Mostly Permanent Magnet Motor with minimal Input Power

Hi MH,

Today I found there is a difference between the coil connected in parallel vs series.
In today's tests the best efficiency results for the coil to move up against gravity was with it connected in series. However, I think the gain could be mostly from the boost in Inductance. Gyula suggested a way to measure the Inductance and the results are 8mH vs 30mH in series. So I think this would need to be considered.

Today's tests
All tests done with low voltage.
To maintain a stable low voltage through the coils power stroke, I used a 650F Super Cap fully charged and stable at 2.7vdc 
By using this low voltage the coil moves up slowly and resulted in less losses as these were the most efficient results to date.
Using the coils maximum upward travel stroke of 23.5mm it used 1.2J connected in parallel and 0.94J in series.
If we use the 0.94J and we subtract 0.54J which would be the unity amount needed for the coil to travel 23.5mm (if my calculations are correct?) then we are left with 0.40J under unity.
However, by having the coil travel to the maximum height I was able to collect (in another cap bank) 0.32J as the coil fell back down with most speed.
So if we deduct that we are basically 0.08J under unity.

So it looks like at best around 90% efficiency.

Now that it's confirmed the device is Under Unity, can you please help me to rate it as it's ideal work solution, a Solenoid.
There must be an established protocol to test Push or Pull force vs power and stroke to rate the efficiency of a Solenoid as I've found charts in some solenoids pdf data (see below)

This would be of most help

Thanks

What MileHigh fails to understand is that the series bifilar coil has no magnetic field inside the coil. The coil vectors a monopolar magnet wave like a smoke ring, with the positive pole nested in the center. This field forms outside the coil when pulsed.

Facepalm.

Well, not much luck finding anything with the coil connected in bifilar series and using high voltage discharges. Voltage and Current seem to be in phase.
The current sensing resistor is a carbon 1 ohm 1% resistor. Voltage probe is no.1 (green) and current probe is no. 2 (yellow)

The Scope shots below range from 50vdc to 1000vdc and cap value from 16.66uf from 50 to 250vdc, 10.16fuf rom 300 to 800vdc and 3.44uf for 1000vdc
Each pic title has the details. The recovery is from the diode as the coil falls back.
I did not bother with the coil height measurement for each test as they were all higher Joule energy for the height reached then when using low voltage. Basically, the higher the voltage the more Joule energy it take for the coil to travel up. The coil wants to go up faster as the voltage increase but so does the generator effect increase at the same time. So more and more energy is wasted as voltage goes up.

I'm not going beyond 1kv as the coils wire insulation could be compromised.

hey Luc

Thanks for doing the tests.  So 2.8ohm series coil and 1 ohm current sense.  Do you have a lower ohm resistor?  Say 0.1 ohm or lower?   Just thinking, in the series winding, that resistor is consuming 1/4 of the energy from the cap. And in parallel, .7ohm coil 1 ohm resistor, the resistor is consuming more than half. This will definitely throw off comparisons of the 2 coil setups I think

Like if the resistor wasnt there, then we would have to worry about connecting wires and switch resistance. If there were an inrush discharging into the bifi coil, 1000v/2.8=1357w max possible. At .7ohm coils in parallel, 1000v/.7=2428w,  all just resistance values, inductance is in the way.

Tesla talked about discharging 40kv and getting what, 10000hp. Thats 7.5MW.          If that energy were only for an instant,   7.5MW/40kv=187.5A   40kv/187.5A=213.3ohms  That is if inductance whasnt an impedance. Pun 

Anyway, thanks again. I want to try some things Ive thought of with all this. See if I have time.

I tired and off balance like my text. Just babbling.

In other words, its possible that the parallel might outperform distance wise than series if the resistor is not there at all.
