All categories at a glance: each one bundles related calculators - from preliminary sizing to verification. One click on a tool starts the calculation right in your browser.

Drive sizing

7 tools

From motion profile to motor: torque, speed, power and reflected inertia for linear and rotary axes. With the drive sizing calculator, motion profile, mass moment of inertia, slider-crank and brake sizing, this category covers the complete preliminary design of a drivetrain.

Automation & handling

9 tools

Sizing calculators for handling technology and special machinery: cycle times of positioning axes, ball screws, indexing tables, gripper and vacuum technology, shock absorbers and toggle clamps. Ideal for the fast concept phase of automation solutions.

Drive technology

7 tools

Classic drive elements: cam design per VDI 2143, spur gears per ISO 6336, bevel and worm gears, chain drives, cylinder forces and the critical bending speed of shafts.

Strength

9 tools

Strength verification for components: beam bending with many load cases, buckling, torsion, tension/compression, equivalent stress, Hertzian contact, fatigue, area moments of inertia, pressure vessels and shaft calculation per DIN 743.

Steel construction (EC3)

2 tools
