JB Zero Force Motor - anyone building?

Fusionchip's AKA (Gadgetmall's) first Bedini replication and "Piggyback Output Coil" looped selfrunner:

Compare Fusionchip's "Piggyback Coil" with neatpete45's "Ferrite Core Coil Induction" combination at 3:25 toward the end of his video:

This combination is "Lenz Free" because it does not involve rotor induction but "Ferrite Resonance"; The output coil is "nowhere near the rotor"!

Great-they just discovered induction.

@Tinman,

Probably watched some "Skycollection" videos!

I have watched many of skycollections video's,and while he builds nice neat machines,he never really dose any P/in P/out measurements.

@Tinman,

Very good point! Jorge's a skilled tinkerer who appeals to our intuitive reasoning rather then a schooled academic. He's shown us how to build his coils in the hope that someone with the precision scientific measuring instruments will help. Zerofossil fuel degraded him and caused him to take down all his videos for a spell. I helped cajole them back.

The concept is clearly demonstrated by neatpete45; Jorge maintains he has "Lenz Free" output coils. He's not talking about the pickup coil in adjacency to the rotor, but the coils behind it that generate power through induction.

Skycollection stacks at least four coils one over the other. He times the run of the neo sphere from a set of super capacitors. The addition of multiple induction pickup coils does not diminish the run time on the neo sphere!

I am going to discuss the torque issue just for fun.

When people say, "My pulse motor has good torque" it's purely anecdotal and meaningless.  The other thing is that when your pulse motor is running at a stabilized top speed, the useful output torque is ZERO, which may come as a shock to some ardent pulse motor builders.

The challenge is this:  How can you come up with a way to measure your torque, and also more importantly, compare torque between different pulse motors on a level playing field?

The good news is that this can all be accomplished with a pickup coil and experimenting with different load resistors.

Imagine that you have a special torque measurement coil that is a bit larger in diameter than a typical rotor magnet but relatively short in length.  Let's call it the TM coil.  So the TM coil would resemble a small ring for your finger.

Here is a typical example:

Say your pulse motor is running at max speed at 3000 RPM.   Then you bring the TM coil and chosen load resistor close to the spinning rotor and then the speed stabilizes at 2700 RPM.  You measure the RMS voltage across the load resistor.

You have all of the information to measure how many watts are being dissipated in TM coil:  The RMS voltage across the load resistor, the TM coil resistance, and the load resistance.  Crunch the numbers and get the watts.

So, at 2700 RPM and "X" watts dissipated in the TM coil + load resistor, you crunch the numbers and you get the torque output for your motor.  Foot-pounds or Newton-Meters, it's your choice.  As you change the value of the load resistor the motor will change speed, and it's up to you to determine if the torque increases or decreases.  Is there a sweet spot for the torque?

Finally, you can then create a metric that is independent of the actual pulse motor build: torque per input watt.   Two experimenters can build two completely different pulse motors and compete in terms of torque per input watt.

Finally, the bonus round:

The TM coil is shaped like a ring for a very good reason.   Imagine the TM coil is wound around a small circular piece of wood in order to allow it to hold its shape, even when the Lenz force on it is quite strong.  The TM coil can pick up power from two sources, (1) the spinning rotor magnets, and (2) the pulses from the drive coil itself.

You don't want the TM coil to be picking up pulses from the drive coil itself, that will disturb your torque measurement.  So without the rotor spinning, you connect a signal generator to the drive circuitry for your drive coil and start pulsing the drive coil.  You scope the output of the TM coil (no load resistor) and angle it in such a way as to reduce the pickup of EMF from the drive coil to an absolute minimum.  Now when the rotor spins the TM coil will presumably be only be getting EMF induction from the spinning rotor magnets.

So, the challenge for all you pulse motor builders:

(1) Measure the torque output from your pulse motor and find the sweet spot
(2) Calculate your torque per input watt and compare that will your peers in a friendly competition

Get your creative juices flowing and start making some real measurements of the torque instead of making meaningless anecdotal statements about the torque output of your pulse motors.
