Slight adjustments to system yields over 2600 rpm. Still 1.27 volts. Resistance under 0.5 ohms. Duty cycle roughly 50%. Current source is AA battery. Rotating mass still 171 grams.

If I do that, Russ, I have not measured directly, which is my preference. What you propose is an option. However. Since the motor is unconventional I would like to measure several ways if possible. Are you familiar with determining work from wind down data, Russ? I believe my Moment of...

In this motor the current is decoupled from the shaft load. It appears that the energy exchange is different from conventional DC motors. I would like to measure the work done by the rotor. I believe there is a method involving wind downs. You spin up the rotor using an air line and then...

I have a motor I wish to evaluate. I wish to measure the Joules input and output. I believe I am making several errors. Right now I measure the voltage and amperage, calculate watts, and assume that for every second this wattage stays the same. So V*A*seconds = Joules input To...
