The VSM20-MG 20mm 12V DC micro geared stepper motor combines a compact 20mm diameter stepper motor with a precision metal gearbox for high-precision motion control applications. Customizable gear ratios allow optimization for specific torque and speed requirements.

Basic stepping angle of 18° (20 steps per revolution). When combined with the gearbox, final rotation angle resolution ranges from 0.05° to 6° depending on selected gear ratio.

1:3, 1:7, 1:10, 1:16, 1:17, 1:20, 1:30, 1:35, 1:50, 1:63, 1:70, 1:86, 1:115, 1:150, 1:210, 1:250, 1:360

Example: At 1:35 gear ratio, torque reaches 800 g·cm at 20 RPM.
