      I am attempting to obtain a final output speed of 0.01 RPM.

      I have in my possession a BMS60 from aerotech (Servo motor) but I am open to buying a gear motor if it is much cheaper to just gear down a gear motor instead of my current servo motor.

      Here's my problem

      1. Can I use my controller to set the servo speed at sub 10 RPM and then gear it down?
      2. Is it even possible to gear something down to 0.01 RPM (That is to say that 1/100th of a revolution per minute that is to say one revolution every hour and 40 minutes)
      Thanks again for the help!

      If so, can someone send me a link of some of the parts I need, I'm a total noob when it comes to mech eng and just saying : Yeah get a gear motor and a shaft doesn't really help me.

      Thanks again!

      Yes it's possible. Just needs a little thought. What is the torque requirement? What will it have to drive at this speed? How accurate or critical is the actual rpm. How smooth do you need the rotation ( would cogging or stepping be an issue? ).
      A 0.0166rpm motor with very low torque is called a clock......ha ha.
