Zero Force Motor Replication Project

[Yaro1776]

Greetings Alexelec,

The ZFM has progressed over the past two years as a viable driving motor (see the Advanced ZFM Explorations thread). The torque capabilities are outlined in the latest posts on that thread and have been improved progressively to the point that the ZFM will drive a small pump. There are no secrets here and the design information is shared freely.

The original ZFM design configuration is just an introduction to John Bedini's air core motor concept and once the basic principles are understood they can be leveraged to a more productive design configuration.

Be glad to answer any ZFM relevant questions.

advances, the zero force engine

Hi Drew --

To answer your question on a practical use of this Zero Force Motor. Our first project which Yaro has set out to do is to run
a water pump. My goal is to run a car alternator to charge batteries while the motor is running on solar cells. This motor once it is
at the high RPM's draws less current then a conventional motor. These are two practical uses of the Zero Force Motor which are
possible. I can tell you that at the 2017 Energy & Technology Conference this presentation on the Zero Force Motor kept everyone
there glue to their seats. I was there in one of those seats and I purchased the presentation information myself because it was such
a good presentation.

-- James

greetings, congratulations to all for sharing and contributing their advances, the zero force engine, achieves a lot of speed, as they have been demonstrating, but in the end you have to use the engine in something practical, move water pump, generators, etc,
From what I've seen that zmf lacks torque.
The idea of moving a car alternator for power generation is also one of my ideas, but to move the car alternator, some torque and speed are needed.
Mr. James McDonald does not know if he has succeeded in moving a car generator, which is what I also experience
but to move the car generator you need speed and power,

Dueling ZFM's

Hello to all and Happy Spring,

James McD and I had our annual Bedini fest where we devote three days to various experiments related to our current experimental interests. This year's fest was devoted mostly to the ZFM and we managed to accomplish many different and interesting experiments. The more interesting results will be presented in late spring and then in early summer at the 2018 Energy Conference.

The experimental results of a couple of them will require verification from other experimenters due to there unusual nature. These will be revealed at the Conference.

Anyway, James came up with a fun experiment where one would take the reversing polarity voltage that is fed to the ZFM's coils by the Bipolar switch and then also input this directly to an AC-DC power supply. The input to the ZFM's coils is a high frequency DC voltage that can be described as having an AC type of nature and the AC-DC power supply should convert this input to a DC voltage output that can then be fed to the another ZFM's power input. Whew! Will this work?

Well the JZFM was cranked up and the input voltage adjusted to 28.38v yielding 5315 RPM at 1.01A. The output from the AC-DC power supply rose to about 50v or so before the other ZFM was powered up. Upon power up of the other ZFM this AC-DC output voltage dropped to 28v or so. The other ZFM accelerated to 8074 RPM at 25.7v and 0.5A. The amperage on the primary PS jumped to 1.717A to reflect the increased load and voltage remained relatively stable.

So everything worked as James had envisioned and the experiment was a tremendous success and a very fun test. BTW nothing blew up and everything continued to run smoothly without any excessive overheating. No OU was expected here and none observed. Not all experiments end this well...

Interesting setups!

Hi Cristian,

Thank you for all your efforts to make these very interesting pulse motors and the videos on them. My heart was braking with sorrow when you put to pieces that 6 coil motor, LOL. But I know that your intention was to show everything and you did.

In your latest video I think you used again the same heavy rotor (it has 4 kg mass) what you already used in the pitbull pulse motor setup, right? It is interesting to compare the results of the two different pulse motors running the same heavy rotor mass.
(I think the pitbull pulse motor run at 9 V and drew around 410 mA and the RPM was around 1200.)

Greetings
Gyula

PS Here is a google translation of the above text into Spanish, to make it easier for Cristian to understand everything.

Hola Cristian,
Gracias por todos sus esfuerzos para hacer estos motores de pulso muy interesantes y los videos que aparecen en ellos. Mi corazón estaba frenando de dolor cuando destrozaste ese motor de 6 bobinas, LOL. Pero sé que tu intención era mostrar todo y lo hiciste.

En tu último video , creo que usaste nuevamente el mismo rotor pesado (tiene 4 kg de masa) lo que ya usaste en el pitbull configuración del motor de impulsos , ¿verdad? Es interesante comparar los resultados de los dos motores de impulsos diferentes que funcionan con la misma masa de rotor pesado.
(Creo que el motor de pulso pitbull funciona a 9 V y dibujaba alrededor de 410 mA y el RPM era alrededor de 1200).

Saludos
Gyula

Hi Christian,

It looks like your coils are turned 90 degrees compared to the ZFM. Is that intentional? ZFM has magnets moving from one pole to the other as far as direction is concerned and you seem to have one pole only facing the rotor.

[Gyula]

Hi Cristian,

Yaro wrote RPMs (in his post to you above) in the range of 5300 and 5800 for your motor setup shown in the above video but I think your meter displayed 2300 and 2800 RPMs, right? (His mistake was probably due to the upside-down meter display)

I wrote to you a personal message the other day, you can see it in the top side of the forum in the 'Notifications' icon,

Thanks, Gyula

Hi Yaro,

As has been shown a N pole is attracted to the S end of the coil. That is with the N pole over the coil

Whereas over the gap it has exactly the reverse motion, hence the bipolar switch being used

However, what if we could change the magnets polarity from when it is over the coil to when it is in the gap?

Easy enough to do. With the two coil setup the gap is actually too big to make efficient use of this, This is why I chose to go to six coils and six gaps of equal size. Then double up on the number of magnets. Thus when I have a N pole over the coil I have S pole over the gap.

Six coils, six gaps and 12 magnets per rotor. I pulse the coil only on a N pole being over a coil. The resulting action is to pull the N pole the length of the coil and repel/attract the S pole the length of the gap, a double power stroke for each pulse if you will...plus two rotors so both sides of a coil are used...

However it is a good generator and Lenz is still present so some of the claims are put in question.

Ron

Ron,

Good explanation of your ZFM design and its inner workings - can't argue with success. The only question that arises is the fact that the coils are being pulsed with only one polarity of voltage. It is somewhat vague within JB's notes as to the overall importance of the polarity switching to the coils at low RPM, however as the RPM is increased there are other variables that come into play. There have been a couple of interesting effects that have been observed, and documented, and posted in the depths of this thread. These may be attributed to the polarity switching.

With respect to Mr. Lenz and associated friends, well that subject has been covered by several experimenters and in the ZFM video. There is a Lenz effect evident in the motor - no question - really the point here is the magnitude. It appears to be on the low side from the o-scope screen shots in the video presentation...

I encourage you to continue exploring the ZFM.

Hello Cristian,

I did view your well done video - glad that you are willing to share your research efforts. I do have a couple of comments:
1) I assume that you were demonstrating the impact of the voltage increase on speed and the speed increase was noted as 5300 to 5800 RPM.
2) Not sure what you mean by "glasses coil" - I assume that you have encapsulated the coils in a clear plastic. Correct?
3) In the interest of international communication I suggest that you label your instruments with written tags (maybe on tape) describing the instrument reading volts or V, amps or A, etc... Language does not need boundaries when thoughtful video can be used. This also applies to the US members - Think Globally!

My best to you - nice work!
Yaro

Hi Cristian --

Your video link does not take you to a video but takes you to a sign in to You Tube.
Unable to see the video.

Ron,

Numbers look good with the Prony calc - I assume that the 850 RPM experiment was operated about 12V so the net torque is very decent. Looking forward to more information as you progress. Thanks for sharing your work results.

Thanks Yaro!

I used a Prony brake and the formula T X N/5252 to find the horse power and thus the watts out compared to the watts in

I forget the exact numbers at the moment but the result was 64% so rounded it off a bit.

Hey Ron,

Your progress on the I_Ron ZFM design concept is coming along nicely, and best yet it appears to be operating well. Your in depth investigation into the operating characteristics is definitely yielding results. Great work!

One question is the methodology used for efficiency - clarification would be very useful to all. Shoot a PM to me if needed.

Best to you in the New Year,

the north poles face each other, as do the south poles

when the north poles are over a magnet then the south poles are over the gap

The draw is dependant on the RPM ... it will draw 2 or 3 amps starting but this is reduced at speed

eg: at 850 RPM the draw is 1.14 amps... at 1350 Rpm the draw is 500 milliamps on 24 volts.

The efficiency at 850 RPM is over 60%

I do not understand your configuration very well, but if you lowered the consumption of 4 amps to 250 mA this is not only a progress, but to correctly connect the coils. It was not normal 4 amps to get only 750 revolutions.
If it is correct what I understand, then you had the magnets with the north for outside, right?

It really simplifies the electronics without an H bridge. Just an opto driving the TC4427 driving the mosfet.

I am using a TVS across the coils, which are now in series parallel.
