      Hi all
      I am using spur pinion and driven gear mechanism to rotate a cylinder. Outer diameter of pinion is 30mm and that of driven gear is 60mm. Mass of cylinder is 500 grams. I have to select a motor of suitable torque for this purpose. Will anybody help me how to calculate torque???

      For starters, I think you need the P.D. of both gears, not the O.D.

      You also need the radius of gyration for the cylinder and a definition of what the load is and the friction it is resisting.

      Finally, you need a better definition of the problem. For instance, a long small diameter 500g cylinder spinning at constant speed with ball bearings is going to require a lot less torque than a 500g cylinder with no bearings and a large O.D. starting at rest and needing to come up to speed in 0.1 second.

      Hi twebb, In the software there is a tab "Sprache" (if it is in german), where you can select to english (or another language).
