Thanks Eric,
Interesting. Possibly too complicated for my own particular intentions
regarding cost and minimal requirements/underbuilding but certainly
something for later, after I have learned to walk.
What might be interesting is to see if the amps to power ratio can be
changed this way, I suspect it would, probably not enough to matter, but
if so it would represent an efficiency gain, thus a range increase. I
was thinking more of an adjustable setup. Might be easy to do on some
motors, just by slotting out holes. I will look it up on EV sites,
thanks.

Hi John
Yep, you can do that. Any gains in one direction are offset by losses in
the other direction, i.e. reverse or regen. But some may feel that the
tradeoff would be worth it. The EV guys, who have much higher torque
and power requirements than we do, do this quite often.
Eric
