The datasheet is this one, it doesn't say much besides what I have described before though: https://www.pololu.com/product/1248/specs And I'm not using bearings, just a base that makes barely any contact with the bottom part of the drum and it will be well lubricated.

The weight of the cylinder is about 30 Kg and has a 12 cm radius, I'am also neglecting friction since the drum is over a bushing, maybe that could be interchanged with a safety percentage (I don't know what percentage would be adequate for it), so, if I'm not wrong, and I hope you could redirect...

Exactly, the cylinder is vertical and I want it to rotate about its axis. I am somewhat familiar, I=(m*r^2)/2 for a solid cylinder, but that's where my dilemma comes in, a servomotor has a pre established maximum torque, the one that I'm using is about 5.1 kg-cm, so if I have that maximum...

Hello everyone, I am new to this forum, and here is my first question. I need some help in a particular case regarding torques. Most of the examples given anywhere on the web and books have rotations which are affected directly by gravity like pulleys and such, but, what if I want to calculate...
