Turbo Metal Gear Worm Motor (12V 160RPM 2.2kg.cm)

Metal Turbo Worm Gear Motor (12V 160RPM 2.2kg.cm) combines a compact DC drive with a durable metal worm gearbox to deliver stable low‑speed rotation and strong torque output. A worm‑drive reduction mechanism provides inherent self‑locking behavior, preventing back‑driving when external force is applied to the shaft. This compact high‑torque gear motor supports bidirectional control through a simple two‑wire connection and allows PWM speed regulation through common motor drivers. Operating from 6–15V with a rated 12V supply, this mechanical power module reaches 160RPM under no‑load conditions while maintaining reliable torque performance for robotics, automation mechanisms, and embedded motion systems.

Self‑Locking Worm Drive Mechanism

A precision worm‑gear transmission prevents reverse rotation of the output shaft when external force is applied. This self‑locking mechanical characteristic enables stable positioning without continuous power, making the geared motor suitable for lifting systems, adjustable platforms, and robotic joints where load holding is required. The worm‑drive architecture also improves motion stability while reducing the risk of uncontrolled back‑driving during power loss or sudden load changes.

Metal Gearbox for High Torque Output

An integrated metal reduction gearbox increases torque capacity while improving long‑term durability under continuous mechanical load. A reduction ratio of 1:37.3 converts the high‑speed rotation of the internal DC motor into controlled low‑speed motion with significant torque amplification. This mechanical drive solution supports applications requiring compact form factors yet dependable force output, such as robotic actuators, automated mechanisms, and small mobile platforms.

Note: Warning: Do not stall motor for extended periods of time to avoid damage to the gearbox.

Common application scenarios include robotics drive systems, automated mechanical assemblies, smart equipment prototypes, and educational engineering projects requiring controlled motion with strong holding capability. This compact worm‑gear motor serves as a reliable actuation component in platforms where stable torque, directional control, and self‑locking mechanical behavior are critical.
