Here is the conclusion of Matt's pulse motor affecting the power supply.

Thanks Luc,

So 40 hours and 69Wh for a single battery on the motor. Very comparable to the 3 battery test numbers.

Yes bi, I admit it's too close to be sure of a gain but to be fair, if we consider the battery charging losses in the 3 battery system that normally happens in lead acid batteries compared to the motor test connected to a single battery then we have to wonder why the results are so close.
At best a lead acid battery absorbs 90% of the power you put into it. So if we consider that, it kind of indicates there could be a gain.

The tests will have to be redone with the new lower impedance batteries I now have to come to a conclusion.

Looks good

11/07/17 5th and Final update of part 2 Testing the single battery Motor Run Time (stopped @ 8:20am)

For sure we can deduct 20 minutes off the run time to recover the motors overrun that brought the battery to 9.53 volts (below our 10v minimum)
With that in mind I come up to 40 hours total motor run time.

Are you guys in agreement with this?

During the course of switching polarity the coil still has forward motion (collapse), there is a brief moment that the energy is reversed and pushes against the power supply. This might cause the rise shown on the meter. Diagram below...

I built a boost circuit that seemed to mimic the motor action, which I posted some time back on the other thread, which worked reasonably well. I was speculating that the reversed flow, even briefly might create a charging effect on the high side. The motor coil and charge battery would become a series connection with a voltage that would exceed the high side.

I didn't build the motor so I really didn't have any comparison between the motor and boost circuit...

Sounds likely, maybe a diode between the psu and the motor would prove that.

Well guys, I did more tests and can't explain (with certainty) why changing the motors timing can increase or decrease the PS voltage reading

Thanks for your explanation Matt. I'll consider it.

Meanwhile, I tried a run of the Matt Pulse Motor at advanced timing to the new batteries. It runs fine but still heats to 125 deg. F after some time.

I think the heat is do to the timing.
My setup did not hold this morning but they rarely do with test leads.
I used to have 2 fluke meters similar to the one your using that I bought with my own money. I now only have 1 and its use is limited to very safe circuits.

I was trying to get my video uploaded, 13 hours later.

Thanks Matt for taking the time to make this video and your post details.
I appreciate you doing this.

Kind regards

Hi Luc,

What is happening in test 3?
As you change the timing the current changes but did you notice the voltage?
Any idea why it increases?

Cheers

Hi garrypm

I didn't notice that since I was busy with recording the demo and holding the motor together.
Great catch and definitely worth investigating further.

I'll give an update on what could be causing such an event.

The below are 4 are different test video's done to Carroll's "Matt Pulse Motor"

Test 4: https://youtu.be/mvQ47vuNmWM

Matt, can you please give a little feedback on the scope shot.
I'm thinking the timing should be advanced even though it uses more current to get a better charge effect.
With that in mind and considering the motors low coil resistance I would suggest to reduce the large 24v to 12v voltage potential to maybe a fully charged 12.9v battery to a 10.9v fully discharge battery, meaning we would only have a 1 to 2 voltage difference between the batteries which would result in a much better power transfer as far as watts are concerned since at this time a 12v difference between high and low battery cuts the power transfer (watts from bat 1 & 2 to watts to bat 3) in half which is caused by bat three's 12 volt drop. Just like the solar panel analogy I use as example to Dave.
Do you see my point?
So if you follow that then ideally we would want a motor that operates on 1 or even 0.5 Volts and still get torque out of the shaft (test 4 video) and close to full power transfer between battery voltage potential.

What do you think?

Luc

A lot of people create this scenario (IE joule thieves) thinking they are producing a transient similar to a monopole but is the furthest thing from it...

A true transient is not produced from the input power it is a bi product of the magnetic field collapsing and the charged particles that follow that collapse back through the wire. Most people don't really know the difference.

Matt

Bearden does indeed talk about compressing a material between two equal forces and then releasing does form scalar waves. He gives an example on the Bill Jenkins radio show, where he talks about squeezing an object between two fingers and releasing. Anyway...

Here is Matts post about the motor...
