JB Zero Force Motor - anyone building?

[MileHigh]

I really don't understand the animosity i'm sensing here or perhaps i'm being too sensitive.

Lots of people have issues with JB.  For example, in his clip, let's assume the supply voltage is 24 volts or less.  Brad's motor was running on something like 170 milliamps at 12 volts (I think).  Brad's motor is somewhat comparable to JB's motor.  I think in JB's clip that he claims that his 3D-printed motor runs on a few tens of mircoamps.  I don't believe it.  It's arguable this is just "aura projection" and has nothing to do with realty.  Just like the name "zero force motor" has nothing to do with reality.

When Lidomotor makes motors that run on microamps, they are usually tiny little things on needlepoint bearings.  You would damage one if you sneezed on it.

So there is a reality disconnect for you, hence many people have issues with JB.

I and others take issue with JB's misappropriated term "radiant energy" or "radiant spike."  There is nothing "radiant" about it.  He actually does not explain to his followers what the "spike" really is, and this has been going on for years and years.  If you don't believe me just factor in the fact that I just gave a "paper napkin plus" version of a fairly sophisticated pulse motor.

Minoly:

If I can ask you one thing, just spend a few nights researching about how a coil discharges its stored energy.  It discharges its stored energy in the form of a decreasing current pulse, that can assume a variable voltage.  That's in contrast with how a capacitor discharges its stored energy in the form of a decreasing voltage pulse that can assume variable current.

That's the "secret" that JB keeps under wraps.  There is nothing especially unique or amazing or "radiant" about a discharging coil producing high voltage spikes into a high resistance load.  If you spend a few nights researching this issue it should all become clear:  Just like a capacitor works to maintain its voltage level, an inductor works to maintain its current level.  Therefore (fixed current x high resistance) = high voltage.  That's the real deal, it's not mysterious "radiant energy."

Please go on a Google search where you look at four, five, or six discussions of this phenomenon and I am quite certain that you will get it.  Then you are going to ask yourself how JB doesn't talk about this and draw your own conclusions.

Brad's is running on 5 volts
JB's was running on 12 volts 1 mA
I don't need to defend him however he is only explaining things the way he sees them we can take from it what we like and move on with our own perception of reality,  or do the opposite of aura projection
I'm not sure what you mean by reality disconnect - that makes no sense to me without an explanation.
I believe we are all grown up here and can learn what we like from each other without having to proliferate animosity toward one another.

Hi Minoly.

The animosity is because of the rubbish they tell you just so as they can make a dollar.
Example-watch the video again,and listen carefully from 3.15. Here John talks about this bloch wall that dose not exist. He also says his motor is running at 12v 1mA. No way in hell is it doing that with that fan blade attached--the whole machine is 1 big lot of wind resistance.

He clearly states that the magnets are either pulled from the center of the coil out,or pushed from the center of the coil out. He also clearly states that there is 0 field at the center of the coil,and this is just not true. You need to understand that all this fancy rubbish talk go"s toward book and kit sales in the end--this is how they make there money.

So many books of secret's,but never one straight answer in them.
The radiant energy spike they speak of is nothing more than the collapsing magnetic field around the inductor(coil). The only way that radiant can be associated with it is that the magnetic field radiates out from the coil when a current is passed through that coil. This radiated field collapses,and causes an inductive kickback spike when the current flow to the coil is disrupted--nothing more than that.

Here is something to think about-->do you think it was JB that invented the transistor switched pulse motor as claimed?
Here is a little reading for you from 1969<--yes, in 1969 plans were out there for transistor switched pulse motors.

I am still going to moan about people saying "my pulse motor is efficient."  After years of building pulse motors you need to get some creative juices flowing.   You can't possibly compare an "efficient" pulse motor with a tiny rotor that weighs a few grams with an "efficient" pulse motor with a large rotor that weighs 500 grams.  So how do you address that issue?  Nor can you just quote current consumption without also quoting the source voltage.  You should be quoting input power - that's two birds with one stone.  Measuring power consumption vs. charging battery power is another interesting measurement.

What about how efficient your own pulse motor is at a given RPM?  I think air resistance is proportional to the square or possibly the cube of the velocity.  That suggests that more watts are required per unit RPM for increasing steady-state RPMs.  You could even plot that on a graph, just record the input power at say eight different RPMs and see if you see that air resistance signature in the plot.  Something akin to the power curves that you see for real motors.

The real thing for the efficiency game is having full control over the timing and finding the perfect sweet spot for the narrowest possible pulse width and the resultant least amount of power consumed at a given RPM.  Of course moving the reed switch around is a way to accomplish this, but it has its limitations.  The MHOP analog comparitor is a more sophisticated version of a reed switch.  Of course a microcontroller approach to optimizing the timing would be the Cadillac approach.

These are things that should be considered for a major build that you want to invest real time in  - but I am not sure about the spaghetti sticking.

My pulse motor consumes 60mw at 6000RPM. Pretty good for me
