  • Well done Kmarinas!

    Try to use a graphite copper commutator.

    Will give you much more back current spikes

    and keep your batteries charged.

    The electron clustering at the graphite is the real secret of the Newman motors and will give you big back current spikes into the battery, but only, if you use theright dissimular metal commutator parts.

    You direct-convert graphite to free electrons

    which add up in your circuit and recgarge the batteries...

    Regards, Stefan.

  • is there anyway you can find out what is the wind speed?

  • The only way I know of right now is taking a strip of paper and moving with the wind at the speed that it doesn't tilt. This turns out to be 4 ft per second. With a 19" diameter fan, this turns out to be over 470 cfm (cubic feet per minute). Therefore, this machine produces over 200 cfm per watt, which is extremely high efficiency for a non-celing fan.

  • This is a combination of two factors:

    1) The large fan diameter

    2) The low rpm

    2 watts / (4 ft/s) = 1.6 netwons = 0.37 pounds of force

    That is the maximum force we should be able to get from this motor at this power consumption and velocity of output.

  • essentially we can used a fan as the weight for the newman motor, which will endlessly produce power to a wind turbine. this experiment will be part of check list to do, let me know if do anything upon this.

    Good JOB!

  • great!! very high efficiency

  • It would be interesting to see if we can combine a newman machine fan to a wind turbine.
