In ref to "using motor as generator..." Jan 5th:
We had placed a small 15V .5A incandescent bulb in front of the main resistive load, just for a kind of visual cue.
Noticed when testing circuit with a stable 15V DC power source there was a differnence in bulb luminosity. Took almost 24V to acheive the same luminosity with circuit connect to the wind rig both with a flow in the wind tunnel and hooked as bootleg genset.
Does this have something to do with amplitude or frequency of the output from the motor, and, if so, does that need to be figured into calculations of power output.
Just as a note, we are mainly looking for relative power output of different rotor configurations and profiles on the same motor, but it would be nice to compare results generally.
