Compact 6V DC Gear Motor for Mini Sumo and High-Torque Robot Projects

The Core 6V 400 RPM motor is a compact DC gear motor designed for robot builders who need a strong balance of size, speed, and torque. JSumo positions this motor as suitable for mini sumo robots and other projects that need solid pulling force in a small package.

According to the JSumo datasheet, this motor uses a 48:1 gear ratio, runs at 400 RPM at nominal 6V, and offers 1.2 kg-cm continuous torque with 3.9 kg-cm stall torque. It is also noted as usable at voltages up to 16V.

Why you'll love it

• Robot-ready torque: Suitable for mini sumo and other high-torque robot applications
• Compact body: Easy to fit into tight robot chassis
• Useful speed range: 400 RPM is practical for controlled small robot movement
• D-shaft output: Friendly for common wheel mounting systems
• Good for custom builds: A dependable motor option for many Arduino robot projects

What you can build

This motor is ideal for mini sumo robots, line follower robots, compact drive systems, classroom robot builds, and custom platforms that need a small geared motor with stronger torque than entry-level hobby motors.

Starter bundles

Pair it with a robot wheel pair, motor driver, batteries, and a compact robot controller board for a complete drivetrain.

Recommended add-ons

Add wheel hubs, spare motors, mounting hardware, a robot controller board, and high-traction tires for better robot performance.
