Confirming the Delayed Lenz Effect

[synchro1]

@Milghigh,

             So far everyone else has made a mistake but you. Twice the paper clips per gram of copper is "More bounce to the ounce". The way to run this coil with a Bedini circuit is like Gadgetmall does, with a third single wire trigger coil wraped around the bifilar. This gives you two leads from the Tesla electromagnet bifilar coil for power, and two from the single wire trigger coil for the four SSG connections. This Hybrid trifilar can't be beat for a pulse motor power coil.

The true Tesla serial wired bifilar coil, trigger wrapped outside into a hybrid Trifilar coil, Quadruples the efficency of Bedini's patented psuedo bifilar SSG, with 1/2 the wire for power.

Skycollection appears to power his spinners with the true Tesla pancake with trigger or Hall effect transistor.

This Hybrid trifilar can't be beat for a pulse motor power coil.

The true Tesla serial wired bifilar coil, trigger wrapped outside into a hybrid Trifilar coil, Quadruples the efficency of Bedini's patented psuedo bifilar SSG, with 1/2 the wire for power.

If you look over the discussion over the past day and apply it to understanding how a pseudo-bifilar coil will function as drive coil in a Bedini motor compared to a regular coil this would be the conclusion:

Both coils will work the same way, they will be indistinguishable from one another.  The main difference between the coils is that the pseudo-bifilar coil has the ability to store higher voltage and higher energy in the self-capacitance of the coil.  The capacitance in both coils is insignificant in comparison to the inductance.

When either type of coil is energized when the transistor switches on here is what will happen:  In a few microseconds the coil's self-capacitance will get charged to the battery's potential.  If you had a scope channel monitoring the current flow you might see a tiny tiny little pulse of extra current corresponding to the self capacitance charging up when the transistor switches on.  Then the inductance will take over and the current will start its slow climb up as the inductor gets energized and also pushes on the rotor magnet.

Likewise, when the transistor switches off the self-capacitance will slow down the slew rate of the back-EMF spike by just a tiny tiny amount.  If you have a reverse-biased diode across the drive coil to remove the back-EMF spike then you will not even be able to notice the effect of the self-capacitance.

This is a learning exercise for everyone and I hope some people get some benefit from it.  Believe me, I don't know all the answers, but basic stuff about the properties of coils is something I do know.  I think it's worth it to demystify coils and you have a lot of beliefs that many others share.  For example, many people believe that there is a Bloch wall inside a coil when that's not true.  So hopefully you will read over my postings and give them some serious thought.  Any pulse motor builder that is very curious about your proposition simply can make say a 200-turn regular coil and a 200-turn pseudo-bifilar coil and try them out in their pulse motor setup and see for themselves.

Thanks for the test by Gotoluc. He explains why high inductance in millihenries increases coil efficency. The Oldscientist measures 40x the inductance in the Tesla bifilar over the single wrap of equal gauge and length.

Synchro1:

I looked at Luc's clip.  I can't explain why he measures more inductance on the pseudo-bifiler coil when he states that the wire length is the same (which he confirmed with his multimeter).  It would merit further investigation.

The following explanation is a bit technical:  What he is demonstrating is that when he puts a magnet on top of the toroidal coil, it
interferes with the core material and reduces its effectiveness.  The magnetic field from the external magnet puts a "straightjacket" on some of the magnetic domains and "takes them off the playing field" and prevents them from flipping such that they can't contribute to the magnetic flux in the core anymore.  This results in lowering the inductance of the coil and therefore lowering the energy storing capacity of the coil.  That's the only affect the magnet has on the coil.

The inductance of the coil itself has nothing directly to do with the efficiency of the motor.  In other words, a bigger coil does not necessarily make for a more efficient motor.  If that was true then everybody would have jumbo coils.

Where the amount of inductance comes into play has to do with the timing and related parameters of the motor.  Bigger inductance means a stronger magnetic field, more energy storage, a bigger back-EMF spike, and a slower rise time for the current through the coil.
