5V DC 8mm length output shaft worm gearbox with 15mm diameter PM stepper motor
Description:
This is a 15mm motor attached with a worm gearbox.
We have different gear ratios on gearbox.
Also motor’s coil resistance/cable length/cable color is customizable.
About worm gear, it has low efficiency and self lock function.
Low efficiency: Efficiency of a worm shaft is only about 34%
Self lock function: motor’s shaft is completely lock when power is off. This function is very useful in some case.

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
