Metal DC Geared Motor - 6V 357RPM 0.7Kg.cm

Metal DC Geared Motor - 6V 357RPM 0.7Kg.cm delivers compact mechanical power for robotics mechanisms, motion prototypes, and small automation systems. A 20:1 metal reduction gearbox combines stable rotational output with strong torque in a space‑efficient form factor. The 6V brushed DC motor platform provides reliable speed control using common motor drivers and controller boards used in maker and engineering environments. With a durable metal gear train and a D‑shaped output shaft designed for secure coupling, this compact geared actuator supports wheeled robots, mechanical linkages, and educational mechatronics projects that require dependable low‑voltage motion control.

High Torque in a Compact Drive Unit

A precision 20:1 metal gearbox converts motor speed into usable mechanical torque, delivering up to 0.7 Kg.cm locked‑rotor torque while maintaining a compact footprint. The geared drive provides stable output rotation suitable for small robotic drive systems, actuators, and mechanical transmission assemblies. A no‑load speed of approximately 357 RPM at 6V balances responsiveness and controllability, allowing smooth integration with common PWM motor controllers for precise speed regulation in mobile robots and mechanical prototypes.

Durable Metal Gear Reduction Mechanism

An all‑metal gear train improves wear resistance and operational stability compared with plastic gearbox alternatives. The reinforced reduction assembly maintains consistent torque transfer under repeated load cycles, supporting robotics experiments, classroom engineering builds, and long‑running automation demonstrations. A 19 mm gearbox length keeps the drive module compact while preserving structural durability, making the geared motor suitable for chassis assemblies, mechanical arms, and other moving structures that demand reliable gear transmission.

Robotics‑Ready Shaft and Electrical Compatibility

A 4 mm D‑shaped output shaft simplifies coupling with wheels, hubs, and mechanical linkages while preventing slipping during torque transmission. The 2–7.5V operating voltage range allows compatibility with typical battery packs used in educational robots and mobile prototypes. Stable current characteristics and straightforward two‑wire DC control allow easy integration with motor driver boards, microcontroller projects, and classroom robotics platforms.
