5V 12V DC 12mm N20 Gear Motor with 55mm Threaded Lead Screw Output Shaft KC-GM12-N20
KC-GM12-N20 Micro DC Gear Motor Performance Analysis
The KC-GM12-N20 micro dc gear motor platform integrates a precision brushed n20 motor drive core with a 12 mm metallic spur gearbox housing. Engineered for industrial automation, medical dosage devices, electronic lock mechanisms, and robotic actuators, this n20 gear motor delivers consistent output torque and controlled rotational speed. Available in standard 5.0 V DC and 12.0 V DC voltage configurations, the system supports nine distinct gear reduction ratios ranging from 30:1 to 380:1 to accommodate specific engineering load requirements.
