[ATM] Servo Motors: Gear Reduction and Encoder Resolution



Hello,

I want to drive my new alt/az telescope with servo motors.
My motors have 1000 encoder cycles per turn and
a 3.7:1 gear so each turn at the gear output gives
3700 encoder cycles or 14800 signal changes.
This is more resolution than a stepper with 200 steps per
turn and 40 microsteps per fullstep.
But: Is it possible to use a servo instead of a stepper
and control it precisely enough ?
Or should I use more gear reduction ?
The planned gear is 1400:1 so one encoder cycle
is 0.25 arcsec, one signal change is 0.06 arcsec.

Regards,
Martin Cibulski
