This is our 15mm motor attached with a gearbox.
This gearbox size is 12mm*10mm. (Length*Width)
We have different gear ratios for choosing, from 2:1 to 1000:1.
Customers can choose gear ratio base on their speed and torque requirement.
The bigger gear ratio it has, motors will have slower output speed and higher torque.
Also, there is a plastic case to protect gearbox, provide dust-proof protection.
If customer’s do not want the plastic case, we can get rid of it.

Application of stepper motors:
Stepper motors are used for precise control, widely used on medical equipment, 3D printer, industrial precise control, automation equipment, etc.
Stepper motors can be used in any mechanisms requirement precise conrtol and rotational/linear movement.
Advantage of stepper motors:
Stepper motor can reach precise control even without close-loop encoders / without feed back system, also they do not have electrical brushed. Thus there is no electromagnetic interference and electrical sparks issues. In some cases, they can replace DC brushed motors/ brushless motors.
Stepper motors are easy to control with drivers, and this feature establish its important position in the field of precise control.
1. Precise control achievable, programmable
2. Without electromagnetic interference & electrical sparks
3. Small size
4. Reasonable price
5. Low noise
6. Long service life
Stepper motors are widely used among all industries.
Samples are packed with foam sponge inside paper box.
