I saw some sort of diagram some place (I think in some sort of Dacta
documentation) stating that you could use a technic motor as a generator.
This makes sense, but I never tried it until today and I am utterly amazed
at how well it works!
I'm using the 2x2 motors that come in the Mindstorms set. I hook two of
these together (without any power source), and hook up a gear to each. Even
if I turn one motor the most minor amount, the other motor turns in
lock-step. When I turn one motor one turn, the other one turns exactly the
same amount!
I've never heard of a generator that was is so efficient!
Will this damage my motor??
I tried the same trick, but hooked up a micro-motor as the secondary. It
turned as well, although at a much slower rate.
I also tried hooking up the "generator" to my aquazone train. I had to
crank it up quite a bit to get the train to move, but I got it going at a
good clip using just my wrist power alone!
The only down side seems to be the limited load that the secondary motor can
handle. If I put even a moderate load on it, then it won't turn unless I
crank the other motor harder (presumably providing more voltage).
