Pulse motor - is this overunity?

[mr2]

I have made a small pulsemotor that is inspired from EV Gray. It is only made to verify my theories. And has a very small energy consumption.
All persons i have demonstrated this motor for, says that i may only done a motor efficiency better from COP 0,2 to 0,4.

Therefore i have disconnected the motor. Replaced it with a 33 ohm resistor. Putted on 0,1 ohms resistors as shunt before my invention and one after the invention. Then i put a oscilloscope on the shunt and measured the RMS voltage.
I have attached a small schematic to show my measurement method.

Pulse rate only 2 Hz.

My question is: IS this overunity? And is it correctly connected/calculated?

At R1 the scope said 3,67mV RMS. With the formula P = U^2/R this is 0,1346 mW
At R2 the scope said 5,23mV RMS. With the formula P = U^2/R this is 0,2735 mW

This gives a consumpion over the load 103% more than the load from battery.

input 440 mW
output 90 mW

Way underunity.
The input is calculated by the 12 Volts x (Voltage at R1 / 0.1 Ohm), so it is 440.4 milliWatts.

Output is 52mA ^2 x 33 Ohm.

Thanks for answer.

Is not the formula P=(U^2)/R correct as powercalculation?

Well anyway...
The voltage is same on both from battery and outside. So then the outside should be calculated as 12 Volts x (Voltage at R2/0,1 Ohm) = 627,6mW?

@mr2,

3,67mV = 0,00367 Volt.
5,23mV = 0,00523 Volt.

Input current  I = U/R = 0,00367 / 0,1 = 0,0367 Amp.
Output current I = U/R = 0,00523 / 0,1 = 0,0523 Amp.

Input Watt     P = U * I = 12 * 0,0367 = 0,4404 Watt.
Output Watt    P = R * (I*I) = 330 * 0,00273529 = 0,9026457 Watt.

COP = OUTPUT / INPUT = 0,9026457 / 0,4404 = 2,0496042234332425068119891008174

It seems that you have over unity.

Are you 100% sure you have measured true RMS values?

Groundloop,
not 330 Ohm,
but 33 Ohm,
so underunity !
