This high-performance DC Gearbox Motor TT 1:120 Single Shaft delivers an excellent balance of speed and mechanical power for demanding educational projects. Operating within a Voltage Range of 3V - 6V DC, it achieves a swift 90 RPM no-load speed (72 RPM at load) and provides a strong Stall Torque of 1.4Kg/cm. Measuring just 64.2 x 22.5 x 18.8mm, it is the ideal choice for agile Arduino smart cars, mobile robotics platforms, and custom STEM builds requiring a compact single-shaft footprint.

 

Stable and Powerful Motion for Your Robotics Projects

Selecting the optimal velocity (RPM) and torque parameters is a foundational requirement for establishing reliable and dynamic robotic locomotion. This DC Gearbox motor features a highly optimized 1:120 gear reduction ratio, resulting in faster rotational wheel speeds compared to deeper gearboxes, while securing ample pushing force to carry microcontrollers, sensors, and structural chassis components seamlessly.

Key Features

  • Locomotion Performance & Torque: Provides a steady output of 90 RPM under no-load conditions and 72 RPM when loaded, yielding a nominal torque of 0.3Kg/cm at 4.5V alongside a powerful Stall Torque of 1.4Kg/cm.
  • Durable Mechanism: Structured with high-grade internal plastic gears designed to suppress mechanical friction and operating noise, providing a light and high-efficiency power transmission layout for DIY makers.
  • Streamlined Mounting: Engineered with a Single Shaft TT mechanical design, ensuring a concentric, secure, and direct slip-free alignment with standard 2mm / D-shaft hobby wheels.
  • Ultra-Compact Dimensions: Built with a slim form factor of 64.2 x 22.5 x 18.8mm, allowing it to easily integrate into tight standard 2WD or 4WD mobile robot enclosures.

Frequently Asked Questions (FAQ)

Q: Can I connect this motor directly to the Arduino pins?
A: No, DC motors demand higher operating current levels than what standard microcontroller logic pins can supply. An external motor driver module (such as the L298N or L293D) must be implemented to manage direction and speed safely.

Q: What is the difference between a 1:120 and a 1:220 gear ratio?
A: The 1:120 gear ratio allows the gearbox to spin faster (higher RPM), giving your mobile robot project more top-end speed, whereas a 1:220 gear ratio rotates slower but delivers greater mechanical torque (pushing force).
