Micro Worm Gear Motor 050/N30/N20 - 3-12V, 4 to 381 rpm, Metal Gearbox

A compact geared DC motor with a metal worm gearbox, available in eight reduction ratios from 21:1 to 1030:1. Operates on 3–12V and suits models, robotics projects and small mechanisms where controlled speed and torque matter.

Key features

• Eight reduction ratios to choose from: higher ratios give slower speed with more torque, lower ratios give faster speed with less torque
• Two body types (050 and N20): the 050 delivers more torque at the same output speed
• Runs on 3–12V DC; higher voltage increases both speed and torque within that range
• Speed range from 4 rpm (1030:1 ratio) to 381 rpm (21:1 ratio)
• Metal worm gearbox; weighs 24g in the 050 body
• The reduction ratio is fixed once fitted and cannot be changed later

Choose your ratio and body type carefully before ordering—this motor works best in low-load applications where stalling is avoided.
