TradeSpace — drivetrain studies

Field notes

The workbench accepts vehicle, mission, and drivetrain inputs, then ranks editable motor-and-gearbox assemblies across cost, mass, margin, efficiency, and motor loss. Its starter library contains six rover profiles, including ratios from 25:1 through 100:1 and displayed costs from $182 to $468. The page labels these examples as editable rather than vendor datasheets, and explicitly excludes battery sag, drag, traction, and transient heat from the model.
