts and 21 Amps.
Now he had the duty cycle about 50 % on/off
so the voltage must be divided by 2.

So he still had about COP= 1.5, so 50 % more out than in.

Regards, Stefan.

P.S. I agree that he has to measure the amps with a different measurement method
also involving low pass filters.
His digital camp ampmeter probably does not show the real values.
He needs to get shunts and also show scope shots.

Also his filming is much too fast. He should probably better use Google video,
where he can make longer videos and use a tripod and document the settings a bit longer
and show the screen readings also a bit longer and with more detail.
But at least he is building up a great system to research it !

New vid, it's getting interesting. http://www.youtube.com/watch?v=5LPGrg__26w&feature=channel_page
