Tools to size the right drive.
Free selection tools to help your engineering team choose frames, ratios and torque ratings — built around our standard catalog.
01
Gearbox selection tool
Enter load, speed and ratio to get a shortlist of PG series frames.
02
Torque & ratio calculator
Convert between motor speed, output speed and required torque with safety margin.
03
Load inertia calculator
Check reflected inertia against the motor to avoid oversizing or missed steps.
04
CAD / STEP viewer
Inspect 3D models of every series before downloading the full CAD package.
05
Product configurator
Build a part number by selecting frame, ratio, backlash class and shaft type.
06
Selection guide PDF
A step-by-step sizing reference you can keep offline for your design reviews.
Interactive tools are being finalized. In the meantime, send your load data and an application engineer will run the sizing for you and return a recommendation within one business day.
