This is a NEMA 17 hybrid stepper motor with planetary gearbox.
It is available in different gear ratios from 3.71:1 to 719.98
The length of the gearbox is 32.2mm~57mm, which is related to the gear position.
Regarding shaft type and shaft length can be customized.
Motor torque = raw torque * gear ratio * gearbox efficiency
Motor speed = original speed / gear ratio

Stepper motors are used for precision control and are widely used in medical equipment, 3D printers, industrial precision control, automation equipment, etc.
Stepper motors can be used in any mechanism that requires precise control and rotational/linear motion.
If there is no closed loop encoder / no feedback system, stepper motors can also achieve precise control, no brushes. So there is no electromagnetic interference and spark problems. In some cases, they can also replace DC brushed/brushless motors.
The stepper motor is easy to control by the driver, which has established its important position in the field of precision control.
1. Precise control and programmable
2. No electromagnetic interference and sparks
3. Small size
4. Reasonable price
5. Low noise
6. Long service life
Stepper motors are widely used among all industries.
Samples are packaged with foam sponges in carton boxes.
For mass production, products are packaged in cartons.
For sea shipping (mass production), cartons are packed on pallets.
