N20 DC Motor with Magnetic Encoder - 6V with 1:100 Gear Ratio

N20 DC Motor with Magnetic Encoder - 6V with 1:100 Gear Ratio — Adafruit — 4639

N20-format 6V geared DC motor with 1:100 reduction and built-in magnetic quadrature encoder for closed-loop control. Higher reduction than the 1:50 variant gives more torque and lower output speed.
