Round geared stepper motor 20mm micro Geared Stepping Motor 2 phase
4 wire mini gear stepper motor with Gearbox
Description:
SM20-020L-GEAR MOTOR 20mm stepper motor is composed of a miniature
stepper motor with an outer diameter of 20mm and a precision metal
gearbox. The deceleration ratio can be customized according to the
customer's needs.
The deceleration ratio of this image is 1:195.3, This series of stepper motor deceleration ratio has:1:10 1:12.5 1:25 1:31.25 1:50 1:62.5 1:78.1 1:100 1:125 1:156.25
1:195.3 1:250 1:312.5 1:390.6 1:488.3
The basic stepping Angle of the motor is 18 degrees, which is 20
steps per lap. Combined with the deceleration effect of the
reduction gearbox, the rotation Angle resolution of the final motor
can reach 0.05~6 degrees.
The customer can select the speed reduction ratio according to
different torque speed requirements, and at the same time, the
appropriate driving frequency of the stepper motor can achieve the
determined speed and torque.

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.
