Product Overview
The NEMA-17 Bipolar Stepper Motor with 100:1 Planetary Gearbox offers substantial torque multiplication and precision step control in a compact form factor. With a 100:1 gear ratio delivering approximately 566 oz·in of holding torque, this motor is well suited for robotics, automation systems, CNC indexing, and other motion control applications that require high torque at controlled speeds.
The planetary gearbox provides efficient torque translation and reduced backlash, while the bipolar stepper driver compatibility allows precise open-loop control using common drivers like A4988 and DRV8825.
