Are Tommey Reed´s pulse motor circuits overunity ?

[powercat]

His latest video at:
http://www.youtube.com/watch?v=GzS7MN_u-54

shows exactly that this system with the small motors are NOT overunity.

Otherwise you would have at the motor side
always a higher current at the same 12.5 Volts supply and output Voltages.
But it is not.

Or you would have a higher Voltage at the same amperage. But you also don´t have that.

So it is clear now, that this system at least with these small motors is unfortunately not overunity.

Hi Stefan
Tommey has so many videos and measurements it's as clear as mud to me
but in his second too last I felt the grooup was convinced of OU

NOPE his system already has a pre-smoothing cap bank from the battery. This averages out the demand from the system so all those pulses are now averaged out as DC well close enough for good measurements.

SOyou example 0.116x12x0.5=0.7W. is actually 0.116 * 12.8 volts his battery is not 12v dead. = 1.4848 watts i/p

"Now, this is at 50% duty cycle, at 30%, the results are even better! The average current measured at the battery & PWM side is quite accurately measured. The load side is stabilized by large capacitor(s) and delivers what that motor needed at 12.5V. Even if the real current measured is off by 20%, it still delivers much more power?"

WRONG i/p power is still smoothed showing demand via caps therefore whatever his  clamp meter shows is the correct reading on battery cable. There is no further requirement to take into account PW. If the efficiency changes as a result of PW change that's something different.

"The unloaded capacitor voltage spiked at 115V but settled at 24V useful voltage and runs the motor at 68ma (assuming it's all DC) giving a power at 1.63W . That's proof of O.U!"

Well with a demand of 1.63 watts and 1.4848 watts i/p its OU with 146 milliwatts spare. Certainly wont win any prizes with this and too close to call parity with measurement errors.  ALL back EMF system is OU by design 1.618 * Q but his system losses and bad matching losing OU.   Never get it looped either need a system with at least  COP>3 to loop.

Basically all he has made is a buck boost converter depending on load and supply demands. If i see  10 watts in and 30 watts out then he is on to something interesting.

I explained earlier post optimal PW is 38.2% fibo. This is why Tommy see 30% better then 50% but he dont know the math or reason.

@Bolt

Thank you for the clarification. I guess if those measuring instruments already computed and averaged out the currents then the results are not O.U. I am still learning about measuring instruments and techniques.

@all
In Tommey's latest video he has gone small-scale
is this making a difference to the OU measurements

Thats a northstar 10kw 3600 rpm 2 pole generator head. I wonder if he is using 110 outlets or 220 outlets. If he could reach loaded 110 operating ac and could use 40 amp battery charger to loop it back. Maybe I am missing something.
