Use the Calculate Forces button to silently calculate forces.
These calculations provide the Load Torque that is needed at the outputshaft of a servomotor and gearbox.
A servomotor and gearbox have inertia and they must accelerate with the load. As such, they also need torque. The total torque is calculated with the Kinetostatic TorqueSpeed dialogbox.
See Kinetostatic TorqueSpeed Calculations and Servo motor and Gearbox selection.
