1.8 Degree 0.9 Stepper Motor 42mm (NEMA17) With Planetary Gearbox Multiple From 3:1 To 200:1 Of Gear Ratio
Planetary gearbox with 0.9 degrees 1.8 degree step angle 42 mm hybrid stepper motor
Description:
This 42mm square shape hybrid stepper motor with planetary gearbox.
We have different gear ratio combinations for you to choose.
The output shaft is a round shaft with a slot.
Motor’s output torque is related to motor’s length and gear box ratio.
We have different gearbox ratios and motor length for choose.

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
