Are Tommey Reed´s pulse motor circuits overunity ?

[gyulasun]

At a cursory glance, as one would say, aren't calculations for pulsed power a bit different than the normal power.

What I mean is that hooking up the meter to the input and read it, then say "There, it uses x Amps at y Volts, thus we consume z Watts" might not apply in this case.

I have not looked deeper into it, but I would think that power usage would be a complex calculation of a sum of all pulses over a selected period of time.

As normal meters are not fast or capable enough to do this, a logging equipment would need to be set up that can record the pulses and sum them up in some pre-determined fashion.

What's everyone's take on this?

Hi,

I agree, using digital or even analog multimeters for measuring currents and voltages in case of pulse motors or pulse circuits can be misleading indeed,  I already wrote this in the first page of this thread, in Reply #6.

It is ok that he uses electrolytic capacitor at the output in his pulse motor or in his pulse circuits shown in the last few days but the charging and discharging current shapes are surely far from a normal sinusoid waveforms where the multimeters are normally dependable.  He should use several stages of low-pass filters to "clean" the waveform or make a good DC-DC converter that receives the output from his device and makes a stabilized DC output from it and this DC output should be used at the place of his input batteries.  Member 'poynt' here already uploaded a schematic on a possible output-input looping with an indicator LED to show any self-running state.

Thank's amigo
a lot of us here are thinking the same thing as you
this point was mentioned to him a few days ago on YouTube

@all
I have never seen anyone do so much in such a short time and so many videos
what a dedicated man Tommy is

Yes, he must use LC lowpassfilters to measure DC values instead of pulses if he uses digital meters.
I requested this on his youtube comments.

But I have also seen with my big Newman coil, that when I use a graetz bridge accross it,
I get a very fast chargeup of a capacitor from the BackEMF, so Tommy could be right,
that it goes overunity.
Too bad I just don´t have time and the space in this moment to test it further myself.

Stefan,

Where does the extra energy come from?  Because the flyback pulse's energy (the BackEMF in this case is incorrectly used term by many people)  totally comes from the input current to the coil.  All the magnetic energy that builds up in the coil by the input current will manifest in the collapsed field after the moment of switch-off.  Why can we expect more regained energy here?   
I agree that the amplitude of the flyback pulse can grow to as high as several hundred volts (-L*dI/dt),  it is a question of the rapidness of the switch and the current change. 

I wish any higher extra energy could be regained from the flyback pulse, higher than the input power,  hopefully Tommy proves me wrong by making a DC-DC converter to loop back his pulsed circuit forming a self runner.

Interesting question.  Could a coil that is pulsed with a DC current forming an electromagnetic field in the core material of the coil be forming a larger magnet in sympathy to the flux flow from electromagnet on coil 1? 

When the field from the long piece of core material collapses, if another coil is on the same core that was in the original circuit that was pulsed, could the pulse back become larger due to the response of the core material forming a sympathetic magnetic field and then that field collapsing on the coils? 

Another way to put it; can there be a gain from a pulsed coil and an additional coil that is not in the first circuit, if the magnetic core is larger than the first coil and holds the additional magnetic field and collapses the magnetic field on both coils for output?

Note diagram below.

Pulsed

BEMF pulse collected from both coils, but only coil 1 is pulsed.

It appears as though this is just a transformer and as I understand it, there is no gain, just a step up of voltage and a drop in current output in the coil with more turns...  But it may be operating different than a simple transformer, since the pulse starts and stops and then collects the BEMF pulse from both coils.  A core material that can hold a lot of flux before saturation, would enhance performance I would think.
