Calculate Forces

Use the Calculate Forces button to silently calculate forces.

These calculations provide the Load Torque that is needed at the output-shaft 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 Torque-Speed dialog-box.

See Kinetostatic Torque-Speed Calculations and Servo motor and Gearbox selection.

To calculate Kinetostatic Forces:

The kinematic-chain must be kinematically-defined.
There is a minimum of one Part in the kinematic-chain that has mass.
The Power Source should be configured to act at the correct Joint, Cam, Gear-Pair or Spring with the Configure Power Source dialog-box.
