Have a Compact Transmission Problem?¶
SigGear works with engineers on custom micro planetary, planetary, cycloidal and motor + gearbox transmission solutions. You do not need to have every parameter defined before the first discussion.
Start with the application, motor, drawing, available space or motion target you already have. SigGear can review the transmission approach, identify missing inputs and evaluate a path toward prototype and production.
