DadHav,
I saw that video before, but thanks for posting it again. The most SIGNIFICANT thing for me was that the two radio shack motors hooked together ran on .84 amps at 6.8 volts. When I did this exact same test my motor ran at .82 amps, but 12.3 volts. This is a major issue that we need to address. It cost you 5.6 watts of power for one motor to run the other, while my test showed 10.08 watts to do the EXACT SAME thing. (provided of course that they ran at exactly the same rpm, which I strongly doubt) That is TOO much variation of the baseline data to give us results that are worth ANYTHING. (without that third piece of info, which is rpm of the motor, not to mention the inductance of the two motors) If my modified motor cut my watt usage in HALF which would be dang exciting for ME (if I didn't know better) I would be at the SAME watt usage you are at NOW with NO modification to the motor. This is why data, and ALL the data is critical. Not just bits and pieces of it.
I think we are on the same page bout THAT!
WE need to run these motors on a set voltage powering a set load and until we get some data from a lot of folks, we don't even have a strong baseline on which to base ANY conclusions about what modifications are doing. How many of you have a variable power supply so we can at LEAST get some baseline data of one standard motor running another one on a SET voltage if we come up with a standard bulb we can use as a load???? If we are not going to be scientific about this, lets just get out our book of spells and our magic wands.
