0.9 degree 1.8 degree step angle 42 mm Name 17 Hybrid Stepper Motor w/ Planetary Gearbox
Description:
This 42mm square hybrid stepper motor has a planetary gearbox.
We have different combinations of gearbox gear ratios for you to choose from.
The output shaft is a slotted round shaft.
The output torque of the motor is related to the length and transmission ratio of the motor.
In addition, we have different gearbox ratios and motor lengths to choose from.

Application of stepper motor:
Stepper motors are used for precision control, 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 rotation/linear motion.
Advantages of stepper motor:
Stepper motors can achieve precise control even without closed loop encoder/feedback system and without brushes. Therefore, there is no electromagnetic interference and spark problems. In some cases, they can replace dc brushless/brushless motors.
The stepper motor is easy to control through the driver, which establishes its important position in the field of precision control.
1. Can realize accurate control, programmable
2. No electromagnetic interference and electric spark
3. Small volume
4. Reasonable prices
5. Low noise
6 long service life
