Metal DC Geared Motor - 6V 97RPM 1.9Kg.cm

Metal DC Geared Motor (75:1) is a compact brushed drive unit designed for robotics, motion mechanisms, and embedded automation projects. A precision 75:1 metal gearbox converts high‑speed motor rotation into controlled low‑speed output while significantly increasing torque. Rated for 6V operation with a wide 2–7.5V working range, this miniature gearmotor balances power, durability, and efficiency in space‑constrained builds. A robust metal gear train and “D” shape output shaft support stable torque transmission, making this small robotic actuator suitable for wheeled robots, mechanical linkages, and experimental motion systems in prototyping environments.

High Torque from a Precision Metal Gear Train

A 75:1 reduction gearbox multiplies motor output torque while maintaining smooth rotational control. Metal gears provide higher load tolerance and longer operational life compared with plastic alternatives. Locked‑rotor torque reaches 1.9 kg·cm, enabling reliable actuation for lightweight robotic drivetrains, gear assemblies, and motion platforms. Consistent torque delivery allows stable performance in small robots, mechanical arms, and experimental mechanisms requiring controlled low‑speed rotation.

Compact Mechanical Design for Embedded Robotics

A short 23 mm gearbox length keeps overall motor dimensions compact, allowing integration inside small robotic chassis and tight mechanical structures. A 4 mm “D”‑shaped output shaft improves coupling stability with wheels, hubs, and mechanical adapters by preventing slip under torque load. This miniature geared actuator suits mobile robot platforms, gear‑driven mechanisms, and educational robotics builds where space efficiency and reliable mechanical coupling are critical.

Stable Operation Across a Wide Voltage Range

A rated voltage of 6V combined with a 2–7.5V operating range provides flexible compatibility with common battery packs and motor driver circuits. Low no‑load current of about 50 mA supports efficient operation during light duty conditions, while a durable internal structure ensures stable rotation during extended use. This DC gearmotor integrates easily into prototyping systems, small robotic vehicles, and custom electromechanical devices requiring dependable motion output.

Typical implementations include mobile robot drive systems, gear‑driven mechanical prototypes, automatic mechanisms, and STEM learning platforms exploring motion control. The compact gearbox motor provides reliable torque and manageable speed for educational robotics, experimental automation setups, and lightweight mechanical assemblies where durable miniature actuation is required.
