Ok, from the rs link that you posted, it written 10.5mNm. Means it has this amount of torque right. Then, the gearbox that i have now is 190:1. So, means i only have total torque of 1.9 Nm?
Btw, is there any nice tutorial for DC servo? Cause I am still don't know much about this motor and how to control it. Is DC motor same with DC servo? Can I control it with PIC if i have DC servo motor controller since it has H bridge in there?
