ZFM Advanced Explorations

[Yaro1776]

The limitations of the thread software force the splitting of the post. Continuing;

So from an energy perspective the input to the motor from the battery bank yields 24.9 watts, while the motor output for the given load and RPM on a 0.500"D shaft yields 9.8 watts. Overall, the COP is 0.39 for the entire ZFM system.

The YZFM in its current configuration will yield up to 25 watts of output with appropriate tuning. For the time being the ongoing experiments will focus on low speed tuning.

The ZFM odyssey continues...

Happy New Year,

Hi Yaro,

The post before your last one was the longest it would let you post? I think it is setup to allow much longer posts.

Hi Yaro,

Aaron,

In Advanced mode when a certain length is exceeded the Preview post comes up a blank page. Same issue as earlier this week, however by deleting text and sentences the preview will come back when the text is a certain length. May be just an issue for my computer set-up or it may just correct itself.

Yaro, I verified that any member should be able to post up to 10k characters per message.

It sounds like the forum bugged out, which that exact problem has only happened in Energetic Forum once in a blue moon but I have seen it myself but do not know why it happens.

I apologize for the inconvenience! Especially when I can't do anything about it.

For many posts, I usually type them into a text document (to eliminate formatting code from MS Word) and the paste it into the forum in in case there are any issues with lag, connectivity or the forum itself.

Hello to All,

The previous Torque Test video was executed with a timing configuration that was essentially balanced from a push-pull perspective. Another way to describe this configuration is by stating that the Attractive and Repulsive forces were essentially balanced, but with a Repulsion bias. If one visualizes the 90 degree arc of the ZFM coil each pole has a given polarity that is switched back and forth by the timing. N-S, N-S, etc.

In Attraction mode the motor Neo is pulled to the opposite polarity and in Repulsion mode it is pushed away from the same polarity. Energizing the coil and having the appropriate Firing Angle (Coil on time) allows both modes to drive the motor as it rotates between the induced polarities within/outside the coil. Hence Zero Force motor...

The driving or energetic force within the motor is the Repulsion aspect (Yang). For example if the timing is way, way biased to the Attractive aspect (Yin) the motor will lock up in position - it cannot be rotated at the higher voltages.

Rotating the firing point 90 degrees brings the motor Neo to the same polarity - all Repulsive force. The motor rotor cannot be kept in this position as the input voltage to the coil is increased - it just moves.

So any astute observer would attempt to balance these forces for maximum performance of the motor. Well in this instance the balance point or neutral zone between the coil polarities yields the maximum motor efficiency. Interestingly the Bloch wall resides within or is this neutral zone. From the Bloch zone the electric magnetic fields emanate into their complementary polarities. The Neutral line or zone!

More to come,

Hello to All,

The last set of experiments were completed over a week ago, but the flu malaise and battery problems have slowed things down. Two of the four 100AH Labs are losing their ability to hold a full charge - these two were recycled from the local car repair shop and have worked well until now. Instead of purchasing two new LABs, a 60v 10A DC power supply was ordered to give a more stable and consistent voltage for the testing. Delivery is some time next week.

Anyway, I_Ron did execute a number of experiments and video a month or two ago with the coil polarity and attraction/repulsion. See this work on the ZFM replication thread - excellent and informative!

The latest YZFM experiments were geared to define the best efficiency points at 15 degree intervals with torque, speed, amperage and voltage as the data variables. The starting point was the locked rotor position (all Attraction).The preliminary results do point out the following at 24v input:

1) There is an observable band of approximately 20-25 degrees span where the best ZFM efficiency happens - essentially, from about 40 to 65 degrees of advance from the locked rotor position. Relatively balanced between Attraction and Repulsion.

2) The maximum observed speed occurs in a very narrow band around 85 degrees of advance - the amperage is substantially higher than that around the best efficiency band, amps are nearly doubled. Nearly all Repulsion at play here and the speed can oscillate unexpectedly in this zone. It is possible to push up to and beyond the 90 degree advance point with significantly diminishing returns in performance and speed.

This particular oscillation point, around 85 degrees of advance, has been noted in all the rotors tested to date and pointed out in the 2017 ZFM Conference Video. A general point of interest where the motor is basically operating in full Repulsion mode - it was dubbed as the "Bedini Effect" at the time as an identifier. With the smaller Neo rotor the advance could be moved plus or minus 10-15 degrees with minimal impact on speed (around 12,300 RPM). Very curious results...

So the above gives some sense of the play between the forces of Attraction and Repulsion. The interaction of the Neo's magnetic fields and the coils' electromagnetic fields is not antagonistic, but complementary.

Best regards to everyone,

Greetings from the North Country,

The woodpile has been steadily decreasing and cabin fever has started to take its toll. Over the past year Ron Cole's Notes and sketches have been published on the air core coil concept or Faraday Motor- see Posts #13-#19 on the Bedini Magnetic model thread. Intrigued by his collaboration with Bedini, Cole conceived of an Air core coil motor influenced by Bedini's ideas. Several experimenters have commented that it would be useful to replicate his air core coil motor. This may be the first replication.

Bored to distraction by the weather it seemed like a good idea to give this a shot. Research into the Cole concept revealed that the existing YZFM could be easily modified to accomplish this. A number of Aluminum rotors and Neo's were on hand along with the necessary components to modify the timing and other small important details. Over a week span the plan came together.

So this motor was put together with an existing Aluminum rotor and (2) 1"Wx1"Lx3/8"T rotor Neo's placed in a N-S twin pole arrangement. Very similar to the YZFM configuration for the 2017 conference, but with only two opposing poles operational. So the timing was set up such that the firing or coil power on time happened twice per revolution or every 180 degrees.

The major difference is in the coil wiring. The ZFM has a very balanced arrangement as the rotor progresses around the circumference N-S-N-S, while the Cole method uses N-N-S-S. All in combination with the Bedini-Cole Bi-Polar switch. The induced external magnetic fields of the motor are very different.

Amazingly the motor turned on first power up, albeit in a rather primitive manner. The first start-up did rotate, very much untuned and below are the results for the nominal voltages:

24v 764 RPM 1.00A
36v 1103 RPM 1.02A
48v 1675 RPM 1.30A

So over the next day the mission was to tweak the performance and here are the first improvements:
24.1v 2440 RPM 0.66A
36.1v 3940 RPM 0.74A
47.9v 5900 RPM 0.72A

Progress for sure - some observations on run mode are that the motor is a bit flakey with large spikes of voltage and amperage. Definitely no torque for this configuration. More tweaks...

For the third set of experiments the video camera was set up to record for posterity the R. Cole Motor. Anyway, the video speaks for itself and there are a number of unusual behaviors exhibited by this motor, but further investigation may have to be delayed until much later since the ZFM work is in the forefront.

Yaro, Thanks for your continued explorations and postings. I am happy to see someone talk about the LCF motor. To understand it well and make use of it better, it helps to know your TEWARI. perhaps deserves its own space. As a lurker.......

Dennis,
Thanks for the positive comment on the explorations and the pointer to Tewari and the SPG. All Very interesting! Note this is the R. Cole two pole version, not the 6 pole LCF. I will place future research on this subject onto my calendar for later consideration.

Greetings to all,

Before putting the R Cole replication mod to bed until a later date the thought occurred to document a more detailed look at the operation and basic design elements.

This video demonstration illustrates all the basics of the design and a short operational run to point out the pulsing action of the internal play of the magnetic fields. This motor, while similar to the ZFM, has its own peculiarities. One may assume that the torque of this machine can be improved using the methods/mods explored with the ZFM. As of now the torque is very low. So the door is open for others to investigate and experiment with the R Cole air core motor.
