Thanks a lot again.
So the resolution increases a lot, but what I need is an accuracy of 0.3 degrees.
I found one very cheap servo with integrated gearbox here (I also found two geared steppers on robot market place, thanks itsmoked, but unfortunately they were out of stock). However, the...
Okay, thanks a lot to all!
Two more questions;
1. Is the accuracy related linear to the gear ratio? (I do think so, but just as a check)
2. Would I need metal or titanium gears? As I think plastic gears will break under these forces.

@Skogsgurra; thanks for your reply.
The most common stepper motors have an accuracy of .9 or 1.8 degrees. The more precise but powerfull steppers are actually equivalent to servos right?
And is there any website where you can find a motor on base of specs? Like min. torque, max. price, min...
Hi everyone,
For a project in Linear Fresnal Mirrors - Solar power at the universiry UFSC (Brazil) I need a motor to position the mirrors. I have estimated the desired torque, which is about 30 Nm. The desired rpm is very low. An rpm of order 10^-1 would satisfy. The desired accuracy is about...
