Linear / Rotary Motor Tool

Convert a linear-motion spec (screw drive) into rotary motor speed, torque profile and reflected inertia.

Acceleration (m/s2)

Linear speed (m/min)

Platform mass (kg)

Load mass (kg)

Guide friction coefficient

Transmission efficiency

Screw lead (mm)

Screw diameter (mm)

Screw mass (kg)

Motor rotor inertia (kg.m2)

Select a motor whose rated torque ≥ RMS torque and peak torque ≥ peak demand; rotor inertia should match the load inertia ratio.
