    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.

    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.

    Hi John --

    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.

    I feel a need for speed!!!

    "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.

    On 7-21-17, Davy Oneness gave 5 links in his post. The second link shows JB's calculations on the ZFM.
    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.

    Thanks for pointing that out, Aaron.
    In those notes dated 6-17-89 he refers to it as the LCF motor. It looks a lot like the window motor to me but I am not familiar enough with the ZFM or the other two to know the differences between the three of them.
    I built the MEG a long time ago (no moving parts) and the SSG more recently.
    I would like my next project to be a motor that has the potential to lead to a design that will run my car and eventually an airplane (180HP) and will order your book on the ZFM next week.

    I have a folder I downloaded called "Bedini -Cole Window Motor Lab Notes" that I think Dave Wing posted a couple of years ago. One file shows a "multi pole inside out Faraday motor" dated 8-1988 (Cole - Bedini). In another file (by Cole) dated 9-1989 it's called a "6x6 LCF motor" and looks to be the same as a 6 pole window motor. And in a file dated 8-1988 (Brown, Cole, Bedini) showing the details of the rotor, it's called an LCF DC motor (Linear Counter Field). I think these are all early terms to describe what we now call a "window motor".

    And there is yet another file showing a "Faraday type Ironless Motor" which looks to be what we now call the "Zero Force Motor" (ZFM).

    My take away is that the window motor and the ZFM are two different versions of an ironless Faraday motor and exhibit very similar operating characteristics.
