♦ Overview:
This closed spur gearhead N20 DC Gear Motor (IND‑14GMN20) is a compact Ø14mm closed spur gearhead micro DC gear motor designed for environments where open gear trains may be affected by dust, fibers, or frequent handling. The enclosed gearbox helps protect the gear train and keep output more stable over time. Whether you are building a low‑speed high‑torque drive or a faster micro gearbox solution, this closed spur gearmotor offers a practical balance of size, durability, and flexible configuration for OEM and prototyping needs.

A closed gearhead provides better protection against dust and handling damage, reducing contamination‑related wear and improving stability in practical assemblies.
Higher ratios reduce output RPM and increase output torque/holding margin. Choose ratio based on the required loaded RPM and the torque margin you need to avoid frequent near‑stall conditions.
