Mostly Permanent Magnet Motor with minimal Input Power

[gotoluc]

Hi Mags,

okay I see

The problem with Zeropoint132 test is similar to what I was trying to tell synchro some posts back.
If you wind a coil with many wires together, 4 in this case, the coil ends up being 4 times the size. So now if you energized only one wire all the other stands cause 3 times more space between the energized wire turns and weaken its magnetic field since the turns are not concentrated and as close together as possible.
I'm quite sure if you took the same length of wire and wound it alone in a nice Brooks coil the magnetic field would be stronger then it being spread out like that.
So to me his test is not valid unless he had made a single coil to disprove this possible problem. Better yet, he should of had 4 individual single filar coils and place them one after the other to prove there's a benefit.

Come to think of it, my first Super build test 1 uses one of two strand is possibly suffering of the same problem ... I'll need to recheck that!

Hope you understand?
Let me know if this makes sense

Hi Mags and all,

I can now confirm what I described above is exactly the problem.

I retested my super build coil by connecting both wires in parallel and the pull force is 2.56Kg. so 60g. better then with the two leads connected in series using the same 0.43 Watt

Hey Luc
So you reduced the input voltage for the parallel test as compared to the voltage for the series test to come to a common watt figure?

Tesla projected magnet waves from his series bifilar by impulse. D.C. current adds no magnetic strength to the winding. D.C. coil magnet strength is a function of wire length, thickness, and number of turns regardless of configuration.

I pulsed a tightly wrapped machine shop series bifilar with a welding rod core, and attracted a set of carving knives from far accross the kitchen counter. I ordered a sloppy lash wrapped version from Rick Fredrich, and noticed a dramatic reduction in magnetic strength.

Connecting the power coils series bifilarly, then pulsing them at the self resonant frequency will increase the magnetic strength many times per joule, over the straight D.C. magnet strength!


What the hell is bifilar bipolar?

Yes, it was 0.63vdc and 0.682 Amp = 0.43 Watt

Hi everyone,

I just completed the 100% efficiency test on the Super build by using a fixed Joule energy input calculated by Khwartz
post: http://www.overunity.com/8429/mostly-permanent-magnet-motor-with-minimal-input-power/msg418177/#msg418177

W [J] = 2.35 [kg] × ~10 [m.s^-2] × 1/1000 [m]

= 23.5/1000 [kg.m^2.s^-2] = 0.0235 [J]


In my test I placed the Super build vertically so the coil is against gravity.
I used a Capacitor bank which I checked with my Capacitance meter to measure: 7170uf

I charged the 7170uf cap bank to 2.56vdc =  23.5 Millijoules

when the coil was energized by the Capacitor bank it moved up about half of 1mm

If anyone cares to check the numbers and Math to see if all looks right that would be helpful.

Thanks

Luc
