Mostly Permanent Magnet Motor with minimal Input Power

Luc:

Did you consider doing tests where the coils were first connected bifilar, and then you redo the tests with essentially the same coil configuration, but monofilar?  Same number of turns, same gage of wire, etc.  From a cursory observation of what you are doing, there is no logical reason whatsoever for a bifilar coil configuration to be different from a regular coil configuration for this setup.  You basically have a large electromagnet with a large inductance picking up a large weight, and whether the setup be bifilar or monofilar, the coil capacitance will be minuscule and totally insignificant and have absolutely no affects whatsoever on your tests.

The important principle to understand here is to take stock of what actually affects your experiment.  It'd just like the thread about myths and misconceptions for magnets.  There may be a specific narrow set of cases where a bifilar coil will make a difference, but for a brute force electromagnet the expectation would be that a few extra nano or microfarads of capacitance will make absolutely no difference in the performance of the electromagnet.  If you don't agree or believe me then simply run the tests for yourself if you are so inclined.  It's simply not right to see people make clips where they make their coils bifilar when there is no logical reason to do so - it's just another myth.  The inductance of the electromagnet is the elephant in the room.  The capacitance of the electromagnet proportionally might be the size of a fly on the elephant.

With respect to the efficiency of doing the lift, I asked you where all the lost energy went.  Gyula mentioned the resistive losses in the wire which I agree with.  Here is another thing to think about:  As the capacitor discharges it is building up the magnetic field in the coil.  So for a certain number of milliseconds as the capacitor discharges, there are i-squared-R losses in the wire, and energy is going into the coil to build up the magnetic field.  Before the weight even moves, the electromagnet is building up in strength.  So that means you have resistive losses in the wire, and there is energy put into the coil, before the weight even moves.  Both of these components will factor into the losses.

LOL Gyula, at least you're interested and will take the time to comment.

Just checking to see who's awake here

Thanks for your post

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.

Sorry Synchro1 but that is just another nonsensical fantasy posting.  I don't want to disrupt the thread, but that is the honest rebuttal to your posting.  You have made other fantasy postings in this thread that disrupt what is going on.  I will ignore them from now on.

You are a supercilious and pompous ignoramus of the first degree!
