2 phase NEMA 17 1.8° step angle hybrid stepper motor with planetary reducer
Description:
This is NEMA 17 hybrid stepper motor with a planetary gearbox.
There are different gear ratios available, from 3.71:1 to 719.98
Gearbox’s length 32.2mm~57mm, is related to gear levels.
Shaft type, and shaft length is customizable.
Motor’s torque= original torque*gear ratio* gearbox efficiency
Motor’s speed=original speed/gear ratio

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
