        This new link you kindly included does not work either. I get the same error message Davy quoted above, cannot see Davy's posts in question.

        thanks for trying to help.

          I simply gave you my opinion on the notes as a reply to your post."

          That has been my experience in the past, but yesterday it flashed on screen "waiting to be approved by moderator" and I still don't see it listed anywhere on the main bedini forum thread list, so if you have replied, can you please share a link for me here so I can find it?

          When I replied, it looked like a regular post that everyone could see. That was the whole reason I replied to it.

          I found that in front, it did say moderated, so I approved it.

          I have no idea why once in a blue moon a post will require moderation - might be the quantity of images or something.

            I think because you have moderator status. That is how it came up for me and did not notice that it was flagged for moderation somehow.

            • I went in and approved Aaron's post as well. Not sure why it was moderated either but hopefully everyone can see the thread/posts now.

                Thanks for straightening it out. I bet the system flagged it because I posted pictures from a link instead of uploading to this system. Probably part of a porn spam filter on this site, I'm guessing...

                  Hi James. My mistake, I only found one video of a brake test on a ZFM by DadHav on youtube.
                  DIY Dynamometer (Prony Brake)
                  This test indicated 56% efficiency on his ZFM.
                  The other brake test I found by Peter Lindemann was on a conventional electric motor, not a ZFM.
                  And although 56% is a poor showing, I am well aware that every motor has a sweet spot for efficiency depending on load, rpm and other factors so 56% under one set of conditions does not mean it can't go overunity under different conditions. At these power levels I believe the hydraulic bicycle disk brake would allow good testing duration (water spray or tray on disk may be required), controllability and readability (a single gage to read with no calculations for torque results by using a fish scale or a table scale). Putting a test run on video would eliminate the need to keep your eyes jumping back and forth and frantically writing notes as you change loading, you just freeze the video later as you note all readings (amps, volts, pounds, rpm) at each step when you change loading. I would mount the brake caliper on a lever arm with one end connected to the motor shaft with a bearing and the other end preferably one foot long with a contact point resting on the table scale. I have a Polder scale (I may have bought at Costco) 3/4" x 8" x 8" with a limit of 5kg/11pound and 1g/0.1 ounce resolution.
                  Hi Richard --

                  I just finished doing the new magnet test today. The results were positive. My torque was tripled from the original magnets I had on my ZFM and my ZFM speed increased by 1/3. The torque now is equal to or a little bit stronger then the Peter L. build. The original magnet size was N52 3/4 inch round by 1/2 inch tall. These were changed to N52 2 inch by 1 inch by 1/2 inch. The magnets were not glued at the time and they came off once the ZFM reached 9500 RPM running on +24 volts. Two magnets were destroyed in this test. The next test they will be glued. I expect to see higher RPM's with the next test. Good thing I bought two extra magnets. Another positive result from this test is my build stopped vibrating and now runs smooth. The biggest thing learned from this test is don't buy your magnets till you finish winding your coil. The magnet has to be at least the width of your finished coil so that the magnets's magnetic field cuts through all the magnet wire on your coil. My coil was very different from the original Peter L. build in that it has only one wire on each side but it's 18 gauge magnet wire which makes my coil bigger and wider to get the 3 ohm resistance I have on each side.

                  I feel a need for speed!!!

                  • Great results there James! Looking forward to a video of the improved setup, if you have time.

                    Just a word of warning when working with neo magnets. If they break, be very careful not to cut yourself with the shards or broken bits. I did this once and felt sick for a week, some sort of poisoning.

                      Hi John --

                      Thanks for the warning but I wear thick gloves when handling these magnets. I am well aware of the fingers getting pinched or cut.
                      Been there Done That. The test was suppose to be a short test to see if the torque increased. I got carried away and kept on testing. I
                      will epoxy the magnets before the next test.

                        I can't wait to see a brake test.
                        Did you have a chance to see if the current draw went up?

                        Hi Richard --

                        I was not monitoring the current at this point in time due to this was only a test to see if the bigger
                        magnets produce more torque. I will be gluing magnets on my rotor for the rest of the week to try and
                        get ready for next weekend's testing. Can only handle one of these magnets at a time and will glue them
                        on one at a time with a 24 hour cure time of the Epoxy.

                          The attached picture is the damage caused when one magnet flip up off the rotor and crashed into two other magnets before
                          the rotor abruptly stopped with the magnets all mashed between the rotor and the coil.

                              "So yes use big honking mags and distribute the flux ... that's my guess." Post on this thread from 11/15/16. Earlier in the thread I said "Has anyone else been working on this recently? I have, I understand now why it is called a zero force motor and it is blowing my mind." I saw with really simple experiments there was no increasing Lenz with increasing permanent magnet strength or increasing electromagnet strength. From glancing at the conference notes there is some Lenz associated with the machine, however I think James makes the point well. Two points earlier in the thread from JB 1) "This machine is running in an A field where no magnetism should escape or effect anything on the outside of the machine." 2) " if the group can build and understand the way it operates in a simple form before you move on to a much bigger unit." JB said something else on this thread, " I want you to look up something that had to do with Joe Newman." I thought that was a pretty odd thing to say regarding the ZFM so I read Joe Newman's book and am real glad I did. Course he also said something about he came upon this while working on a magnetic motor, which is lost to us like the Giza pyramid right now.

                                He shows HP as 0.05866 and the elec. HP as 0.0495979. That's more mechanical horsepower out than electrical horsepower in for an overunity efficiency of 118% if I am understanding his labeling correctly. I do not see any description of his measuring methods for the mechanical horsepower.
                                It was my understanding those are Bedini-Cole notes that came way after the ZFM and are different. Some similarities, but different.
