Metal DC Geared Motor - 6V 191RPM 1Kg.cm

Metal DC Geared Motor - 6V 191RPM 1Kg.cm is a compact brushed gearmotor designed for robotics, smart mechanisms, and motion-driven maker projects. A 34:1 precision metal gearbox delivers reliable torque amplification while maintaining a small mechanical footprint, making the motor suitable for space‑constrained mobile robots and mechanical assemblies. Stable electrical characteristics within a 2–7.5V operating range allow easy integration with common development platforms such as Arduino controllers and motor driver boards. Durable metal gears, a D‑shaped output shaft, and consistent rotational performance support long‑term use in experimental prototypes, educational builds, and compact automation systems.

34:1 Metal Gear Reduction for High Torque Output

A precision 34:1 metal gearbox converts high‑speed motor rotation into increased torque, enabling the compact drive unit to reach a locked‑rotor torque of 1 Kg.cm. Such mechanical advantage benefits small robotic vehicles, drive wheels, and mechanical linkages requiring controlled force rather than high speed. Metal gear construction also improves wear resistance compared with plastic gear trains, supporting stable operation during extended robotics experiments or mechanical prototyping tasks.

Compact Mechanical Design for Embedded Robotics

A gearbox length of only 21 mm combined with a 4 mm D‑shaped output shaft allows easy installation in miniature robot chassis, gear assemblies, and small automated mechanisms. The D‑profile shaft improves coupling stability with wheels or hubs while preventing slippage under load. Compact geometry makes the motor particularly suitable for lightweight robotics platforms, smart vehicle prototypes, and educational engineering kits where internal space remains limited.

Wide Operating Voltage and Stable Performance

An operating voltage range from 2V to 7.5V supports flexible power supply choices across battery‑powered robots and microcontroller‑driven motion systems. At 6V, the geared motor delivers a no‑load speed of approximately 191 RPM with low no‑load current consumption of about 60 mA. Consistent electrical behavior simplifies integration with common H‑bridge motor drivers and controller boards used in embedded robotics development.
