    Mid Winter Diversion - Ron Cole twin Pole Rotor N-S Neo's

    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.

    May the Snow be with You,

    ZFM Complementary Forces - Part 2

    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,

    ZFM Complemetary Forces - The Yin and Yang of Polarity Part 1

    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,
    Yaro

    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.

    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.

    Torque Demo Take Three

    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,
    Yaro

    Toque Demo Take two

    Hello to All - this was written on Jan 1 and delayed by a series of comm and software problems;

    The New Year was welcomed in by stepping outside for a short walk - well sir, the -15F temperature rapidly evaporated the fuzzies from the earlier celebration. Turned out to be a very short walk...

    The previous post's video demonstrated the poor man's torque test device. Seemingly crude, but it does produce consistent data that can be chewed on. The YZFM was configured in a very mild state of tune - meaning the operating RPM was a relatively modest 6,275 at 0.34A and 37.75v without any applied external load. This point, FA (firing angle), was selected because it displayed the lowest amperage draw within a narrow range of RPM along with the fact that the coil firing was initiated around the center point of the coil.

    From this position retarding the FA will increase the amp draw and diminish speed, increasing the FA with advance will increase the RPM and amp draw. This happens to be a relatively neutral and happy location.

    For demonstration purposes a modest load was applied to the running YZFM by sliding the high tech weight along the lever arm to yield 300gr of force to the 1/2"D motor shaft. This action immediately reduced the speed down to 5,025 RPM and increasing the draw to 0.66A - a very stable configuration. The next step was to bring the motor to a full stop by removing the power and then restarting the motor under load. Done and no problem. The motor started up and stabilized speed with the amp draw nearly identical to the previous run. Go to next post.

    Hi Yaro,

    Just wanted to let you know that I finally ordered most of the presentation videos from the 2017 conference and really appreciated the new information, insights, and John's lab notes from your presentation. I also greatly enjoyed watching your talk and the way you presented it. Great job!

    I've been regularly following your progress with the ZFM in this thread and am very interested in your progress even though I seldom comment. The ZFM is one of several machines I still want to build, but seem to run into too many distractions. Plus I need to get back to, and improve upon, the attraction motor plus low drag generator replication I started some time ago.

    Happy New Year,

    ZFM Torque Testing Demonstration.1

    Happy Holidays to all,

    The end of the year pressured me to finally execute A ZFM Torque video just to give all a flavor of the process. This post will be fleshed sometime after the "2018 Party".

    The video may have a few rough edges, but it does get the point across.



    Happy New Year,

    Hello to all,

    Some definite speed bumps in my free time for experimental work. Real world intrusions and battery problems in the early part of this month have put a crimp in my video plans. Anyway, when I have had an opportunity to have some play time I continue to pursue minimizing the input to the YZFM. Decided to look more deeply into the design of the motor and assess the impact of the numerous variables. My sense is that the motor is not fully optimized and continues to fight itself. It is very evident, at least to my perception of the motor in operation.

    So going back to basics, the firing angle was tuned in to about 60-65 degrees of coil on time (coil energized). This is a reasonable and comfortable area with fairly predictable results with small changes in advance/retard of the actual firing point within the coil 90 degree arc segment. Complex sentence for sure.

    Anyway, from a result perspective at nominal 36v input voltage, with some manipulation of the firing angle and advance/retard, the motor was able to run at nearly 7,900 RPM at an input of 0.3 A. Using the actual voltage the input power was 9.99 Watts.

    It has become increasingly evident that the output power of this motor can be manipulated to yield about 25 watts. Input voltage, FA and Advance play a large factor in the power output equation. The goal here is to minimize input and maximize output

    The only way that some of this can be explained is through a video. Definitely in the works and assuming no major time demands from the outside world. The torque measurement device and associated output power will be demonstrated in the very near future for this aspect of the experiments.

    No time to play....

    Upbeat ZFM for Cyber Monday

    Hello to All in the Provinces,

    So after the last series of experiments and the so-so results the experimental test plan was modified. Initially speed was the focus and this obviously was not a winner for COP. The Big Al rotor needed some encouragement, so the timing advance and firing angle approach were modified in the quest for more efficiency.

    From prior experience the firing angle (FA) was reduced (not measured as yet) and the advance retarded progressively. This resulted in an increase in overall efficiency (COP) from around 25% to 40%. Mega gain!

    This motor does become gutsy as the timing is modified, though still maintaining the 40% efficiency.

    For 36v: 4,572 RPM @1.07A with a 515gr load; output 15.73 watts, overall efficiency 40%. Not too shabby for a home built motor.

    Next was a dry start under a 540 gram load. Can the ZFM do this? No problem - this dry start yielded the same efficiency. The motor produced 15.79 watts of power at 4493 RPM @ 1.11A.

    So what are the next steps in this experimentation process? Stay tuned, for sure a video is in the making...

    Happy Cyber Monday,

    ZFM with 1-1/2"Lx1"Wx1/2"T Neo's

    Hello all,

    The next step with the YZFM was to machine an 1-1/2" long Aluminum rotor to be outfitted with a 3/8" thick Neo in keeping with the experimental progression. Not to be, the search for this thickness with a 1-1/2"Lx1"W was unsuccessful and a 1/2"T Neo was substituted. The prior testing and anecdotal testing strongly suggested this would improve the torque of the ZFM.

    The big Neo's are a handful and require focused attention for proper assembly. For ease of assembly the Aluminum rotor had a 1/2"Dia steel pin inserted through the center. The Loctite 332 structural adhesive was used for attaching the Neo's to the Al rotor. The first Neo was simple to position, however the opposing Neo was more challenging - hence the steel pin and this helped. After attaching the first set of Neo's the assembly was clamped is a wooden vice. The next two Neo's were installed very carefully using wooden shims to slide into position. Another wooden clamp was used on these Neo's and the assembly allowed to sit for about an hour before curing - temp in my outside work area was a balmy 29F.

    The rotor assembly was placed into a Pyrex bowl and covered, then wrapped with a towel for insulation. This was set on the Barbeque grill and heated so that the internal temperature was 130F-140F and then cured for about 3 hours. Bear in mind that the maximum recommended temperature for the Neo's is between 170F-180F. Exposure to higher temperatures will degrade the magnetic capability of the Neo. The final step was to wrap the rotor with three layers of fiberglass shipping tape after mounting and positioning on the shaft.

    The motor was proofed progressively at higher speeds and voltages (12v, 24v, 36v and 48v). Immediately obvious that the timing and dwell needed to be modified with the new rotor. The FA (firing angle) was reduced to 50-55 degrees and this helped immensely. The advance adjustment has become much more sensitive over the prior rotor.

    Anyway, the motor definitely has more torque and will still achieve the same speeds as the prior assembly at 36v, albeit with a greater amperage draw. The bottom end torque is impressive, particularly at 48v.

    So for no load 36v; 10,186 RPM at 1.16A, nearly double the prior rotor. Okay let us look at an example of the developed power, but at a more working and useful RPM.
    Small rotor 5,099 RPM at 1.16A; output 9.98 watts with a 300gr load - efficiency 23.84%
    Large rotor 5,111 RPM at 1.60A; output 14.64 watts with a 440gr load - efficiency 25.41%

    The above results demonstrate that the modification of the rotor/Neo length to equal the coil width has great merit. The 48v testing has shown the same type of result. The larger rotor has a very obvious quirk at higher speeds for both of the higher voltages. At about 85-90% of max RPM there is a sudden major acceleration accompanied by about a 10% increase in amperage draw. First time is a bit unsettling, particularly at 48v, when the RPM jumped to 12,700 RPM.

    The tuning process is not quite complete. There is still the sense that the motor is fighting itself.

    Happy Cyber Monday,

    To Torque or not to Torque

    Hello all,

    The torque testing of the ZFM is a very essential component in determining the performance of this motor. In keeping with the low budget nature approach, the testing process was simplified to its most essential, albeit, primitive nature.

    Useful references to the simplified approach can be found at the following: http://www.energyscienceforum.com/sh...indemann+Video and at page 30 in http://books.google.com/books?id=Eq8...page&q&f=false

    This should get you started on the right path. So onto the data from the prior post's YZFM configuration. Now we did run the tests again and the following are the simplified/best results for the left, center and right coil positions, noted are the output watts.

    Left edge 8,540 RPM @ 0.84A with 8.34 watts
    Center 8,560 RPM @ 0.84A with 8.36 watts
    Right edge 8,580 RPM @ 0.83A with 8.38 watts

    The load on the shaft was 150 gr in all the above. All this yields a nominal efficiency of about 28%. Not very impressive. However, the purpose of this test was to verify that the magnetic fields are very wide. This result strongly suggests that the Neo length could be extended, at least, to the width of the coil and may improve the performance of this ZFM. James McD. has done this modification and states that it definitely kicks the torque up a notch or two. That will be the next mission - longer rotor and longer/thicker Neo's. Early days yet.

    The Torque testing apparatus (pic below) was built from easily obtainable parts. The vertical support - electrical conduit (0.600"ID) 2 ft. length, (1) Horizontal lever arm - about 3 ft. of 1"x3/4" hardwood or equivalent, (1) 3/8" expandable anchor wedge, 2"Lx3/4" bolt, (1) 4-1/2" steel angle bracket, (2) very small hooks, (2) O'Haus 1000 gram Spring Scales (Davis) and a (1) 1/4-20x 2 1/2"L bolt and nut.One soft leather belt with a rough side. Cut to length desired and punch holes, abrade the area of shaft/pulley contact. Hang weights on lever arm - water bottle works fine.

    Assemble by driving wedge into the conduit flush. Drill a 3/8" hole in the center of the angle bracket. Drill 1/4" hole in conduit about 20'-22" from wedge end. Bolt bracket into wedge and assemble torque apparatus. Clamp to table edge. Go play!

    Happy Thanksgiving,
