ROBOT ARM Torque Calculation
ROBOT ARM Torque Calculation
(OP)
Hello All,
I am designing my first robot.
I have calculated the torque based on this formula T=Fxd +n....., But i have a doubt. can i select the gearbox based on this torque? I think this torque is required torque to rotate the arm from zero rpm. But my robot arm is moving in 15Rpm. How can i calculate the torque needed to stop the arm while moving in 15Rpm?
Many Thanks,
Justin.

RE: ROBOT ARM Torque Calculation
15 RPM is meaningless without knowing how fast you want to ramp to that speed, and how fast you want to ramp back to zero.
RE: ROBOT ARM Torque Calculation
It all starts with Torque = (mass moment of inertia) x (angular acceleration) [T = Jα]
Angular Acceleration = (Change in Angular Velocity) / (Change in Time) [α ≈ ΔV/ΔT]
