Tommey Reed's OverUnity Experiments
« on: November 03, 2014, 06:16:51 PM »
Hi All,


OK I'm doing testing on overunity  experiments

This is very interesting test running a 240v 5hp ac motor with a dc 120v inverter , I believe BEMF is at play here.

Hi Tommey,

what's happening is your AC clamp meter is designed to read amps with a sine wave input. So when the inverter is hooked up, its output is a modified sine wave (looks much like a square wave) so you AC clamp meter won't be able to display correct data.

The motor while running off the inverter is consuming 262 watts
11.94V x 22A = 262 watts

The motor while running off the AC grid consumed 215 watts

Your plug in AC power meter is picking up noise from the motor caused by the modified sine wave running the motor, so its data is also not reliable.

All the best in your experiments

Hi Luc,

I also ran a 60w light bulb as a filter in parallel with the ac motor and still had the 115v@5.5 amp on the meter, so it seem to be doing something else.

I didn't know a bulb could be used as a filter?... I wouldn't think it would change the MSW TO SW

Does it do the same if you put an AC 20uf or more motor run cap instead of the bulb?

The problem is one of measurement accuracy.  If one wants to measure AC power accurately, then one needs a power analyzer instrument with enough bandwidth to handle the frequency harmonics contained in the AC power waveform used.  DMMs and simple devices like a Kill-a-Watt are subject to substantial errors when any:

The AC power is not sinusoidal.
The load is reactive.
The source is reactive.

Two of three of those factors are in play here.  If you have a digital oscilloscope and the right probes for looking at the AC mains safely, then you could export the voltage and current information off to Excel and calculate the power to the accuracy of your probes and the vertical amplifiers in the scope.

Hi All,

This is another overunity test, no free lunch with this belt drive system.

Yep.
