Engineering tools for motion applications — drivetrain design, unit conversion, gear ratios, and motion calculations.
What we do
A focused suite of calculators for the work that sits between motor and load.
Drivetrain Builder
Configure motor, gear stages, and output for a complete drive system, with real-time results.
Unit Converter
Convert between 100+ units across 30+ categories — speed, torque, power, inertia, thermal, fluid, electrical.
Gear Finder
Find optimal gear or pulley combinations to hit a target ratio from your available tooth counts.
Belt Length
Belt-length calculations for three-pulley configurations.
Statusword Decoder
Decode CiA 402 statusword and controlword values used in servo drive communication.
Who it's for
- Engineers designing motion systems, conveyors, positioning tables, and automated machinery.
- Students learning about drive systems, gear ratios, and motion control.
- Motion experts who need quick calculations for sizing motors and gearboxes.
How it's built
Django and Python on the backend, responsive HTML/CSS/JS on the front. All calculations run server-side using Python's Decimal library — one codebase, one source of truth, no rounding drift between browser and API.
