4 Wire Dual Output Shaft Motor 20mm Geared DC Motor With Cylinder Gearbox
4 Wire Dual Output Shaft Motor 20mm High Torque Geared DC Motor With 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
