If the rotator doesn't
have a clutch - if you're actually "stalling" the motor when it hits
the end-stop - then you shouldn't keep running it past this point
(might overheat the motor) and should stop rotating when the motor
stalls and the current jumps upwards.



I like that wris****ch concept. But the quoted passage gave me another
idea. If the stalled rotor current is appreciably higher than the
operating current, then that's his end-of-travel indicator, right there. I
can check it myself and the OP will also need to.
