This is a 10mm diameter stepper motor attached with a GB12 gearbox(10*12mm).
We have different gear ratio for options, from 2:1 to 1000:1.
With bigger gear ratio, motor’s speed is slower and torque is bigger.
With smaller gear ratio, motor’s speed is faster and torque is smaller.
The gear ratio depends on customer’s requirement.
Before you order samples, please confirm gear ratio.
About motor, we have different coil resistance: 20Ω/40Ω
20Ω is motor suitable for 3.3V DC driving, and 40Ω is more suitable for 5V DC.
The output shaft is 3mm diameter, 2.5mm D-cut shaft.
This is our standard shaft type, we are able to change into lead screw or other shaft type, if D shaft does not fit your need.
