(: 00163 = days since my first newman motor :)
This motor has a very high torque constant - about 1.6 Newton-meters per amp or 1.2 lb-ft per amp. I took three independent measurements by hand (: ***see bottom for details*** This is the result of sending the same amps through a higher number of larger turns than in conventional motors. Torque is angular momentum per unit time, so this motor produces great amount of turning ability. Because of that, fan works best at high blade pitch. In this case it works very well at a 45 degree pitch whereas fan blades designed for today's top quality fans have around 25 degrees of pitch.
Power is energy per unit time. THIS IS OUR INPUT.
Voltage is magnetic flux per unit time. THIS IS WHAT DRIVES THE COIL AND THE MAGNET.
Torque is energy per unit angle. THIS IS WHAT DRIVES THE SHAFT, THE FAN, AND THE WIND.
Fan blade RPM owes it's existence to fan torque.
Fan torque owes its existence the force on the magnets through a distance per revolution.
The force on the magnets through a distance per revolution owes its existence to the applied magnetic field of the coil.
The magnetic field of the coil owes its existence to???? [Look at the current in the video]

"The energy machine is proof that the strength of the motor's magnetic field is dependent upon the VOLTAGE --- NOT the CURRENT!" - JosephNewman.com
"Voltage leads current in an inductor." - Basic Electrical Engineering
"There are no real size constraints with respect to his technology and there are two methods of increasing the energy output: increase the amount of copper utilized in the conductor coil and/or increase the rpms of the commutator. The latter can be done by increasing the applied voltage (not the current which is what costs money) up to the maximum atomic alignment of the atomic domains in the copper conductor. And, if you seek to align more atomic domains, then use more copper. Once the atomic domains of the copper conductor are aligned, the copper becomes magnetic and thereby releases energy electromagnetically in accordance with E = mc²." - Joseph Newman Publishing Company

Since incremental resistance equals change in voltage per change in current, the time constant of an inductor segment (inductance divided by incremental resistance), is actually the ratio of change in magnetic flux produced per change in voltage. Obviously if the circuit has no inductance, no magnetic flux will be produced regardless of the currents or voltage. In short, a ***thicker*** coil (as required to achieve a higher planned time constant) will give more magnetic "bang" for your "volt".

Crude measurements I took of this fan motor are as follows:
When moving:
1) 1/7 pound force; 2 inches from shaft; 1/42 pound feet; 0.02 amps avg
2) 5 pound force; 1.5 mm from shaft; 1/40 pound feet; 0.02 amps avg
When stalled at ON position:
1) 1 pound force; 2 inches from shaft; 1/6 pound feet; 0.14 amps avg (7x current); (1/6 pound feet) / 7 = 1/42 pound feet
What's its RPM?

By eye, I can tell it is 22 rotations per 5 seconds, so its 264 rpm.
If you looked at the text in the description, you might have wonder then what is the power output.
*If* there 1/42 pound feet of torque like my description claims all one has to do is convert that into newton-meters then multiply by two pi and the rpm/60... 0.89 watts. Therefore this may be really high efficiency. Let's me just say for the sake of argument that it's NOT overunity. :)

And I am probably wrong. Soon I am going to increase the wind output of the fan by 20x of the one in this video and only between 2x and 3x more power using 60 something volts, twice the coils, and 19" instead of 12". So the real efficiency of the motor above should be something like less than 15% efficient if my next demonstration under-unity still. :)
