High torque 20BY45-13GR cylinder gearbox D output shaft PM stepper motor
Description:
This is a 20mm PM stepper motor attached with a cylinder gearbox.
We have different gear ratios for choosing, from 10:1 to 350:1
The bigger ratio it has, output shaft rotate slower, and it will have higher torque.
Please make assessment on the torque you require, to determine the gear ratio based on your need.
Output shaft is 3mm diameter D2.5 mm D shaft.
Output shaft’s length is adjustable.
Please feel free to contact us if you are interested in buying few samples to test.

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
Stepper motors are widely used among all industries.
