D Output Shaft High Torque 20mm PM Stepper Motor Plus 13GR Cylinder
Gearbox
High torque SM20-13GR cylinder gearbox D output shaft PM stepper
motor
Description:
This 20mm PM stepper motor comes with a cylinder gearbox.
Gearboxes are available in different gear ratios from 10:1 to 350:1
The larger the transmission ratio, the slower the output shaft
speed and the greater the torque.
It can be evaluated according to the torque required by the
customer, and the transmission ratio can be determined according to
the customer's needs.
The output shaft is a 3mm diameter D2.5 mm D shaft.
The length of the output shaft is adjustable.

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
