This NEMA 23 stepper motor has 76mm body and 4.2A rated current, integrated with a PLF series precision planetary gearbox of gear ratio 5:1. It's an ideal solution to the applications that required limited space but low speed or high torque. Thanks to the PLF series gearbox's built-in shaft coupling, the motor or gearbox can be replaced easily.
