Metal DC Geared Motor - 6V 20RPM 7.5Kg.cm
Introduction
Metal DC Geared Motor – 6V 20RPM 7.5Kg.cm features a compact brushed DC drive paired with a high‑ratio 362:1 metal gearbox, delivering strong torque in a small mechanical footprint. This compact gear reduction motor is designed for robotics motion systems, smart mechanisms, and compact automation projects where reliable low‑speed rotation is required. A durable all‑metal gearbox improves wear resistance and transmission stability while maintaining efficient torque output. The 6V geared actuator provides controlled rotational speed with high load capability, making the motor suitable for mobile robots, mechanical arms, small conveyor mechanisms, and various embedded engineering builds.
High Torque from 362:1 Metal Gear Reduction
A precision 362:1 metal gear train dramatically increases torque output while reducing rotational speed to a controlled 20RPM at 6V. This high reduction ratio enables the compact actuator to deliver up to 7.5Kg.cm locked‑rotor torque, allowing reliable motion in load‑bearing robotic mechanisms. The metal gearbox structure enhances durability and minimizes wear during continuous operation, making the gearmotor appropriate for mechanical assemblies that require sustained torque and long service life.
Compact Size with Stable Mechanical Performance
A small 27mm gearbox length combined with a 4mm D‑shaped shaft enables secure coupling with wheels, gears, and mechanical linkages. The compact DC reduction motor integrates easily into mobile robots, educational engineering kits, and embedded mechanical systems where installation space is limited. Stable current characteristics and moderate no‑load current contribute to predictable electrical behavior when integrated into motor driver circuits and robotic control systems.
