Re: (ET) Lift motor control

["steves" <ssawtelle fcc net>]

We just had some discussion on this recently (November, I think).

As I recall, running at higher voltage can work, but with adequate cool 
down
time - for example, the tiller load and duty cycle may be too great. 
Several
listers run at 24V successfully. Hmmm - Perhaps you could run fast when
taking up slack then throttle down when lifting a load. That would be nice,
esp when running a double pulley for increased lift capacity.
