The Electroboat 6mm Shaft Dummy Motor Axle Hub is an essential mechanical component for mobile robotics, specifically built to serve as a passive, non-driven wheel mount. In many 4-wheel drive (4WD) or differential drive robot designs, using motors on all four wheels increases weight, battery consumption, and motor driver complexity.

This dummy axle unit mimics the standard mounting dimensions and 6mm shaft profile of a conventional center-shaft DC geared motor. It mounts directly to your robot chassis using standard motor brackets and lets your robot's front or rear wheels rotate freely with minimal friction. Made from high-strength engineering polymer with an integrated smooth axle, it ensures balanced weight distribution and stability across all four contact points.

Key Features and Benefits

• Free-Rotating Dead Axle: Allows wheels to turn smoothly without resistance, eliminating battery drag on passive wheels.

• Standard 6mm Shaft Diameter: Fits all standard 6mm center-hole robot wheels (7x2cm, 7x4cm, 85mm Pro, etc.).

• Identical Motor Mount Form Factor: Matches standard DC geared motor body profiles for easy installation using standard L-clamps or brackets.

• High Load-Bearing Capacity: Supports chassis weight evenly to prevent sagging, wobbling, or structural stress.

• Cost & Power Efficient: Reduces overall project cost and extends battery run-time by replacing extra unneeded motors.

Technical Specifications

How to Use

1. Secure the dummy motor body to your robot chassis using a standard 6mm DC motor L-clamp bracket.

2. Slide any 6mm bore robot wheel onto the 6mm exposed output shaft.

3. Tighten the set screw on the wheel hub against the dummy shaft to secure the wheel in place.

4. Test the wheel manually to confirm smooth, unhindered rotation.
