SM15-845G gearbox reducer 15mm PM stepper motor with protective
case
Description:
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.
