Are graphs available showing motor output torque & power vs speed and the torque limit range for clutches?
I have the info on the motors, I’ll try to get it to you tomorrow (I’m out of town).
Delta
2-wire 393 [high_speed]
(free_speed)=100rpm [160rpm]
(stall_torque)=13.5in-lbs [8.4in-lbs]
(stall_current)=3.6A
(free_current)=0.15A
All motor specifications are at 7.2 volts. Actual motor specifications are within 20% of the values above.

I hope this is helpful.
Here’s GUS’ speedvtourque chart I made a couple months ago, free to download, everything’s safe. If you have any questions feel free to ask.

No, not that I have been able to found. I was just thinking this to myself the other day (about the graphs, that is), and went looking, but unfortunately found nothing.

Check out this thread, specifically this post and this post.
All motors pretty much have the same RPM v. Power parabolic curve, with the mid-range angular velocities and torques being preferred to allow for maximum power.
The slower your motor runs, the more torque you have. The faster your motor runs, the less torque you have. But, to achieve the maximum power, you can gear your motors to run at about half speed. The big point is explained very well, especially in diagrams, on this page (Clicky).
The bottom line:
All good inputs. Thanks everyone!
