    ZFM Advanced Explorations Part II

    Hello to all,

    The summer hiatus from the ZFM Advanced Explorations is now over and the experiments for the next generation of ZFM will begin. Review of the prior ZFM work over the past three years has certainly been exciting, interesting and thought provoking. It did point out one important area of experimentation that had been overlooked and that is the interaction of the rotor Neos with the motor coil poles and the physical location of maximum interaction.

    As a simple first experiment an existing Aluminum 4 pole rotor was modified by removing the existing Neos and placing one large Neo (1.5Lx1.0Wx0.5T) on one pole of the rotor. The rotor and shaft assembly were installed in the original YZFM along with a shaft mounted degree wheel. Both coils were powered up for this first test using a 90 Ah 12volt LAB and the rotor would rotate to the nearest attractive coil pole after being centered in the empty arc between the twin coils. The polarity was then reversed after the degree wheel was zeroed on the attractive pole.

    The original expectation was either the rotor would remain centered or rotate to the attractive pole. The rotor Neo definitely rotated to the attractive pole, however it was the edge of the Neo that positioned itself over one coil end and not the center of the Neo as expected. The polarity was reversed and the rotor positioned itself with the Neo outside edge over the other coil end attractive pole yielding a total of 70-75 degrees of rotation for the empty arc.

    At this point the left hand coil was overheating again, while the right coil remained just warm to the touch. The left coil was subsequently disabled and the experiment completed on the right coil.

    So now the experiment was continued by rotating the Neo position to the center of the coil and applying the power. Again the Neo rotated such that its edge was locked over the coil end and the degree wheel adjusted to zero. The power was then applied at a reverse polarity and the rotor turned to the other pole with the Neo edge again locked onto the magnetic pole yielding a rotation of 105-110 degrees.

    As for the repulsive pole, the Neo was centered manually into the dead zone of the coil end pole where the repelling force is vertical (no rotational force) to the magnets face yielding about 90 degrees (there is a bit of rotational play in this dead zone) for both instances.

    To complete this experiment two other Neo sizes were installed on the rotor and the same experiment completed for each yielding the same general rotational behavior and degree values.

    Next post will expand to two opposing Neos in a N-N configuration. Please hold your comments until the subsequent experiments are completed to flesh out the details.
