100% brand new from STEPPERONLINE (The No 1 distributor in the world for stepper motors and drivers).

This NEMA 11 motor has an integrated Economy Planetary gearbox with a 26.85:1 ratio. From the output shaft of the gearbox, the step angle approximately 0.067 deg. The motor part is standard hybrid stepper motor with size 30 x 30 x 50.5mm, and 0.67A rated current.
This Economy Planetary gearbox can only promise Backlash at No-load <=1 deg., so if you need higher precison, please choose Precision Planetary Gearbox.


This motor must be controlled by a constant current or chopper drive controller. Connecting the motor directly to a power supply will destroy the motor and void the warranty.
